The objectives of this work were to develop methods for accelerated testing of cathode material for solid oxide fuel cells under selected operating conditions. The methods would be used to evaluate the performance of LSM cathode material.

Batteries for solar photovoltaic applications and other terrestrial applications require long life in daily cycling regimes. There is a need to develop testing procedures to accelerate aging of electrochemical cells so that cycle life data can be acquired in less time than real time testing would require. The ...

In the present paper an electrochemical method for accelerated testing of chloride diffusivity in concrete is presented. The method is based on a theoretical relationship between chloride diffusivity and observed steady-state rate of chloride migration through the concrete. The concentration of the chloride source solution has a ...

The influence of climatic and polluting factors on the atmospheric corrosion of four steels has been examined in the laboratory by an original accelerated electrochemical testing method. This research has led notably to the following conclusions: the corr...

Previous work in our laboratory and elsewhere has suggested that microbially influenced corrosion (MIC) of stainless steels and nickel-base alloys occurs in locally anaerobic regions that support the growth of sulfate-reducing bacteria (SRB). The cathodic...

This research work is intended to compare the anti-corrosive properties of three generations of inorganic phosphate pigments in solvent-based paints and in water-borne ones, both of the epoxy type. The anti-corrosive properties of phosphate pigments were assessed by means of electrochemical techniques (corrosion potential measurements, polarisation tests, ...

An electrochemically monitored etching method has been developed to enable accelerated service life testing of aluminum/zinc alloy coatings with a dendritic microstructure. The method involved pre-exposure of materials to the etching solution to remove the most active phases from the coatings. This process simulated the early phases of ...

Purpose of the research is to improve the properties of current state- of-the-art materials used for SOFCs. The project includes interconnect development, high-performance cathode, electrochemical testing, and accelerated testing. This document reports results of mechanical tests (bend ...

The electrochemical noise (ECN) method was used to evaluate the protectiveness of five alkyl primers containing various inhibitive pigments applied to steel panels. A novel experiment was used to monitor specimens immersed in dilute Harrison`s solution and 2 M sodium chloride. Blistering occurred in the sodium chloride environment and was related to changes in the ECN ...

The electrochemical behavior for Pt catalysts supported on multiwalled carbon nanotubes and Vulcan XC-72 in proton exchange membrane fuel cells under accelerated stress test was examined by cyclic voltammetry, electrochemical impedance spectroscopy, and polarization technique. Pt catalyst supported on multiwalled ...

This paper reviews a testing program conducted at NREL for the past two years that applied voltage, water vapor, and light stresses to thin-film photovoltaic (PV) modules with SnO2:F transparent conducting oxides (TCOs) deposited on soda-lime glass superstrates. Electrochemical corrosion at the glass-TCO interface was observed to result in delamination of ...
