A method of producing a catalyst suitable for use in a membrane electrode assembly involves providing a mixture comprising a polyaniline precursor and a catalyst support; adding to said mixture an oxidant and a compound comprising a transition metal; agitating said mixture sufficiently to result in polyaniline polymerization; drying the mixture; heating the dried mixture in an inert atmosphere at a temperature of from about 400.degree. C. to about 1000.degree. C.; leaching the mixture with an acid solution; heating the resulting mixture in an inert atmosphere at a temperature of from about 400.degree. C. to about 1000.degree. C. The second heating improves the performance of the catalyst.
