Abstract

The invention is directed towards a CO-tolerant fuel cell electrode formed from a carbon supported, platinum dispersed, non-stoichiometric hydrogen tungsten bronze electrode catalyst. The electrode catalyst is capable of oxidizing CO at very low potentials, and is sequentially formed from stable precursors.
