    Molten carbonate fuel cells (MCFC) are being developed for large- scale power generation. One source of fuel is coal gasifiers, which presents the problem of coal gas contaminants and their effect on MCFC; HCl is the most serious and hence needs to be monitored. Different methods of detecting HCl in the gas phase were evaluated, and laser diode absorption is the most suitable. Temperature sensitivity and spectral interferences are discussed; it is shown that the P10 spectral line is the best. A diode for the P10 line is on order; experiments using the P5 line show the line to be unacceptable (overlap with CH{sub 4} line). Future planned work is outlined briefly. (DLC)

    This paper outlines a project, funded under a DOE SBIR grant, which tested a potentially lower cost method of manufacturing MCFC stack anodes and evaluated the feasibility of using the technology in the existing M-C Power Corp. manufacturing facility. The procedure involves adding activator salts to the anode tape casting slurry with the Ni and Cr or Al powders. Two different processes occur during heat treatment in a reducing environment: sintering of the base Ni structure, and alloying or cementation of the Cr or Al powders. To determine whether it was cost-effective to implement the cementation alloying manufacturing process, the M-C Power manufacturing cost model was used to determine the impact of different material costs and processing parameters on total anode cost. Cost analysis included equipment expenditures and facility modifications required by the cementation alloying process.

    In this paper, various (molten carbonate fuel cell) MCFC cell/stack and network arid system models available in the public domain are discussed. Parametric and phenomenological fuel cell mathematical models are being used to simulate individual MCFC cell/stack performance. With initial demonstration of full-area, full-height 250-kW to 2-MW MCFC power plants, the spatial configuration of the MCFC stacks into networks in the fuel cell power plant takes on new importance. MCFC network and power plant system flowsheet performance is being modeled using-the ASPEN system model. ASPEN is a tear and iterate flowsheet simulator in the public domain. ASPEN is suitable for MCFC network simulation since it has strong systems and property database capabilities. With emergence of larger MCFC power plant system demonstrations, system modeling of MCFC power plants is now essential. DOE routinely uses MCFC models in making performance comparisons and in decision-making.

    Toshiba is working on the development of MCFC stack technology; improvement of cell characteristics, and establishment of separator technology. For the cell technology, Toshiba has concentrated on both the restraints of NiO cathode dissolution and electrolyte loss from cells, which are the critical issues to extend cell life in MCFC, and great progress has been made. On the other hand, recognizing that the separator is one of key elements in accomplishing reliable and cost-competitive MCFC stacks, Toshiba has been accelerating the technology establishment and verification of an advanced type separator. A sub-scale stack with such a separator was provided for an electric generating test, and has been operated for more than 10,000 hours. This paper presents several topics obtained through the technical activities in the MCFC field at Toshiba.

    A simple three dimensional model was developed to simulate the temperature distribution and the performance of various flow types of the MCFC stack. The objective of this study was to understand the complicated phenomena occurring in the MCFC stack and to supply the basic data for optimizing the operating condition of the MCFC stack. Assuming that the stack consists of a number of differential elements which have uniform temperature and gas composition, the model was solved by finite difference method. The performance of this model was demonstrated by comparing the calculated value with experimental data of the 1.5kW class co-flow type MCFC stack operated in KIST. This model can be utilized as a simple diagnostic tool in case of the operational abnormality such as the hot spot which often occurs inside the stack.

    1996-12-31

    The conversion of methane into hydrogen for an MCFC by steam reforming is accomplished either externally or internally in the stack. In the case of external reforming the plant electrical efficiency is 5% abs. lower mainly because more parasitic power is required for air compression for stack cooling. Furthermore, heat produced in the stack must be transferred to the external reformer to drive the endothermic steam reforming reaction giving a more complex plant lay-out. A more suitable and cost effective approach is to use internal steam reforming of methane. Internal reforming may be accomplished either by Indirect Internal Reforming (DIR) and Direct Internal Reforming (DIR) in series or by DIR-only as illustrated. To avoid carbon formation in the anode compartment higher hydrocarbons in the feedstock are converted into hydrogen, methane and carbon oxides by reaction with steam in ail adiabatic prereformer upstream the fuel cell stack. This paper discusses key elements of the desire of both types of internal reforming and presents data from pilot plants with a combined total of more than 10,000 operating hours. The project is being carried out as part of the activities of the European MCFC Consortium ARGE.

  13. MCFC and microturbine power plant simulation

    The consistent problem of the CO 2 emissions and the necessity to find new energy sources, are motivating the scientific research to use high efficiency electric energy production's technologies that could exploit renewable energy sources too. The molten carbonate fuel cell (MCFC) due to its high efficiencies and low emissions seems a valid alternative to the traditional plant. Moreover, the high operating temperature and pressure give the possibility to use a turbine at the bottom of the cells to produce further energy, increasing therefore the plant's efficiencies. The basic idea using this two kind of technologies (MCFC and microturbine), is to recover, via the microturbine, the necessary power for the compressor, that otherwise would remove a consistent part of the MCFC power generated. The purpose of this work is to develop the necessary models to analyze different plant configurations. In particular, it was studied a plant composed of a MCFC 500 kW Ansaldo at the top of a microturbine 100 kW Turbec. To study this plant it was necessary to develop: (i) MCFC mathematical model, that starting from the geometrical and thermofluidodynamic parameter of the cell, analyze the electrochemical reaction and shift reaction that take part in it; (ii) plate reformer model, a particular compact reformer that exploit the heat obtained by a catalytic combustion of the anode and part of cathode exhausts to reform methane and steam; and (iii) microturbine-compressor model that describe the efficiency and pressure ratio of the two machines as a function of the mass flow and rotational regime. The models developed was developed in Fortran language and interfaced in Chemcad © to analyze the power plant thermodynamic behavior. The results show a possible plant configuration with high electrical and global efficiency (over 50 and 74%).

    The molten carbonate fuel cell (MCFC) is a promising option for highly efficient power generation possible to enlarge. IHI has been studying parallel flow MCFC stacks with internal manifolds that have a large electrode area of 1m{sup 2}. IHI will make two 250 kW stacks for MW plant, and has begun to make cell components for the plant. To improve the stability of stack, soft corrugated plate used in the separator has been developed, and a way of gathering current from stacks has been studied. The DC output potential of the plant being very high, the design of electric insulation will be very important. A 20 kW short stack test was conducted in 1995 FY to certificate some of the improvements and components of the MW plant. These activities are presented below.

  15. MCFC performance diagnosis by using the current-pulse method

    Several problems prevent molten carbonate fuel cells (MCFC) operation for an extended period. However, if the degradation factors can be identified and resolved in a timely manner, MCFC could become a valuable technology. Therefore, a performance diagnosis should be developed which enables the simple and instantaneous determination of MCFC degradation factors. A suitable six parameter equation obtained by a current-pulse method, obtainable from MCFC's transient response in 100 ms, is expressible in an equivalent circuit composed of three sub-circuits. The relationship between these parameters and each degradation factor is evaluated by a single MCFC cell, the electrode area of which is 16 cm 2. Degradation factors include cross-leakage, electrolytic loss, cell temperature distribution and gas composition/flow rate. As a result, each of six parameters in the MCFC transient response corresponds to an ohmic potential drop, anode/cathode gas diffusion resistance, reactive resistance, three-phase interfacial resistance and electrolyte properties, respectively. The proposed performance diagnosis specifies the degradation factors by combining the six parameters. Performance diagnosis was applied to a single MCFC cell of an electrode area of 81 cm in extended operations, and the degradation factor diagnosed. As a result, the diagnosis was able to specify the cell degradation factors from the degradation factor ratio, corresponding to cell voltage, cell resistance and the N 2 concentration of MCFC single cell performance. Therefore, the proposed performance diagnosis is able to easily specify the driven MCFC degradation factors in a timely manner.

    A 24-month effort in the development of a corrosion resistant hardware material for molten carbonate fuel cell (MFC) application is described. The objective was to identify an inexpensive alloy for MCFC current collector/bipolar plate application. For this, 310S was selected as the base alloy composition and La, Ce and Si were added to improve corrosion resistance. Eight candidate alloys, including 310S and 316L, were screened in MCFC anode and cathode atmospheres. The techniques used include isothermal corrosion, acoustic emission, thermal cycling corrosion, thermogravimetric analyses, electrical surface resistance, and dual atmosphere corrosion testing. Oxide scales formed were analyzed by standard metallographic techniques. The results indicate that COLT-25+ and Crutemp-25 alloys (both containing 25Cr-25Ni and balance Fe) have the best corrosion resistance in the MCFC environment. Rare earth additives, La and Ce, do not appear to improve isothermal or thermal cycling resistance. Silicon addition appears to improve thermal cycling but not isothermal corrosion resistance. High Mn content (approx. 18%) appears detrimental based on this limited investigation. Currently used 316L has the least corrosion resistance of all the alloys tested. Pressurized tests have shown that high pressure (10 atm) reduces corrosion rate in the anode atmosphere whereas it only slightly affects corrosion rate in the cathode atmosphere.

    The Molten Carbonate Fuel Cell (MCFC) is one of promising high efficiency power generation devices with low emission. Molten carbonate used for its electrolyte plays an important role in MCFC. It separates between anode and cathode gas environment and provides ionic conductivity on MCFC operation. Stainless steel is conventionally used as separator/current collector materials in MCFC cathode environment. As corrosion of the components of MCFC caused by the electrolyte proceeds with the electrolyte consumption, the corrosion in the MCFC is related to its performance and life. To understand and inhibit the corrosion in the MCFC is important to realize MCFC power generation system. We have studied the effect of alkaline earth carbonate addition into carbonate on corrosion of type 316L stainless steel. In this paper, we describe the effect of the temperature on corrosion behavior of type 316L stainless steel with carbonate mixture, (Li{sub 0.62}K{sub 0.38}){sub 2}CO{sub 3}, under the cathode environment in out-of-cell test.

    In the present work, the methods, techniques and results obtained during the studies of biomass fuelled molten carbonate fuel cell (MCFC) systems within the Swedish national fuel cell program are presented. The power plants are 60 MW class, utilising biomass (i.e. wood chips) as the primary fuel. The biomass is converted via pressurised gasification into a gaseous form that, after subsequent cleaning, can be used in the fuel cells. An investigation of the effects of gasification pressure, temperature and the influence of internal reforming on the overall system performance is presented.

    Similar to stand-alone ER-MCFC power systems industrial ammonia production facilities include hydrogen-rich synthesis-gas production. Therefore, integration of ER-MCFC stacks in a conventional industrial ammonia plant was investigated. By preliminary process design calculations three promising process structures were evaluated: (1) ER-MCFC is fed by the ammonia plant`s steam-reformer; anode off-gas to firing (2) similar to structure 1; in this case the anode off-gas is redirected to the ammonia process (3) ER-MCFC is fed by ammonia-synthesis purge gas The results indicate that for options 1 and 3 a return-on-investment for the ER-MCFC of around 8% is achievable at a stack cost of $250/kW and a revenue of 7c/kWh. Option 2 is not profitable, because of the associated reduction in ammonia production. The degree of hydrogen-utilization in the ER-MCFC to be selected for maximum profit varies with the process structure and indicates that there is scope for ER-MCFC stacks which operate at low hydrogen-utilization.

