Development of gold alloy catalyst cathode for alkaline electrolyte fuel cellsA program for the development of improved catalyst and Teflon-bonded electrode structures using this improved catalyst is described, for use in fuel cell cathodes. It was found that Au-Pt was superior to the traditional platinum black as a catalyst. The impetus to the program was provided by the discovery that a life-limiting mechanism on the old catalyst was the gradual dissolution of platinum from the cathode and subsequent redeposition in the electrolyte-containing matrix.
