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.

Metal alloy catalysts for fuel cell anodes

A mixed metal oxide material of tungsten and titanium is provided for use in a fuel cell. The material may comprise less than approximately 30 at. % tungsten. The mixed metal oxide may form the core of a core-shell composite material, used as a catalyst support, in which a catalyst such as platinum forms the shell. The catalyst may be applied as a single monolayer, or up to 20 monolayers.

Composite materials

A mixed metal oxide material of tantalumand titanium is provided for use in a fuel cell. The material may comprise between 1 and 20 at. % tantalum. The mixed metal oxide may form the core of a core-shell composite material, used as a catalyst support, in which a catalyst such as platinum forms the shell. The catalyst may be applied as a single monolayer, and is preferably between 6.5 and 9.3 monolayers thick.

A mixed metal oxide material of tin and titanium is provided for use in a fuel cell. The mixed metal oxide may form the core of a core-shell composite material, used as a catalyst support, in which a catalyst such as platinum forms the shell. The catalyst may be applied as a single monolayer, or up to 20 monolayers.