  20. Analysis and optimization of hybrid MCFC gas turbines plants

    Lunghi, Piero; Bove, Roberto; Desideri, Umberto

    High temperature fuel cells are electricity producers that guarantee relevant energetic and environmental performances. They feature high electricity to input chemical energy ratios and availability of high temperature heat. Notwithstanding, the search for a further increase in electric efficiency, especially when applying a CHP solution is not feasible, has brought to plant integration with gas turbines (GTs) in several studies and some pilot installations. While for pressurized fuel cells the choice of internal combustion gas turbines seem to be the only one feasible, in ambient pressure fuel cells it seems useful to analyze the combination with indirect heated GT. This choice allows to optimize turbine pressure ratio and cell size. In this work, a parametric performance evaluation of a hybrid molten carbonate fuel cell (MCFC) indirect heated gas turbine has been performed by varying the fuel cell section size and the fuel utilization coefficient. The analysis of performance variation with the latter parameter shows how a cell that is optimized for stand alone operation is not necessarily optimized for the integration in a hybrid cycle. Working with reduced utilization factors, in fact can reduce irreversible losses and does not necessarily yield to less electricity production since the heat produced in the post combustor is recovered by the gas turbine section. This aspect has not been taken into sufficient consideration in literature. The analysis illustrates the methodology to define new operating conditions so to allow global output and global efficiency maximization.

    The continuous increasing in biodiesel production by transesterification process is leading to an excess of glycerol production as a byproduct. The utilization of this huge amount of glycerol appears as a not easy solvable problem and thus several authors have proposed alternative ways. The integration of the main production process with a glycerol feed molten carbonate fuel cells bottoming cycle, to satisfy plant energy requirements, seems to be one of the most promising one. The proposed paper reports the main results obtained by authors in the framework of an investigation on a possible use of glycerol as energy sources for a real pilot plant for biodiesel production. An overall evaluation of worldwide biodiesel production plants was made and especially about the production capacity in European Union in the last decade. To make a more detailed study, authors were taken into account a real production plant. After a preliminary step, purported to plant mass and energy flows determination, authors considered the integration of a bottoming cycle based on: (i) steam reforming of glycerol for syn-gas production; (ii) molten carbonate fuel cells (MCFC) system supplied by syn-gas for heat and electricity production. A mathematical model, based on experimental data, has been developed to calculate mass and energy balances for the proposed plant lay-out as well as plant energy efficiency enhancement has been determined. Results have evidenced the feasibility of this process and demonstrated that plant integrated with bottoming cycle can reach a very high level of energy self-production.

At a temperature level of 650 C the MCFC incorporates all the advantages of high temperature fuel cells: internal reforming of hydrocarbons for simplest system design and highest efficiency and useful high temperature heat for industrial steam generation, without having to cope with the problems of ceramic fuel cell manufacturing.

    Multiple type structure of MCFC of which the separator of the cell is divided by four element cells has been studied. For the stable operation of this type cell, the effect of gas flow rate and temperature distribution on the cell voltage should be clear. In order to clarify these characteristics, a small sized mimic model has been made and tested. The flow rate distribution for the four element cells were varied and cell voltage and temperature distribution were measured for each cell. The decrease in cell voltage and the increase in maximum temperature became remarkable when the apparent utilization factor for one element cell became over 100%. The calculated results agreed fairly good with test results.

    The removal characteristics of CO 2 in molten carbonate fuel cell (MCFC) were elucidated by the single cell whose electrode area was 81 cm 2 and electrolyte was 52Li 2CO 3/48Na 2CO 3. The experimental value of the CO 2 removal rate from cathode to anode was almost corresponding to the theoretical value. Cell voltage dropped drastically when concentration of CO 2 in cathode became 15% or less. This tendency showed strikingly, as concentration of O 2 in cathode became lower and lower. The cell performance is influenced with the pO 2/ pCO 2 ratio of the cathode gases, because cell voltage decreases by decreasing the pO 2/ pCO 2 ratio. Therefore, when the pO 2/ pCO 2 ratio is as low as the thermal power plant, it is necessary to add air to cathode for improving the cell performance. Consequently, the reduction target of CO 2 in COP3 can be achieved.

    The molten carbonate fuel cell (MCFC) wet seal are has been found to experience accelerated corrosion in the presence of molten electrolyte because of simultaneous exposure to reducing and oxidizing atmospheres. Development of protective coatings plays an important role in minimizing this corrosion. Various aluminizing processes, such as flame spraying, slurry spraying, pack cementation, and ion vapor deposition, have been evaluated for their effectiveness. Continuous interdiffusion of aluminum and substrate Fe, Ni, and Cr occurred during high-temperature corrosion tests. Among the four aluminizing methods, ion-vapor deposition (IVD) with subsequent diffusion bonding appears to provide the most protective coating in the MCFC wet seal environment.

    1998-07-01

    Characteristics of heat transfer in Molten Carbonate Fuel Cells(MCFC) installed with offset-type fins are studied by using a fuel cell model consisting of electrodes, a perforated plate and a corrugated current collector. In this study the effect of several kinds of reacting gas on heat transfer characteristics is elucidated by measuring gas and surface temperatures, gas species composition, cell components and vertical heat flux. As a result, Wieting's equation to evaluate heat transfer characteristics in heat exchangers is not appropriate to the MCFC since Reynolds number in operating the MCFC is far less than the applicable range of the equation. Most of the vertical heat flux is controlled by heat conduction in the cell components. The convective heat transfer coefficient depends on kinds of gas species rather than the gas flow rate. Thermal properties affect the convective heat transfer coefficient. Especially, the vertical heat flux increases with an increase of H{sub 2} concentration. The obtained fundamental results can elucidate phenomena of heat transfer in practical MCFC appropriately.

    To prolong the life of cell is one of the most important issues for MCFC to be brought into actual application. In this respect, investigators have been proposing the addition of tungstate salt such as K2WO4 into MCFC electrolyte, which is supposed effectively to reduce the sintering of anode probably by precipitates formed through the reduction of tungstate with dissolved hydrogen near the anode surface. In this research, such effect upon sintering of anode was quantitatively examined by out-of-cell tests and the validity of above assumption for the mechanism was confirmed. Also other effects of tungstate salt addition into electrolyte, such upon corrosion of separator, solubility of cathode, stability of matrix substrates (LiAlO{sub 2}) were investigated.

    1996-12-31

    Long term operation is an essential subject in the commercialization of the Molten Carbonate Fuel Cell (MCFC). Material stability is important for the development of the MCFC. particularly for long term operation. In this paper, the specification and the stabilization of MCFC matrix arc investigated, with the aim of producing 40000 hours of operation. It is common knowledge that matrix thickness has a large influence on shorting time, as shorting is caused by the dissolution of the nickel oxide cathodes. Therefore, the optimum thickness of a matrix designed for 40000 hours operation without the nickel shorting was sought. The influences of different electrolytes and matrix specifications on the shorting time were measured with accelerated cell tests. The internal resistance of the matrix was also estimated. Gamma( {gamma} )-lithium aluminate (LiAlO{sub 2}) powder with a sub-micron particle diameter is commonly used for a raw material of matrix to retain molten carbonate electrolytes. This is because most researchers found that {gamma}-LiA1O{sub 2} was the most stable material in the MCFC environment among the three allotropic forms alpha ( {alpha} ), beta ( {beta} ), and {gamma}. However. two problems with the stability of {gamma} -LiAlO{sub 2} are being vigorously discussed. especially in Japan: particle growth causes decreasing electrolyte retention, and the transformation of {gamma} to {alpha}. This transformation contradicts the accepted opinion that {gamma} is the most stable form. In this paper, the particle growth and the phase transformation of LiAlO{sub 2} are examined with post-test analyses. The influence of matrix degradation on cell performance is also considered.

  13. Wide range load controllable MCFC cycle with pressure swing operation

    NASA Astrophysics Data System (ADS)

    Yoshiba, Fumihiko; Izaki, Yoshiyuki; Watanabe, Takao

    Partial load efficiencies of a natural gas fuelled MCFC/GT system are calculated; the efficiencies of four systems are compared. A constant pressure air compressor is applied in system cases 1 and 2, whereas a pressure swing air compressor is provided in system cases 3 and 4. A gas cooler is integrated in the cathode gas recycling line of cases 2-4, and an anode recycling with sub-reformer is provided in case 4. The cathode pressure loss in the MCFC stack is kept below 3 kPa during the calculation procedure to avoid a leakage of cathode gas. The range of the power load is limited to 50-100% in the constant operating pressure system (cases 1 and 2), mainly because of the limited cathode gas pressure loss of 3 kPa. The range of the power load is enlarged to 20-100% in cases 3 and 4 by combining the pressure swing operation with gas cooling in the cathode recycling line. In system cases 3 and 4, the efficiency at the lowest load operation (approx. 20-30% load) remains over 35% HHV-CH 4, whereas the maximum efficiency is calculated to be 53% HHV-CH 4 in middle load operation; the efficiency of case 4 at 100% load is estimated to be 50% HHV-CH 4. The combination of the pressure swing operation and gas cooling in the cathode recycling line offers a high efficiency of the MCFC system in a wide range of loads.

    This project aims to identify the long-term endurance problems of the MCFC by investigating corrosion of stainless steel (310, 316L). This presentation focuses on results from SEM and cross-section analysis. Significant differences between immersed and film-wetted electrodes are summarized. Results suggest that pre-oxidation can be a solution to obtaining a compact oxide layer. Adding Al to alloy leads to a very stable oxide layer, but increases resistivity. Alloy behavior must be investigated under continuously polarized conditions. 4 figs.

    M-C Power Corporation`s (MCP) mission is to commercialize molten carbonate fuel cell (MCFC) power plants based on an internally manifolded IMHEX stack concept patented by the Institute of Gas Technology. MCP has successfully scaled up the manufacturing and design of the MCFC technology to commercial area (1-m{sup 2}). Five commercial-area 20-kW stacks and two commercial-area 250-kW stack have been built and operated. A third commercial (250-kW) stack is being assembled. Continuous process improvements and yield increases have been demonstrated for the manufacturing run for each successive 250-kW stack. These improvements resulted in a 63% reduction in the cost of the active area components from the first to the third 250-kW stack. Concurrent with the production and testing of commercial-area fuel cell stacks, M-C Power has an ongoing effort to develop, test, and scale-up to commercial-area advanced component technologies that will enable M-C Power to meet cost and performance, and endurance goals. This effort focuses on developing lower cost stack components with improved endurance and performance and evaluating alternate manufacturing procedures and raw materials which significantly lower the stack costs. Following performance verification at the bench scale level, scale-up of the advanced component manufacturing processes to commercial-area has been ongoing in the past year.

In this project participate: Brandstofcel Nederland BV (BCN), British Gas pic (BG), Gaz de France (GDF), Netherlands Energy Research foundation (ECN), Stork, Royal Schelde and Sydkraft AB. The European Fuel Cell User Group (EFCUG) supports the project as an advisory board. Whereas the US and Japanese programmes are aimed at large-scale demonstrations of the MCFC technology, this project focusses on the development of concepts and technology, required for MCFC systems that will be competative on the cogeneration market.

