A fuel cell comprising an anode, a cathode, an electrolyte, means for supplying a hydrogen-containing fuel and means for supplying an oxidant. The anode and optionally the cathode includes a catalyst comprising an alloy of the formula: PdxBiyMz, where M is one or more metals, x is 0.1-0.7, y is 0.3-0.9, z is not greater than 0.1 and x + y + z = 1. M is preferably selected from one or more of Re, Ru, Os, Rh, Ir, Ni, Pt, Ag and/or Au. Also a catalyst supported on a bismuth and palladium free support, the catalyst has the formula PdxBiyMz, where M is one or more metals, x is 0.2-0.45, y is 0.55-0.8, z is not greater than 0.1 and x + y + z = 1 and is preferably being suitable for a fuel cell. The support is preferably carbon or a metal oxide. |
