Abstract
The invention relates to polycomponent electrocatalysts suitable for use at the cathode of electrochemical and fuel cells. More particularly, the invention relates to a polycomponent electrode comprising a catalytic electrode including a mixture of a metallic component including at least one metal selected from palladium, platinum, ruthenium, rhodium, iridium or osmium and a chemical component including at least one compound selected from the group consisting of suitable oxometallates and metallic acids. Preferably, the metallic component comprises at least one metal selected from the group consisting of platinum and palladium and the chemical component comprises at least one compound selected from the group consisting of tungstic acid, molybdic acid, ammonium tungstate, ammonium molybdate, sodium tungstate and sodium molybdate. The electrode is operable in fuel cells which employ readily available oxygen or air.
