ABSTRACT:
An improved ternary alloy catalyst for fuel cells containing platinum and gallium. The method of fabricating the catalyst in a high surface area supportive form is also described. The resultant fuel cell catalyst displays a substantial resistance to sintering during operation combined with a resistance to a chemical dissolution during operation. These enhancements permit improved long-term operation of fuel cells.
