ABSTRACT:
A platinum alloy catalyst can be used as a fuel cell catalyst. The platinum alloy is a PtAuX alloy wherein X is one or more metals chosen from the group consisting of transition metals, and wherein the alloy contains 40-97% Pt, 1-40% Au and 2-20% X. Electrodes, catalysed membranes and membrane electrode assemblies comprising the catalyst are also disclosed.