    Performance modeling studies are a necessary and cost effective element of the IMHEX-MCFC stack commercialization. Technologix Corporation, in cooperation with M-C Power, has developed the algorithms and computer code for two of the models in addition to modifying the PSI model for applications specific to IMHEX fuel cell concept. Three performance models support the product development effort: a modified PSI model; a two-dimensional cross-flow cell model and a three-dimensional stack model. The sizing, number and location of the stack inter-coolers in a fuel cell stack are typical model application. Recently M-C Power modified its stack configuration to cross-flow. The cross-flow allows simplified repeat parts manufacturing and reduces the risk of gas crossover. The MCFC cross-flow model developed at M-C Power supports heat loss from the stack edges, variable fuel flow rate regions and variable oxidant flow rate regions (coupled with the optimization module) among other features. Extensive computational experiments were conducted in support of the cross-flow geometry development for the MCFC stack. The oxidant flow distribution optimization was used to mitigate the hardware temperature hot-spot typical for the cross-flow geometry. The hardware temperature hot-spot increases corrosion rate, electrolyte loss, and leads to deterioration of the long-term MCFC stack performance. Under the normal operating conditions, the maximum local temperature of the cell hardware should not exceed 960 K. The mathematical optimization software was applied to find the optimum flow distribution. The minimization of the maximum hardware temperature was defined as an optimization goal. The gas flow rate in each region was selected as independent variable subjected to optimization. In some cases the authors have also added a distance between the fuel inlet and the flow region divider to the list of independent variables.

    The emphasis of this project is to develop new, conductive ceramic materials and to produce structures from these materials for use as the components in the molten carbonate fuel cell (MCFC). The components under study include the cathode, anode, and interconnect, each of which is at a different stage of development. The cathode work focuses on assessing the viability of LiFeO{sub 2} as a replacement for the state-of-the-art NiO; this assessment relies on cell testing, with the performance data serving as the bases for component improvement. The anode studies seek to develop the required conductivity in a stable compound that exhibits little sensitivity to the range of anode oxygen partial pressures; this can be achieved through doping. The interconnect work emphasizes determining the effect of fuel and oxidant on conductivity, material properties, and structural integrity. 4 refs., 4 figs.

    Fuel cell power plant has been developed for many years with expectation of high system efficiency. In the meantime the gas turbine combined cycle has shown its considerable progress in improving system efficiency. Fuel cell power plant will no longer be attractive unless it exceeds the gas turbine combined cycle at least in the system efficiency. It is said CO{sub 2} separation could improve the efficiency of fuel cell power plant. IHI has developed the CO{sub 2} separator for fuel cell power plant.

  5. Molten carbonate fuel cells (MCFC): Structure and operation

    SciTech Connect

    1996-03-01

    The main components of an individual cell are the anode, the cathode, and the molten carbonate electrolyte. Electrode materials are usually porous nickel alloys for reducing atmospheres (anode) and nickel oxide for oxidizing atmospheres (cathode). The electrolyte, typically a combination of molten, alkali (Li, K, Na) carbonates, is contained within a porous ceramic matrix, commonly made of lithium aluminate (LiAlO{sub 2}). The molten carbonate electrolyte, sandwiched between the anode and cathode, partially fills these porous electrodes. Electrochemical reactions take place at a three-phase interface formed by the electrolyte, the electrodes, and the gas streams. Carbonate ions are formed at an oxidant/electrolyte interface in the cathode and are transported through the electrolyte to a fuel/electrolyte interface in the anode. There, the carbonate ions react with the fuel, releasing electrons into the anode. The electrons then travel through an external circuit and through the load, suffering a voltage drop. Finally, the circuit is completed as the electrons return to the cathode. The paper gives data on MCFC efficiency and NO{sub x} emissions compared with engines and turbines.

  6. Effects of system configuration and operating condition on MCFC system efficiency

    A process simulation model of an externally reformed molten carbonate fuel cell (MCFC) system is used to analyze quantitatively parametric effects on system efficiency. In order to verify the MCFC process simulation model, a 25 kW system is analyzed on the basis of experimental data and its calculated efficiency is found to be reasonable. The overall system efficiency of a high-temperature fuel cell system, especially a MCFC, cannot be increased without proper thermal integration between the heat recovery units and without additional power from auxiliary power generation units such as turbines. The results of the simulation show that the configuration of the unit operators in a given system has a great effect on system efficiency, while system size and operating conditions have slightly less effects. Based on the system configuration, the optimal operating conditions (including fuel, oxidant utilization, and recycle ratio) can be specified to maximize the system efficiency.

    Cathode dissolution into the electrolyte matrix and endurance of current collector/separator plate materials are the main life-limiting factors of the state-of-the art MCFC. These components are also major contributors to the total system cost. Therefore, to reduce capital cost, it is necessary to minimize hardware corrosion and increase cell life. This study consists of experimental evaluation of corrosion processes with the objective to further practical; understanding of corrosion behavior of alloys and alloy components under cathodic gas conditions. Nickel, iron, cobalt and stainless steels 310 and 316L are analyzed. The experimental study consists of (1) Observation of open circuit potential (OCP) changes. Surface reactions occurring without net passage of current are proposed based on this measurement. (2) Applying cyclic voltammetry, which provides information about the possible electrode reactions at different stages of polarization. (3) Applying AC impedance to support the result of tasks 1 and 2 at different stages of oxidation, and data analysis by means of equivalent circuits. Open circuit conditions as well as positive and negative polarization are used in the impedance measurements. (4) Surface analysis of the electrodes by SEM-EDX and X-ray diffraction. To obtain more information from electrochemical measurements a novel approach has been applied in cell design. In this two-electrode approach, one electrode is fully immersed, and the other is wetted by carbonate melt via an alumina tube which has a thin film on it. While camera observation of these two different electrode conditions will identify the effect of carbonate wetting on the state of the surface, electrochemical measurements enable a quantitative comparison between complete submersion and wetting by a film of carbonate.

    Biogas recovery is an environmentally friendly and cost-effective practice that is getting consensus in both the scientific and industrial community, as the growing number of projects demonstrate. The use of fuel cells as energy conversion systems increases the conversion efficiency, as well as the environmental benefits. Molten carbonate fuel cells (MCFC) operate at a temperature of about 650 °C, thus presenting a high fuel flexibility, compared to low temperature fuel cells. Aim of the present study is to compare the performance of an MCFC single cell, fuelled with different biogas types as well as methane. The biogases considered are derived from the following processes: (1) steam gasification in an entrained flow gasifier; (2) steam gasification in a duel interconnect fluidized bed gasifier; (3) biogas from an anaerobic digestion process. The performances are evaluated for different fuel utilization and current densities. The results are an essential starting point for a complete system design and demonstration.

    H 2 production by ethanol steam reforming in simulating molten carbonate fuel cell (MCFC) conditions was explored. Ni/MgO catalysts exhibit very high selectivity to H 2 and CO 2 as a consequence of their low tendency to promote carbon monoxide methanation and ethanol decomposition reactions. Coke formation is strongly depressed due to the benefits induced by the use of basic carrier which positively modify the electronic properties of supported Ni.

    Fuel cells technologies for stationary applications are expected to play a remarkable role in the field of next decade energy production systems ranging from some hundreds kW to some MW. The interest in using fuel cells to produce electric energy comes from the advantages that fuel cells offer in terms of high efficiency, good behavior at base and partial load, very low emissions, modularity (easy adjustment of plant capacity to power-demand increase), and reduced time to be spent for plant erection. At least four types of fuel cells can be considered suitable for stationary applications. With reference to their electrolyte they can be classified as: Polymeric Electrolyte Membrane Fuel Cells (PEMFC), Phosphoric Acid Fuel Cells (PAFC), Molten Carbonate Fuel Cells (MCFC) and Solid Oxide Fuel Cells (SOFC). Each of them works at a temperature level that is depending on the type of electrolyte. From a general point of view all the fuel cell technologies present, at various extents, the above listed advantages. Nevertheless specific features of each fuel cell type suggest to identify a specific field of application for each type of solution, in order to stress the potential advantages of any technology and minimize its possible drawbacks. Anyway the different level of maturity for the various fuel cell technologies does not allow an homogeneous comparison of technical and economical key parameters. PAFCs, due to their present commercial availability and operation experience, are well outlined in terms of performance and costs; on the contrary with regard to the other technologies--PEMFC, MCFC and SOFC--which are still under development, their commercialization is expected within a period of 7 to 13 years according to single technology maturity level (MCFC level seems to be more ready), kind of application, competitors, environmental constraints, etc.

  16. Endurance test on a single cell of a novel cathode material for MCFC

    The molten carbonate fuel cell (MCFC) is expected to be an efficient device for the conversion of chemical energy in the near future. However, one of the major limits to the lifetime is the dissolution of the nickel oxide cathode in the electrolyte. This problem can be overcome by the addition of new compounds to the nickel oxide. In this way, the performance and the endurance of a new Ni-Ce cathode for MCFC has been tested and the results compared to a commercial nickel cathode. The polarisation curves were measured in order to check the degradation of the cell performance with time. The results showed a better performance with the novel cathode material (136 mW/cm 2 at 200 mA/cm 2 during 2100 h) than the commercial one (the voltage decreased from 120 to 108 mW/cm 2 at 150 mA/cm 2 in 1000 h). The better performance of Ni-Ce cathode with respect to the Ni one can be attributed to the good effect of cerium in the cathode. The change in the nickel crystalline structure reduces the dissolution of nickel in the electrolyte and implies a greater endurance of the cell. The current-voltage curves were measured and showed the same trend for both cells. Postmortem analyses were done in order to characterise the cells. As a conclusion, the addition of cerium can be beneficial to overcome the dissolution of the nickel cathode in the electrolyte, which is considered one of the major limits to the lifetime of a MCFC.

    A fuel cell life time and its correct working are strongly dependent on its main components characteristics: anode, cathode and matrix. The required performances are directly correlated to two very important parameters: porosity and average pore diameter. In particular the influence of raw powders on MCFC anode porosimetric properties was studied. Ni-Al spherical and non-spherical powders were tested for anode production and the final samples were analysed by mercury porosimetry, scanning electron microscopy (SEM-EDS) and X-ray.

    The stability of the NiO cathodes in molten carbonate fuel cell (MCFC) has been improved through microencapsulation of the NiO cathode with nanostructured Co. Cobalt was deposited on the NiO cathode using an electroless deposition process. The electrochemical oxidation behavior of the Co-coated electrodes is similar to that of the bare NiO cathode. The cobalt-coated electrodes have a lower solubility in the molten carbonate melt when compared to bare nickel oxide electrodes in the presence of cathode gas. The solubility decreased more than 50% due to microencapsulation with cobalt. The thermal oxidation rate was also lower in case of the cobalt-encapsulated electrode. Impedance data from the modified electrode indicate that the oxygen reduction reaction depended inversely on the CO 2 and directly on the oxygen partial pressures respectively suggesting a similar reaction mechanism to that of nickel oxide. The results indicated that cobalt-encapsulated NiO is a viable solution in the development of alternate cathodes for MCFC applications.

    The molten carbonate fuel cells (MCFC), as an alternative power source, present one of the most promising and environmental cleanest processes. As a high temperature fuel cell, problems arise due to corrosion of the metallic current collectors and voltage drop by formation of insulating corrosion products. The aim of this work is to develop Fe-Cr stainless steels, alloyed with different amounts of Mn, Co, Si, Ni, Mo, in order to obtain an acceptable thin corrosion scale with a low electrical resistivity by spinel formation. The formation of spinel layers as corrosion products, containing multivalent elements like Mn, Co and Mo is expected to give satisfactory results. In situ conductivity measurements and corrosion tests have been performed in the presence of a (Li, K) carbonate melt at 650 °C under an oxidizing gas atmosphere (15 vol.% CO 2 and synthetic air) up to 5000 h. Investigations of the corrosion scales on the hot rolled alloys indicated a solubility of Co and Mn in the spinel layer, formed under the simulated MCFC conditions. Outward diffusion of Mn and Co was observed after longer reaction times. An inner oxidation zone was also measured and connection between conductivity behaviour and the composition of this layers is found.

