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.
Claims5
Method of enhancing the electrochemical conversions of fuel and oxygen to water and electricity in a fuel cell, which includes at least one cathode and at least one anode which comprises:
- contacting the reactants with a catalyst, at said at least one cathode, consisting essentially of at least 50 atomic % platinum, gallium and at least one material selected from the group consisting of chromium, cobalt, nickel and mixtures thereof.
