Abstract
Ternary alloy electrocatalysts comprising platinum and at least two less noble elements are described. The ternary alloy electrocatalysts when employed in the cathode of a fuel cell utilizing a phosphoric acid electrolyte provide improved oxygen activity and stability in comparison to unalloyed platinum. The cost of the electrocatalysts is also reduced in comparison to an unalloyed platinum electrocatalyst.