These oxides are stable thermodynamically whatever the cathode or anode gaseous conditions. Good quality, dense and homogeneous coatings were obtained at thicknesses lower than 1 μm. The structure of the deposits, as analysed by XRD, was the expected one. In this work only dense nickel substrates were used. After their direct immersion in a Li 2CO 3-Na 2CO 3 carbonate eutectic at 650 °C, which can be considered as extremely corrosive conditions with respect to the usual MCFC conditions, the coatings were affected. TiO 2 coatings were transformed into Li 2TiO 3, in agreement with thermodynamic predictions; however, they became progressively unstable, which was probably due to a problem of mechanical adhesion rather than to solubility. The thinner was the deposit, the higher was its conductance and the closer to that of a pure Ni electrode was its electrocatalytic activity. CeO 2 coatings were stable in a ceria form and their adhesion was better even though not fully satisfactory. These first preliminary results are promising regarding the direct contact of the coatings with the corrosive carbonate melt, but the improvement of the adhesion is one of the major problems to solve.

    Porous nickel cathode was protected by potentiostatically deposited cobalt at different experimental conditions: oxidation potential and electrolysis duration. The deposition growth increased with the oxidation potential yielding a more developed granular structure with smaller grains. Thin layers of Co 3O 4 were identified by X-ray diffraction (XRD) and Raman spectroscopy. CoOOH was detected by X-ray photoelectron spectroscopy (XPS) before annealing treatment and Co 3O 4 after heating the sample at 500 °C during 4 h in air. After this treatment, some morphological changes were observed on the coated samples due to grain compaction and oxidation of the nickel substrate. The porosity of the coated samples was relatively close to that of the sole porous nickel. These coatings exhibited an appropriate dual-pore structure with macro and micro pores, a basic MCFC requirement.

    Physical Sciences Inc. has performed a preliminary evaluation of the effects of soot control measures on the molten carbonate fuel cell powerplant. Soot control measures are required because of the temperature and humidity restrictions imposed on the system by the low temperature gas cleanup system. The system configuration chosen is the General Electric System 1 configuration. This system uses a Texaco, oxygen blown gasifier and a low temperature (Selexol) gas cleanup system. The pressure of this portion of the system is about 600 psi which drops to 500 psi at the exit of the gas cleanup system. The gas which at this point has dew point of 100/sup 0/F is expanded to about 105 psi. At this point, steam is injected. The function of this steam is to suppress soot formation both in the anode inlet preheater and in the molten carbonate fuel cell (MCFC) anode. GE alludes that the function of the steam may also be to optimize the output of the steam turbines. Upon leaving the anode, the sensible heat in the anode exhaust is used to regeneratively preheat the anode inlet gas. Finally, the anode exhaust is fed to a catalytic combustor via a compressor. The combustor effluent is mixed with fresh cathode inlet air. This stream is then mixed with cathode exhaust recycle. The resulting mixture is fed to the MCFC cathode. The cathode exhaust is split into recycle and system exhaust streams. About 77% of the cathode exhaust is recycled. The system exhaust is expanded through a gas turbine, a regenerative heat exchanger and an economizer. Results of the study are reported. (WHK)

  4. Optimum operating conditions of DIR-MCFC without vapor-phase carbonate pollution

    In direct internal reforming-molten carbonate fuel cells (DIR-MCFC), deterioration of catalytic activity takes place in the anode channel due to both liquid-phase pollution and vapor-phase pollution. Although the liquid-phase pollution can be solved by installing protective barrier, an effective defense method and a reactivation method of vapor-phase polluted catalyst have not established yet. In order to study the reactivation method, the adhesion form of potassium compounds in the polluted catalyst under the various gas conditions was evaluated by using a thermogravimetric analyzer in which water vapor can feed. Additionally, the activity of the treated catalyst was also tested by a differential reactor. As a result, KOH changes to K 2CO 3 under a CO 2 concentration of 25% or more. KOH becomes a solid-phase from the liquid-phase when it is changed into K 2CO 3. Therefore, the catalyst can not be reactive because K 2CO 3 chokes pores of the catalyst. However, the activity of the polluted catalyst is revived to 80% of the initial activity by controlling the gas species concentration, especially CO 2. Moreover, the catalytic activity can be revived under a steam-carbon ratio of 2.0 or more. Based on the results obtained by these fundamental experiments, the reactivation methods of catalyst polluted are proposed as follows: (i) catalyst should be loaded more upstream in the anode; (ii) in order to reactivate the polluted catalyst, the DIR-MCFC should maintain a steam-carbon ratio of 2.0 or more; (iii) gas conditions to activate the catalyst should be applied regularly.

    The molten carbonate fuel cell (MCFC) uses generally mixture of lithium carbonate and potassium carbonate (Li/K) as the electrolyte. NiO cathode dissolution is one of serious problems for MCFC life. The NiO cathode has been found to dissolve into the electrolyte as Ni{sup 2+} ion which is reduced to metallic Ni by H{sub 2} in the fuel gas and bridges the anode and the cathode. The bridges short circuit and degrade cell performance and shorten cell life. Since solubility of NiO in mixture of lithium carbonate and sodium carbonate (Li/Na) is lower than in Li/K, it takes longer time to take place slowing by NiO cathode dissolution in Li/Na compared with in Li/K. The ionic conductivity of Li/Na is higher than of Li/K, however, oxygen solubility in Li/Na is lower 9 than in Li/K. A new 10 kW class MCFC stack composed of Li/K cells and Li/Na cells, was tested. Basic performance of the Li/K cells and Li/Na cells of the stack was reported.

    The MTU MCFC program is carried out by a European consortium comprising the German companies MTU Friedrichshafen GmbH, Ruhrgas AG and RWE Energie AG as well as the Danish company Energi E2 S/A. MTU acts as consortium leader. The company shares a license and technology exchange agreement with Fuel Cell Energy Inc., Danbury, CT, USA (formerly Energy Research Corp., ERC). The program was started in 1990 and covers a period of about 10 years. The highlights of this program to date are: Considerable improvements regarding component stability have been demonstrated on laboratory scale. Manufacturing technology has been developed to a point which enables the consortium to fabricate the porous components on a 250 cm 2 scale. Several large area stacks with 5000-7660 cm 2 cell area and a power range of 3-10 kW have been tested at the facilities in Munich (Germany) and Kyndby (Denmark). These stacks have been supplied by FCE. As far as the system design is concerned it was soon realized that conventional systems do not hold the promise for competitive power plants. A system analysis led to the conclusion that a new innovative design approach is required. As a result the "Hot Module" system was developed by the consortium. A Hot Module combines all the components of a MCFC system operating at the similar temperatures and pressures into a common thermally insulated vessel. In August 1997 the consortium started its first full size Hot Module MCFC test plant at the facilities of Ruhrgas AG in Dorsten, Germany. The stack was assembled in Munich using 292 cell packages purchased from FCE. The plant is based on the consortium's unique and proprietary "Hot Module" concept. It operates on pipeline natural gas and was grid connected on 16 August 1997. After a total of 1500 h of operation, the plant was intentionally shut down in a controlled manner in April 1998 for post-test analysis. The Hot Module system concept has demonstrated its functionality. The safety concept has been

  8. Factor Study for the Separator Plate of Mcfc Having Uniform Stiffness at Elevated Temperature

    A molten carbonate fuel cell (MCFC) is composed of several stacks of unit cells. A unit cell is composed of two electrodes and a matrix that is inserted between separator plates. Separator plates should properly contact the electrodes to reduce the electricity loss arising from contact resistance. To this end, a pressure of about 2 kgf/cm2 is usually applied on the top of the stack, which results in the separator plates being somewhat compacted. Furthermore, the stiffness of the separator plates becomes degraded at elevated temperatures due to softening of the plate materials. Therefore, a nonuniform temperature distribution across the separator plates induced by exothermic reactions of the oxidant and reactant gases leads to a non-uniform plate stiffness. This study has firstly evaluated the change in separator plate stiffness as temperature changes by applying pressure to the plates. Secondly, using the Taguchi method, several design factors that affect stiffness have been investigated to determine which has the most influence. Based on these results, a new design for the separators, which allows for uniform stiffness at elevated temperatures, has been proposed.

    Cobalt substituted lithium-nickel oxides were synthesized by a solid-state reaction procedure using lithium nitrate, nickel hydroxide and cobalt oxalate precursor and were characterized as cathodes for molten carbonate fuel cell (MCFC). LiNi 0.8Co 0.2O 2 cathodes were prepared using non-aqueous tape casting technique followed by sintering in air. The X-ray diffraction (XRD) analysis of sintered LiNi 1- xCo xO 2 indicated that lithium evaporation occurs during heating. The lithium loss decreases with an increase of the cobalt content in the mixed oxides. The stability studies showed that dissolution of nickel into the molten carbonate melt is smaller in the case of LiNi 1- xCo xO 2 cathodes compared to the dissolution values reported in the literature for state-of-the-art NiO. Pore volume analysis of the sintered electrode indicated a mean pore size of 3 μm and a porosity of 40%. A current density of 160 mA/cm 2 was observed when LiNi 0.8Co 0.2O 2 cathodes were polarized at 140 mV. The electrochemical impedance spectroscopy (EIS) studies done on LiNi 0.8Co 0.2O 2 cathodes under different gas conditions indicated that the rate of the cathodic discharge reaction depends on the O 2 and CO 2 partial pressures.

    To improve the mechanical properties of MCFC cathode materials, pre-lithiated porous nickel plates containing 1-5 mol% of lithium were fabricated by the tape casting method, and the microstructures, mechanical properties, and performance was examined. The microstructure and pore distribution was not changed until the lithum content reached 3 mol%. The sample containing 5 mol% of lithium had patch structure on the skeleton and a smaller volume of primary pores. XRD analysis showed that lithium-containing porous nickel plates can easily form solid solutions without any undesirable byproducts after the oxidation. Both the bending strength and Young's modulus of the porous plates increased with the increase of lithium content. The average bending strengths of the samples containing 1, 3, and 5 mol% of lithium were 1.29, 1.33, and 1.49 kgf/mm 2 which were 2.9, 3.0, and 3.4 times higher than that of pure porous nickel plate. The Young's modulus increased up to 1.35 kgf/mm in the case of the 5 mol% lithium containing sample that is 5.4 times higher than that of pure porous nickel plate. The OCV of single cells using pre-lithiated cathodes were between 1.065 and 1.067 V, and comparable cell performance was obtained for 500 h of single cell operation.

    Despite many advantages of the direct internal reforming molten carbonate fuel cell (DIR-MCFC) in producing electricity, there are many problems to solve before practical use. The deactivation of reforming catalyst by alkali like lithium is one of the major obstacles to overcome. A promising method is addition of TiO 2 into the Ni/MgO reforming catalyst, which resulted in the increased resistance to lithium poisoning as we previously reported. To understand how added titania worked, it is necessary to elucidate the deactivation mechanism of the catalysts supported on metal oxides such as MgO and MgO-TiO 2 composite oxide. Several supported nickel catalysts deactivated by lithium carbonate were prepared, characterized and evaluated. The Ni/MgO catalyst turned out to be most vulnerable to lithium deactivation among the employed catalysts. The activity of the Ni/MgO gradually decreased to zero with increasing amount of lithium addition. Deactivation by lithium addition resulted from the decrease of active site due to sintering of nickel particles as well as the formation of the Li yNi xMg 1- x- yO ternary solid solution. These were evidenced by H 2 chemisorption, temperature programmed reduction, and XRD analyses. As an effort to minimize Li-poisoning, titanium was introduced to MgO support. This resulted in the formation of Ni/Mg 2TiO 4, which seemed to increase resistance against Li-poisoning.

