ABSTRACT:
Disclosed is a platinum alloy catalyst comprising a carbon support and, platinum, manganese and iron supported thereon. The activities of this platinum alloy catalyst are higher than those of a binary alloy catalyst consisting of platinum and manganese and even of a platinum-nickel-cobalt alloy catalyst which is one of the most active conventional platinum alloy catalysts, and its life is greatly extended. Moreover, it is quite useful when utilized as an electrocatalyst of a fuel cell.
