Metal Alloy Catalysts for Fuel Cell Anodes

A catalyst for a fuel cell anode comprises an alloy of Pd and at least two other transition metals, at least one of which which binds to hydrogen and/or carbon monoxide at least as strongly as Pd does. Suitable transition metals which bind more strongly are Co, W, Ti, V, Cr, Fe, Mo, Nb, Hf, Ta, Zr a...

description	A catalyst for a fuel cell anode comprises an alloy of Pd and at least two other transition metals, at least one of which which binds to hydrogen and/or carbon monoxide at least as strongly as Pd does. Suitable transition metals which bind more strongly are Co, W, Ti, V, Cr, Fe, Mo, Nb, Hf, Ta, Zr and Re. PdCoW is the most preferred alloy. The catalyst is used on the anode of a hydrogen oxidising fuel cell, such as a PEMFC to catalyse the hydrogen oxidation reaction.