    Six years ago, M-C Power (MCP) developed a comprehensive business plan to commercialize molten carbonate fuel cell (MCFC) power plants. On an annual basis the plan has been reviewed and modified to adapt to identified end user needs and technological advancements. As a result, product definition kept abreast with marketing requirements. Over the last five years, there was order and reason for subtle shifts in supply, demand, competition and pricing policies. Today, however, traditional market assessment assumptions must be challenged. There is a revolution taking place. The revolution can be summed up in one word ... deregulation. Deregulation of the airline industry led to consideration of the natural gas industry. Now that natural gas deregulation is behind us, it is electric power and telecommunications that are receiving attention. Increased emphasis is being placed on achieving market-priced power. The net result will be thinner margins for the seller and the end user. What does this mean for the commercialization of molten carbonate fuel cells?

    Earlier electrolyte segregation tests of Li/Na carbonate used chemical analysis such as inductively coupled plasma/atomic emission spectroscopy (ICP/AES) of matrix strips wetted with carbonate and exposed to 5- to 20-V potential gradients. A segregation factor was correlated to the Li/Na carbonate composition. While fairly substantial segregation occurs at the eutectic composition of 52% Li, it is minimal at 60% to 75% Li. Such lithium-rich Li/Na carbonates may not be practical because the melting points are too high (i.e., liquidus point is 625 C). By adding calcium and barium to the lithium/sodium carbonates, we were able to lower the melting point and maintain nonsegregating behavior. This work is directed at examining the long-term stability of the quaternary Li/Na/Ba/Ca electrolytes. Electrolyte optimization work evaluates Li/Na ratio and Ba/Ca level to improve cell performance at 320 mA/cm{sup 2} and reduce temperature sensitivity. A number of cells with quaternary Li/Na/Ba/Ca electrolytes ranging from 3 to 5% Ba/Ca have operated well with stable, long-term performance. Congruent melting carbonate is important for commercial development. The best so far is 3.5% Ba/Ca/Na/Li (3.5 mol%/3.5 mol% Ba/Ca) carbonate (m.p. 440 C). Performance at 160 mA/cm{sup 2} is increased up to 150mV as compared with the baseline cell containing the Li/Na eutectic composition. Life stability has been reproduced by a number of bench-scale MCFC test with operations of 2000-4300 h and the electrolyte composition across the matrix little changed.

    M-C Power Corporation (MCP) was founded in 1987 to commercialize Molten Carbonate Fuel Cell (MCFC) stacks. The first generation of active area cell components were successfully scaled-up from the 100-cm{sup 2} area laboratory scale to continuous production of commercial-area (1-m) components. These components have been tested in five commercial-area subscale (20-kW) stacks and one commercial-scale (250-kW) stack. The second 250 kW stack is being installed in the power plant for operation in late 1996 and components have already been manufactured for the third 250-kW stack which is scheduled to go on-line in the middle of 1997. Concurrent with commercial-area (1-m{sup 2}) active component manufacturing has been an ongoing effort to develop and test advanced component technologies that will enable MCP to meet its future cost and performance goals. The primary goal is to lower the total cell package cost, while attaining improvements in cell performance and endurance. This work is being completed through analysis of the cost drivers for raw materials and manufacturing techniques. A program is in place to verify the performance of the lower cost materials through pressurized (3 atm) bench scale (100-cm{sup 2}) cell tests. Bench-scale cell testing of advanced active area components has shown that simultaneous cost reduction and improvements in the performance and endurance are attainable. Following performance verification at the bench scale level, scale-up of the advanced component manufacturing processes to commercial-area has been ongoing in the past year. The following sections discuss some of the performance improvements and reductions in cost that have been realized.

    The possibility of introducing a co-generation system with a direct internal reforming-molten carbonate fuel cell (DIR-MCFC) for residential use is examined by a feasibility study. First, the structure of a system, which can maintain the cell temperature (650 °C) without the heat supply, is constructed by calculating heat and material balances among the system components. Secondly, a model family, which might use the co-generation system with a DIR-MCFC, is constructed from the results of a questionnaire on room layout, number of family members, and the number of electric appliances and consumption of electric power in Osaka. Thirdly, calculating the electric power and hot-water demand supply balance optimizes the scale of the co-generation system with a DIR-MCFC for residential use. Finally, the running costs of this optimum system using city gas or propane gas are considered. As a result, the optimum scale of a co-generation system a with DIR-MCFC and using city gas is 3 kW, while it is 6 kW for the case using propane gas. The co-generation system using city gas is suitable for a house. On the other hand, the system using propane gas is suitable for an apartment.

    The metallic bipolar plates of a molten carbonate fuel cell (MCFC) consist of a shielded slot plate and a center plate. Among these, the shielded slot plate (the current collector) supports the Membrane Electrode Assembly (MEA) mechanically. The anode gases and the cathode gases pass through a space between individual slot patterns. The catalysts are located in the upper part of the shielded slot plate. Therefore, triple phase boundaries can be generated, and carbonate ions can act as the mobile charge carrier for the MCFC. Due to these properties, the shielded slot plate should have a sheared corrugated pattern. In order to form a sheared corrugated pattern, a slitting process is required during the first stage of the forming process. However, it is not possible to obtain a high aspect ratio in a sheared corrugated trapezoidal pattern due to the plastic strain concentration on the upper round region of the pattern. Therefore additional forming processes are required to form a high aspect-ratio pattern. For example, the two additional processes such as a "stretching process using a preform" and a "final forming process" can be done subsequent to the first slitting process. Before the final forming process, a stretching process, which forms an intermediate shape (perform), can make the strain distribution more uniform. Hence, various examples of performs were evaluated by using FEM simulation employing simplified boundary conditions. Finally, experiments involving microscopic and macroscopic observations using the proposed shape of a preform were conducted to characterize the formability of the sheared corrugated pattern. It was found that the numerical simulations are in good agreement with the experimental results.

    To establish high performance of MCFC, a new high corrosion resistant alloy (30%Cr-45%Ni-1 %Al-0.03%Y-Fe) for MCFC separator has been developed. The developed alloy has good corrosion resistance for both anode and cathode environments. On the other hand, one of the main factors to determine the life time of MCFC stack is electrolyte loss. A potential danger of electrolyte loss cased by corrosion of metal components is pointed out. Basic mechanism of electrolyte loss is proposed according to following reactions. High Cr content alloy such as type 310S(25%Cr-20%Ni) has disadvantages in view of electrolyte loss in spite of high corrosion resistance. It is said that the dissolution of Cr ion into electrolyte is detrimental for electrolyte loss, because a mole of CrO{sub 4}{sup 2+} ion combines 2 moles of K{sup +} ions as K{sub 2}CrO{sub 4}, while a mole of Fe{sup 3+} ion combine a mole of Li{sup +} ion as LiFeO{sub 2}. To understand the mechanism of electrolyte loss due to corrosion of metal component, the distribution of metal ions in oxide and molten salt were studied.

    The shielded slot plate, which has a sheared corrugated trapezoidal pattern, is a component of the metallic bipolar plate for the molten carbonate fuel cell (MCFC). In order to increase the efficiency of the fuel cell, the unit cell of the shielded slot plate should have a relatively large upper area. Additionally, defects from the forming process should be minimized. In order to simulate the slitting process, whereby sheared corrugated patterns are formed, ductile fracture criteria based on the histories of stress and strain are employed. The user material subroutine VUMAT is employed for implementation of the material and ductile fracture criteria in the commercial FEM software ABAQUS. The variables of the ductile fracture criteria were determined by comparing the simulation results and the experimental results of the tension test and the shearing test. Parametric studies were conducted to determine the critical value of the ductile fracture criterion. Employing these ductile fracture criteria, the three dimensional forming process of the shielded slot plate was numerically simulated. The effects of the slitting process in the forming process of the shielded slot plate were analyzed through a FEM simulation and experimental studies. Finally, experiments involving microscopic and macroscopic observations were conducted to verify the numerical simulations of the 3-step forming process.

  20. Evaluation of volatile behaviour and the volatilization volume of molten salt in DIR-MCFC by using the image measurement technique

    Sugiura, Kimihiko; Yamauchi, Makoto; Tanimoto, Kazumi; Yoshitani, Yasumasa

    The volatilization of molten salt is one of the factors that control the performance of molten carbonate fuel cells (MCFC). Volatilization of molten salt promotes the cross-leakage and corrosion of metallic components. Moreover, pipe blockage is caused by the solidification of volatile matter. Especially, because reforming catalysts filling the anode channel are polluted by molten salt volatile matter in direct internal reforming molten carbonate fuel cells (DIR-MCFC), volatilizing of the molten salt is a weighty subject. However, neither the behaviour nor the volatilization volume of molten salt volatile matter has been elucidated, because molten salt volatile matter that has strong alkalinity cannot be supplied directly to an analyzer, its volatilization volume is small, and the analytical accuracy is poor. Therefore, an attempt was made to elucidate the behaviour of vaporized alkali hydroxide by using a non-contact image measurement technique. The DIR-MCFC electrolyte is generally 62Li 2CO 3/38K 2CO 3. Consideration was given to the DIR-MCFC catalyst pollution mechanism as follows. Molten salt volatile matter is KOH generated as water generated in the cell reacts with the electrolyte. The generated KOH returns to K 2CO 3 again in high CO 2 concentration regions, and catalyst pollution is caused by the adherence of the K 2CO 3 to the catalyst. Moreover, the K 2CO 3 particles mutually cohere when the generated water assists bonding and blocks the piping. The present report experimentally evaluates the volatilization volume of KOH, the change from KOH to K 2CO 3, and the particulate growth of K 2CO 3, using the image measurement technique. In measuring the KOH volatilization volume, K 2CO 3 is generated as KOH volatilized by heating it in a crucible in an electric furnace reacts with CO 2, and is then injected into a reaction tube. The amount of K 2CO 3 is measured by measuring the image of the K 2CO 3 particle with a YAG laser and a CCD camera, thereby obtaining

    LiFeO 2 was coated on porous NiO cathode using a simple combustion process. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed in the cathode characterizations. The electrochemical behaviors of LiFeO 2 coated NiO cathode (LFO-NiO) were also evaluated in a molten 62 mol% Li 2CO 3 + 38 mol% K 2CO 3 eutectic at 650 °C under the standard cathode gas condition by electrochemical impedance spectroscopy (EIS). The impedance response of the NiO and LFO-NiO at different immersion time is characterized by the presence of depressed semicircles in the high frequency range changing over into the lines with the angle of which observed with the real axis differing 45° or 90° in the low frequency range. The experimental Nyquist plots can be well analyzed theoretically with a modified model based on the well known Randles-Ershler equivalent circuit model. In the new model, the double layer capacity ( Cd) is replaced by the parallel combination of Cd and b/ ω to take into consideration the non-uniform of electric field at the electrode/electrolyte interface owing to the roughness of electrode surface. The LFO-NiO showed a lower dissolution and a good catalytic efficiency close to the state-of-the-art NiO value. In the unit cell test, the performance of the cell composed of LiFeO 2 coated NiO cathode maintained more stable values than that of the cell composed of NiO cathode. Thus the cathode prepared with coating method to coat LiFeO 2 on the surface of NiO cathode is able to reduce the solubility of NiO to lengthen the lifetime of MCFC while maintaining the advantages of NiO cathode.

    For many years, the emphasis has been placed on the performance of the aircraft, rather than on those who fly the aircraft. This is largely due to the relative safety of flying. Just in the last few years there have been several major accidents that have shown that flying is not quite as safe as it was thought to be. Sixty-five percent of these accidents are a result of pilot performance decrements, and so it is obvious that there is a need to reduce that figure. A study has been mandated to evaluate the performance of pilots. This includes workload, circadium rhythms, jet lag, and any other factors which might affect a pilot's performance in the cockpit. The purpose of this study is to find out when and why the decrement in a pilot's performance occur and how to remedy the situation.

    The catalytic behavior of the bare and K-promoted 21% Ni/MgO catalyst in the ethanol steam reforming at MCFC operative conditions has been investigated. The effect of K loading (1-3 wt.%) on the catalytic activity, stability and coking rate have been addressed. K addition stabilizes Ni catalyst mainly by depressing the metal sintering, while coke formation does not seem to be influenced by alkali addition. Endurance test (500 h -1) performed at 20,000 h -1 allows foresee a very long catalyst life in the case of practical application. High H 2 productivity (>5 mol H 2/mol fed ethanol) was obtained. A change in the electronic properties of the active phase accounts for the effect of K addition on the catalytic behavior of the Ni/MgO catalyst.

    The aircraft control time history predicted by the optimal control pilot model and actual pilot tracking data obtained from NASA Langley's differential maneuvering simulator (DMS) are analyzed. The analysis is performed using a hypothesis testing scheme modified to allow for changes in the true hypothesis. A finite number of pilot models, each with different hypothesized internal model representations of the aircraft dynamics, are constructed. The hypothesis testing scheme determines the relative probability that each pilot model best matches the DMS data. By observing the changes in probabilities, it is possible to determine when the pilot changes control strategy and which hypothesized pilot model best represent's the pilot's control behavior.

    The Pilot Weather Advisor (PWA) system is an automated satellite radio-broadcasting system that provides nearly real-time weather data to pilots of aircraft in flight anywhere in the continental United States. The system was designed to enhance safety in two distinct ways: First, the automated receipt of information would relieve the pilot of the time-consuming and distracting task of obtaining weather information via voice communication with ground stations. Second, the presentation of the information would be centered around a map format, thereby making the spatial and temporal relationships in the surrounding weather situation much easier to understand

    1978-01-01

    An augmentation synthesis method usable in the absence of quantitative handling qualities specifications, and yet explicitly including design objectives based on pilot-rating concepts, is presented. The algorithm involves the unique approach of simultaneously solving for the stability augmentation system (SAS) gains, pilot equalization and pilot rating prediction via optimal control techniques. Simultaneous solution is required in this case since the pilot model (gains, etc.) depends upon the augmented plant dynamics, and the augmentation is obviously not a priori known. Another special feature is the use of the pilot's objective function (from which the pilot model evolves) to design the SAS.

    NSTAR Electric & Gas Corporation (“the Company”, or “NSTAR”) developed and implemented a Smart Grid pilot program beginning in 2010 to demonstrate the viability of leveraging existing automated meter reading (“AMR”) deployments to provide much of the Smart Grid functionality of advanced metering infrastructure (“AMI”), but without the large capital investment that AMI rollouts typically entail. In particular, a central objective of the Smart Energy Pilot was to enable residential dynamic pricing (time-of-use “TOU” and critical peak rates and rebates) and two-way direct load control (“DLC”) by continually capturing AMR meter data transmissions and communicating through customer-sited broadband connections in conjunction with a standardsbased home area network (“HAN”). The pilot was supported by the U.S. Department of Energy’s (“DOE”) through the Smart Grid Demonstration program. NSTAR was very pleased to not only receive the funding support from DOE, but the guidance and support of the DOE throughout the pilot. NSTAR is also pleased to report to the DOE that it was able to execute and deliver a successful pilot on time and on budget. NSTAR looks for future opportunities to work with the DOE and others in future smart grid projects.

    A multi-well microbially enhanced oil recovery field pilot has been performed in the Southeast Vassar Vertz Sand Unit in Payne County, Oklahoma. The primary emphasis of the experiment was preferential plugging of high permeability zones for the purpose of improving waterflood sweep efficiency. Studies were performed to determine reservoir chemistry, ecology, and indigenous bacteria populations. Growth experiments were used to select a nutrient system compatible with the reservoir that encouraged growth of a group of indigenous nitrate-using bacteria and inhibit growth of sulfate-reducing bacteria. A specific field pilot area behind an active line drive waterflood was selected. Surface facilities were designed and installed. Injection protocols of bulk nutrient materials were prepared to facilitate uniform distribution of nutrients within the pilot area. By the end of December, 1991, 82.5 tons (75.0 tonnes) of nutrients had been injected in the field. A tracer test identified significant heterogeneity in the SEVVSU and made it necessary to monitor additional production wells in the field. The tracer tests and changes in production behavior indicate the additional production wells monitored during the field trial were also affected. Eighty two and one half barrels (13.1 m[sup 3]) of tertiary oil have been recovered. Microbial activity has increased CO[sub 2] content as indicated by increased alkalinity. A temporary rise in sulfide concentration was experienced. These indicate an active microbial community was generated in the field by the nutrient injection. Pilot area interwell pressure interference test results showed that significant permeability reduction occurred. The interwell permeabilities in the pilot area between the injector and the three pilot production wells were made more uniform which indicates a successful preferential plugging enhanced oil recovery project.

  1. Pilots 2.0: DIRAC pilots for all the skies

    NASA Astrophysics Data System (ADS)

    Stagni, F.; Tsaregorodtsev, A.; McNab, A.; Luzzi, C.

    2015-12-01

    In the last few years, new types of computing infrastructures, such as IAAS (Infrastructure as a Service) and IAAC (Infrastructure as a Client), gained popularity. New resources may come as part of pledged resources, while others are opportunistic. Most of these new infrastructures are based on virtualization techniques. Meanwhile, some concepts, such as distributed queues, lost appeal, while still supporting a vast amount of resources. Virtual Organizations are therefore facing heterogeneity of the available resources and the use of an Interware software like DIRAC to hide the diversity of underlying resources has become essential. The DIRAC WMS is based on the concept of pilot jobs that was introduced back in 2004. A pilot is what creates the possibility to run jobs on a worker node. Within DIRAC, we developed a new generation of pilot jobs, that we dubbed Pilots 2.0. Pilots 2.0 are not tied to a specific infrastructure; rather they are generic, fully configurable and extendible pilots. A Pilot 2.0 can be sent, as a script to be run, or it can be fetched from a remote location. A pilot 2.0 can run on every computing resource, e.g.: on CREAM Computing elements, on DIRAC Computing elements, on Virtual Machines as part of the contextualization script, or IAAC resources, provided that these machines are properly configured, hiding all the details of the Worker Nodes (WNs) infrastructure. Pilots 2.0 can be generated server and client side. Pilots 2.0 are the “pilots to fly in all the skies”, aiming at easy use of computing power, in whatever form it is presented. Another aim is the unification and simplification of the monitoring infrastructure for all kinds of computing resources, by using pilots as a network of distributed sensors coordinated by a central resource monitoring system. Pilots 2.0 have been developed using the command pattern. VOs using DIRAC can tune pilots 2.0 as they need, and extend or replace each and every pilot command in an easy way. In this

    Operations under single pilot instrument flight rules for general aviation aircraft is known to be one of the most demanding pilot tasks. Scanning numerous instruments plays a key role for perception and decision-making during flight. Flight experiments have been done by a single engine light airplane to investigate the pilot eye scanning technique for IFR flights. Comparisons between the results by an actual flight and those by a PC-based flight simulator are made. The experimental difficulties of pilot eye scanning measurements during the actual IFR flight are discussed.

    1990-11-01

    This report covers progress made during the first year of the Microbial Field Pilot Study project. Information on reservoir ecology and characterization, facility and treatment design, core experiments, bacterial mobility, and mathematical modeling are addressed. To facilitate an understanding of the ecology of the target reservoir analyses of the fluids which support bacteriological growth and the microbiology of the reservoir were performed. A preliminary design of facilities for the operation of the field pilot test was prepared. In addition, procedures for facilities installation and for injection treatments are described. The Southeast Vassar Vertz Sand Unit (SEVVSU), the site of the proposed field pilot study, is described physically, historically, and geologically. The fields current status is presented and the ongoing reservoir simulation is discussed. Core flood experiments conducted during the last year were used to help define possible mechanisms involved in microbial enhanced oil recovery. Two possible mechanisms, relative permeability effects and changes in the capillary number, are discussed and related to four Berea core experiments' results. The experiments were conducted at reservoir temperature using SEVVSU oil, brine, and bacteria. The movement and activity of bacteria in porous media were investigated by monitoring the growth of bacteria in sandpack cores under no flow conditions. The rate of bacteria advancement through the cores was determined. A mathematical model of the MEOR process has been developed. The model is a three phase, seven species, one dimensional model. Finite difference methods are used for solution. Advection terms in balance equations are represented with a third- order upwind differencing scheme to reduce numerical dispersion and oscillations. The model is applied to a batch fermentation example. 52 refs., 26 figs., 21 tabs.

  9. Microbial field pilot study

    Knapp, R.M.; McInerney, M.J.; Menzie, D.E.; Chisholm, J.L.

    1992-03-01

    The objective of this project is to perform a microbial enhanced oil recovery field pilot in the Southeast Vassar Vertz Sand Unit (SEVVSU) in Payne County, Oklahoma. Indigenous, anaerobic, nitrate reducing bacteria will be stimulated to selectively plug flow paths which have been referentially swept by a prior waterflood. This will force future flood water to invade bypassed regions of the reservoir and increase sweep efficiency. This report covers progress made during the second year, January 1, 1990 to December 31, 1990, of the Microbial Field Pilot Study project. Information on reservoir ecology, surface facilities design, operation of the unit, core experiments, modeling of microbial processes, and reservoir characterization and simulation are presented in the report. To better understand the ecology of the target reservoir, additional analyses of the fluids which support bacteriological growth and the microbiology of the reservoir were performed. The results of the produced and injected water analysis show increasing sulfide concentrations with respect to time. In March of 1990 Mesa Limited Partnership sold their interest in the SEVVSU to Sullivan and Company. In April, Sullivan and Company assumed operation of the field. The facilities for the field operation of the pilot were refined and implementation was begun. Core flood experiments conducted during the last year were used to help define possible mechanisms involved in microbial enhanced oil recovery. The experiments were performed at SEVVSU temperature using fluids and inoculum from the unit. The model described in last year's report was further validated using results from a core flood experiment. The model was able to simulate the results of one of the core flood experiments with good quality.

This Augmentation Pilot Project focused on the areas of community-school alliances and intemet technology use in teaching and learning and daily living addressing five major objectives.

  15. Pilot's Desk Flight Station

    NASA Technical Reports Server (NTRS)

    Sexton, G. A.

    1984-01-01

    Aircraft flight station designs have generally evolved through the incorporation of improved or modernized controls and displays. In connection with a continuing increase in the amount of information displayed, this process has produced a complex and cluttered conglomeration of knobs, switches, and electromechanical displays. The result was often high crew workload, missed signals, and misinterpreted information. Advances in electronic technology have now, however, led to new concepts in flight station design. An American aerospace company in cooperation with NASA has utilized these concepts to develop a candidate conceptual design for a 1995 flight station. The obtained Pilot's Desk Flight Station is a unique design which resembles more an operator's console than today's cockpit. Attention is given to configuration, primary flight controllers, front panel displays, flight/navigation display, approach charts and weather display, head-up display, and voice command and response systems.

    Autopilot replaces pilot during automatic maneuvers. Pilot, based on ground, flies aircraft to required altitude, then turns control over to autopilot. Increases quality of maneuvers significantly beyond that attainable through remote manual control by pilot on ground. Also increases quality of maneuvers because it performs maneuvers faster than pilot could and because it does not have to repeat poorly executed maneuvers.

  15. Stress and workload in pilots.

    PubMed

    Roscoe, A H

    1978-04-01

    Several studies have highlighted the increase in physiological activity which occurs in pilots during flight and especially during takeoffs and landings. For example, it has been clearly demonstrated that pilots' heart rates increase during the landing approach to reach a peak at or just before touchdown. These changes have been attributed to workload and to psychological or emotional stress. This paper examines a number of test pilots' heart rate responses recorded during various flight trials involving different types of aircraft. Examples include ramp takeoffs in a VTOL fighter, automatic landings in fog, supersonic flight through monsoon rain, and a sortie in which the pilot developed acute appendicitis. It is concluded that heart rate responses in experienced pilots are influenced almost entirely by workload-related factors and not by emotional stressors, such as risk and anxiety. Because of the emotional overtones of the word "stress," it is suggested that the term workload should be used when referring to the reason for increased cardiovascular activity of pilots.

  16. Active Job Monitoring in Pilots

    NASA Astrophysics Data System (ADS)

    Kuehn, Eileen; Fischer, Max; Giffels, Manuel; Jung, Christopher; Petzold, Andreas

    2015-12-01

    Recent developments in high energy physics (HEP) including multi-core jobs and multi-core pilots require data centres to gain a deep understanding of the system to monitor, design, and upgrade computing clusters. Networking is a critical component. Especially the increased usage of data federations, for example in diskless computing centres or as a fallback solution, relies on WAN connectivity and availability. The specific demands of different experiments and communities, but also the need for identification of misbehaving batch jobs, requires an active monitoring. Existing monitoring tools are not capable of measuring fine-grained information at batch job level. This complicates network-aware scheduling and optimisations. In addition, pilots add another layer of abstraction. They behave like batch systems themselves by managing and executing payloads of jobs internally. The number of real jobs being executed is unknown, as the original batch system has no access to internal information about the scheduling process inside the pilots. Therefore, the comparability of jobs and pilots for predicting run-time behaviour or network performance cannot be ensured. Hence, identifying the actual payload is important. At the GridKa Tier 1 centre a specific tool is in use that allows the monitoring of network traffic information at batch job level. This contribution presents the current monitoring approach and discusses recent efforts and importance to identify pilots and their substructures inside the batch system. It will also show how to determine monitoring data of specific jobs from identified pilots. Finally, the approach is evaluated.

    1994-12-31

    Manufacturing Sciences Corporation (MSC) has undertaken a project from the U.S. Department of Energy (DOE) to convert buildings that are currently contaminated at Rocky Flats into buildings that are capable of producing commercial products. This conversion project is called the National Conversion Pilot Project (NCPP). The mission of the NCPP is to explore and demonstrate at the Rocky Flats site the feasibility of economic conversion at DOE facilities. This project was officially started on April 1 with the signing of a Cooperative Assistance Agreement between MSC and the DOE. The NCPP was jointly announced by Roy Romer, Governor of the State of Colorado; Mark Silverman, Manager of the Department of Energy Rocky Flats Office; Jack McGraw, Activity Administrator for U.S. Environmental Protection Agency (EPA) Region 8; and Tom Looby, Director of the Office of Environment from the Colorado Department of Health. On March 25, 1994, Hazel O`Leary, the Secretary of the DOE, toured the site of the NCPP and heartily endorsed the project as an example of how the DOE and commercial industry can jointly accomplish the conversion and cleanup of government facilities into productive commercial ventures.

  1. Mortality among British Columbia pilots.

    PubMed

    Salisbury, D A; Band, P R; Threlfall, W J; Gallagher, R P

    1991-04-01

    We studied the mortality experience of all pilots who died in the province of British Columbia between 1950 and 1984, using proportional mortality ratios (PMR) and proportional cancer mortality ratios (PCMR). There were 341 deaths during that time in males whose usual occupation was listed as pilot. The PMR for aircraft accidents was significantly elevated (PMR = 3196, 95% C.I. 2810, 3634), and the PMR for atherosclerotic heart disease was significantly depressed (PMR = 47, 95% C.I. 30, 70). Although based on small numbers of deaths, and not statistically significant, elevated PCMRs were seen for cancers of the colon, brain, and nervous system, as well as for Hodgkin's disease. These findings suggest the need for further epidemiologic studies of commercial airline pilots. PMID:2031640

    1984-10-01

    The concept of an environmental specimen bank for archiving of biological and environmental samples for retrospective analysis has been recognized recently as an important component of systematic environmental monitoring. A pilot program was designed to evaluate the feasibility of a national program by providing actual working experience in all aspects of specimen banking, that is, in specimen collection, processing, storage, and analysis. Four types of environmental specimens, which represent environmental accumulators, were selected for inclusion in the National Bureau of Standards pilot program: human soft tissue (liver), a marine accumulator (marine mussels, Mytilus edulis), a food accumulator and the air pollutant accumulator have not been selected. Attention is focused on the experience gained in the pilot program with the human liver specimens. 32 references, 2 figures, 1 table.

    1983-01-01

    Methods for nonintrusive identification of pilot control strategy and task execution dynamics are presented along with examples based on flight data. The specific analysis technique is Nonintrusive Parameter Identification Procedure (NIPIP), which is described in a companion user's guide (NASA CR-170398). Quantification of pilot control strategy and task execution dynamics is discussed in general terms followed by a more detailed description of how NIPIP can be applied. The examples are based on flight data obtained from the NASA F-8 digital fly by wire airplane. These examples involve various piloting tasks and control axes as well as a demonstration of how the dynamics of the aircraft itself are identified using NIPIP. Application of NIPIP to the AFTI/F-16 flight test program is discussed. Recommendations are made for flight test applications in general and refinement of NIPIP to include interactive computer graphics.

  14. Piloting By Heart And By Chart

    NASA Astrophysics Data System (ADS)

    Lützhöft, Margareta H.; Nyce, James M.

    2006-05-01

    This paper describes the complexity of the Baltic archipelago, and the navigational and operational processes involved in piloting these waters. This four year ethnographic study shows how piloting is learned, performed, and passed on to the next generation of pilots. The blend of new technology and old methods is discussed, the indivisibility of working and learning, and the individuality of the mental constructs of the mariners/pilots.

    Commercial pilot eye scanning data previously collected were reanalyzed to evaluate how pilots used the drum pointer altimeter. The results of these tests showed that the pilots seldom used the drum window apparently because it was difficult to read as indicated by average drum window dwell times of 0.6 sec. It is suggested that pilot scanning data be collected for other types of altimeters in order to find those with good scanning characteristics.

  17. An analytical prediction of pilot ratings utilizing human pilot model

    NASA Technical Reports Server (NTRS)

    Tanaka, K.; Washizu, K.

    1982-01-01

    In order to analytically predict pilot ratings, an evaluation method of a manual control system which consists of an aircraft and a human pilot, is proposed and examined. The method is constructed upon the assumptions that the control mission determines the critical frequency the pilot should bring to his focus, and that the degree of closed-loop stability and the human compensation necessary to attain the stability determine the human subjective evaluation of the system. As a result, a simple evaluation chart is introduced. The chart enables prediction of the subjective evaluation, if the controlled element dynamics and the mission are given. The chart is in good accord with almost all of the existing results of pilot ratings. This method has the following advantages: (1) simplicity, in a sense that the method needs to evaluate only two typical controlled element parameters, namely, the gain slope and the phase at the critical control frequency; (2) applicability to unstable controlled elements; (3) predictability of controllability limits of manual control; (4) possibility of estimating human compensatory dynamics.

  1. HL-10 pilots assist with pilot entry into lifting body

    NASA Technical Reports Server (NTRS)

    1969-01-01

    Not every moment of a test pilot's day is serious business. In a moment of levity, NASA pilots Bill Dana (left) and John A. Manke try to drag Air Force test pilot Peter Hoag away from the HL-10 lifting body while Air Force Major Jerauld R. Gentry helps from the cockpit. These four men were the principal pilots for the HL-10 program. This was not the only prank involving the HL-10 and its pilots. Once 'Captain Midnight' (Gentry) and the 'Midnight skulkers' sneaked into the NASA hangar and put 'U.S. Air Force' on the aircraft using stick-on letters. Later, while Gentry was making a lifting-body flight, his 1954 Ford was 'borrowed' from the parking lot, painted with yellow-green zinc-chromate primer, and decorated with large stick-on flowers about one foot in diameter. After Gentry returned from the flight, he was surprised to see what had happened to his car. The HL-10 was one of five heavyweight lifting-body designs flown at NASA's Flight Research Center (FRC--later Dryden Flight Research Center), Edwards, California, from July 1966 to November 1975 to study and validate the concept of safely maneuvering and landing a low lift-over-drag vehicle designed for reentry from space. Northrop Corporation built the HL-10 and M2-F2, the first two of the fleet of 'heavy' lifting bodies flown by the NASA Flight Research Center. The contract for construction of the HL-10 and the M2-F2 was $1.8 million. 'HL' stands for horizontal landing, and '10' refers to the tenth design studied by engineers at NASA's Langley Research Center, Hampton, Va. After delivery to NASA in January 1966, the HL-10 made its first flight on Dec. 22, 1966, with research pilot Bruce Peterson in the cockpit. Although an XLR-11 rocket engine was installed in the vehicle, the first 11 drop flights from the B-52 launch aircraft were powerless glide flights to assess handling qualities, stability, and control. In the end, the HL-10 was judged to be the best handling of the three original heavy-weight lifting

  2. Pilot mental workload: how well do pilots really perform?

    PubMed

    Morris, Charles H; Leung, Ying K

    2006-12-15

    The purpose of this study was to investigate the effects of increasing mental demands on various aspects of aircrew performance. In particular, the robustness of the prioritization and allocation hierarchy of aviate-navigate-communicate was examined, a hierarchy commonly used within the aviation industry. A total of 42 trainee pilots were divided into three workload groups (low, medium, high) to complete a desktop, computer-based exercise that simulated combinations of generic flight deck activities: flight control manipulation, rule-based actions and higher level cognitive processing, in addition to Air Traffic Control instructions that varied in length from one chunk of auditory information to seven chunks. It was found that as mental workload and auditory input increased, participants experienced considerable difficulty in carrying out the primary manipulation task. A similar decline in prioritization was also observed. Moreover, when pilots were under a high mental workload their ability to comprehend more than two chunks of auditory data deteriorated rapidly.

    Demmer, Rick L.; Fox, Don T.; Archiblad, Kip E.

    2015-01-01

    Experiments in 2006 developed a useful fog solution using three different chemical constituents. Optimization of the fog recipe and use of commercially available equipment were identified as needs that had not been addressed. During 2012 development work it was noted that low concentrations of the components hampered coverage and drying in the United Kingdom’s National Nuclear Laboratory’s testing much more so than was evident in the 2006 tests. In fiscal year 2014 the Idaho National Laboratory undertook a systematic optimization of the fogging formulation and conducted a non-radioactive, pilot scale demonstration using commercially available fogging equipment. While not as sophisticated as the equipment used in earlier testing, the new approach is much less expensive and readily available for smaller scale operations. Pilot scale testing was important to validate new equipment of an appropriate scale, optimize the chemistry of the fogging solution, and to realize the conceptual approach.

  4. Piloted simulator assessments of agility

    NASA Technical Reports Server (NTRS)

    Schneider, Edward T.

    1990-01-01

    NASA has utilized piloted simulators for nearly two decades to study high-angle-of-attack flying qualities, agility, and air-to-air combat. These studies have included assessments of an F-16XL aircraft equipped with thrust vectoring, an assessment of the F-18 HARV maneuvering requirements to assist in thrust vectoring control system design, and an agility assessment of the F-18. The F-18 agility assessment was compared with in-flight testing. Open-loop maneuvers such as 180-deg rolls to measure roll rate showed favorable simulator/in-flight comparison. Closed-loop maneuvers such as rolls to 90 deg with precision stops or certain maximum longitudinal pitching maneuvers showed poorer performance due to reduced aggressiveness of pilot inputs in flight to remain within flight envelope limits.

  5. Pilot Fatigue and Circadian Desynchronosis

    NASA Technical Reports Server (NTRS)

    1981-01-01

    Pilot fatigue and circadian desynchronosis, its significance to air transport safety, and research approaches, were examined. There is a need for better data on sleep, activity, and other pertinent factors from pilots flying a variety of demanding schedules. Simulation studies of flight crew performance should be utilized to determine the degree of fatigue induced by demanding schedules and to delineate more precisely the factors responsible for performance decrements in flight and to test solutions proposed to resolve problems induced by fatigue and desynchronosis. It was concluded that there is a safety problem of uncertain magnitude due to transmeridian flying and a potential problem due to fatigue associated with various factors found in air transport operations.

    2015-03-01

    Planning a well-designed research study can be tedious and laborious work. However, this process is critical and ultimately can produce valid, reliable study findings. Designing a large-scale randomized, controlled trial (RCT)-the gold standard in quantitative research-can be even more challenging. Even the most well-planned study potentially can result in issues with research procedures and design, such as recruitment, retention, or methodology. One strategy that may facilitate sound study design is the completion of a pilot or feasibility study prior to the initiation of a larger-scale trial. This article will discuss pilot and feasibility studies, their advantages and disadvantages, and implications for oncology nursing research.

    The National Conversion Pilot Project (NCPP) is a recycling project under way at the U.S. Department of Energy (DOE) Rocky Flats Environmental Technology Site (RFETS) in Colorado. The recycling aim of the project is threefold: to reuse existing nuclear weapon component production facilities for the production of commercially marketable products, to reuse existing material (uranium, beryllium, and radioactively contaminated scrap metals) for the production of these products, and to reemploy former Rocky Flats workers in this process.

  8. Carbon dioxide cleaning pilot project

    SciTech Connect

    Knight, L.; Blackman, T.E.

    1994-01-21

    In 1989, radioactive-contaminated metal at the Rocky Flats Plant (RFP) was cleaned using a solvent paint stripper (Methylene chloride). One-third of the radioactive material was able to be recycled; two-thirds went to the scrap pile as low-level mixed waste. In addition, waste solvent solutions also required disposal. Not only was this an inefficient process, it was later prohibited by the Resource Conservation and Recovery Act (RCRA), 40 CFR 268. A better way of doing business was needed. In the search for a solution to this situation, it was decided to study the advantages of using a new technology - pelletized carbon dioxide cleaning. A proof of principle demonstration occurred in December 1990 to test whether such a system could clean radioactive-contaminated metal. The proof of principle demonstration was expanded in June 1992 with a pilot project. The purpose of the pilot project was three fold: (1) to clean metal so that it can satisfy free release criteria for residual radioactive contamination at the Rocky Flats Plant (RFP); (2) to compare two different carbon dioxide cleaning systems; and (3) to determine the cost-effectiveness of decontamination process in a production situation and compare the cost of shipping the metal off site for waste disposal. The pilot project was completed in August 1993. The results of the pilot project were: (1) 90% of those items which were decontaminated, successfully met the free release criteria , (2) the Alpheus Model 250 was selected to be used on plantsite and (3) the break even cost of decontaminating the metal vs shipping the contaminated material offsite for disposal was a cleaning rate of 90 pounds per hour, which was easily achieved.

  9. Improvement of electricity generating performance and life expectancy of MCFC stack by applying Li/Na carbonate electrolyte. Test results and analysis of 0.44 m 2/10 kW- and 1.03 m 2/10 kW-class stack

    Yoshiba, Fumihiko; Morita, Hiroshi; Yoshikawa, Masahiro; Mugikura, Yoshihiro; Izaki, Yoshiyuki; Watanabe, Takao; Komoda, Mineo; Masuda, Yuji; Zaima, Nobuyuki

    Following the development of a 10 kW-class MCFC stack with a reactive area of 0.44 and 1.03 m 2, which applies a Li/Na carbonate electrolyte and a press stamping separator, many tests have now been carried out. In the installation tests, the observed cell voltages of the 0.44 m 2/10 kW-class stack agreed with the voltage predicted from the test results of the 100 cm 2 bench scale cell. This agreement proves that the installing procedure of the bench scale cell can be applied to the 0.44 m 2/10 kW-class stacks. The temperature distribution analysis model applied to the 100 kW-class stack was modified to calculate the temperature distribution of the 0.44 m 2/10 kW-class stack. Taking the heat loss and the heat transfer effect of the stack holder into account, the calculated temperature was close to the measured temperature; this result proves that the modification was adequate for the temperature analysis model. In the high current density operating tests on the 0.44 m 2/10 kW-class stack, an electrical power density of 2.46 kW/m 2 was recorded at an operating current density of 3000 A/m 2. In the endurance test on the 0.44 m 2/10 kW-class stack, however, unexpected Ni shortening occurred during the operating period 2500-4500 h, which had been caused by a defective formation of the electrolyte matrix. The shortening seems to have been caused by the crack, which appeared in the electrolyte matrix. The voltage degradation rate of the 0.44 m 2/10 kW-class stack was 0.52% over 1000 h, which proves that the matrix was inadequate for a long life expectancy of the MCFC stack. A final endurance test was carried out on the 1.03 m 2/10 kW-class stack, of which the matrix had been revised. The fuel utilisation and the leakage of anode gas never changed during the 10,000 h operating test. This result suggests that no shortening occurred during the 10,000 h endurance test. The cell voltage degradation rate was around 0.2-0.3% over 1000 h in the 1.03 m 2/10 kW-class stack

  20. Global positioning system supported pilot's display

    NASA Technical Reports Server (NTRS)

    Scott, Marshall M., Jr.; Erdogan, Temel; Schwalb, Andrew P.; Curley, Charles H.

    1991-01-01

    The hardware, software, and operation of the Microwave Scanning Beam Landing System (MSBLS) Flight Inspection System Pilot's Display is discussed. The Pilot's Display is used in conjunction with flight inspection tests that certify the Microwave Scanning Beam Landing System used at Space Shuttle landing facilities throughout the world. The Pilot's Display was developed for the pilot of test aircraft to set up and fly a given test flight path determined by the flight inspection test engineers. This display also aids the aircraft pilot when hazy or cloud cover conditions exist that limit the pilot's visibility of the Shuttle runway during the flight inspection. The aircraft position is calculated using the Global Positioning System and displayed in the cockpit on a graphical display.

  1. Predicting pilot-error incidents of US airline pilots using logistic regression.

    PubMed

    McFadden, K L

    1997-06-01

    In a population of 70,164 airline pilots obtained from the Federal Aviation Administration, 475 males and 22 females had pilot-error incidents in the years 1986-1992. A simple chi-squared test revealed that female pilots employed by major airlines had a significantly greater likelihood of pilot-error incidents than their male colleagues. In order to control for age, experience (total flying hours), risk exposure (recent flying hours) and employer (major/non-major airline) simultaneously, the author built a model of male pilot-error incidents using logistic regression. The regression analysis indicated that youth, inexperience and non-major airline employer were independent contributors to the increased risk of pilot-error incidents. The results also provide further support to the literature that pilot performance does not differ significantly between male and female airline pilots. PMID:9414359

    SciTech Connect

    Willax, H.O.; Lahr, H.

    1995-12-31

    In the Federal Republic of Germany, the feasibility of direct disposal of spent fuel elements has been examined and their safety aspects evaluated in the years between 1979 and 1985. In an assessment of the results, the Federal Government concluded that the technology of direct disposal has to be developed. According to this decision in April 1986, there was the application for the erection and operation of the Pilot Conditioning Plant (PKA) for the conditioning of spent fuel elements and other radioactive waste. Since February 1990, the PKA has been under construction and the hot commissioning will be in 1997.

    2006-10-01

    The Advanced Engineering Environment (AEE) is a concurrent engineering concept that enables real-time process tooling design and analysis, collaborative process flow development, automated document creation, and full process traceability throughout a product's life cycle. The AEE will enable NNSA's Design and Production Agencies to collaborate through a singular integrated process. Sandia National Laboratories and Parametric Technology Corporation (PTC) are working together on a prototype AEE pilot project to evaluate PTC's product collaboration tools relative to the needs of the NWC. The primary deliverable for the project is a set of validated criteria for defining a complete commercial off-the-shelf (COTS) solution to deploy the AEE across the NWC.

  14. Objective measure of pilot workload

    Kantowitz, B. H.

    1984-01-01

    Timesharing behavior in a data-entry task, similar to a pilot entering navigation data into an on-board computer is investigated. Auditory reaction time as a function of stimulus information and dimensionality is examined. This study has direct implications for stimulus selection for secondary tasks used in the GAT flight simulator at Ames Research Center. Attenuation effects of heat and cold stress in a psychological refractory period task were studied. The focus of interest is the general effects of stress on attention rather than upon specific temperature related phenomena.

    Pilot plant makes oxygen difluoride highly-energetic, space-storable oxidizer not made commercially. Designed to handle reactants, product, and byproduct, most of which highly reactive, corrosive, and toxic. Oxygen difluoride evolves continuously from reactor containing potassium hydroxide in water at 10 degree C. Collection tanks alternated; one filled while other drained to storage cylinder. Excess OF2 and F2 dissipated in combustion of charcoal in burn barrel. Toxic byproduct, potassium fluoride, reacted with calcium hydroxide to form nontoxic calcium fluoride and to regenerate potassium hydroxide. Equipment processes toxic, difficult-to-make substance efficiently and safely.

  16. A method for generating numerical pilot opinion ratings using the optimal pilot model

    NASA Technical Reports Server (NTRS)

    Hess, R. A.

    1976-01-01

    A method for generating numerical pilot opinion ratings using the optimal pilot model is introduced. The method is contained in a rating hypothesis which states that the numerical rating which a human pilot assigns to a specific vehicle and task can be directly related to the numerical value of the index of performance resulting from the optimal pilot modeling procedure as applied to that vehicle and task. The hypothesis is tested using the data from four piloted simulations. The results indicate that the hypothesis is reasonable, but that the predictive capability of the method is a strong function of the accuracy of the pilot model itself. This accuracy is, in turn, dependent upon the parameters which define the optimal modeling problem. A procedure for specifying the parameters for the optimal pilot model in the absence of experimental data is suggested.
