A method and catalysts for producing a hydrogen-rich syngas are disclosed. According to the method a CO-containing gas contacts a water gas shift (WGS) catalyst, in the presence of water, preferably at a temperature of less than about 450° C. to produce a hydrogen-rich syngas. Also disclosed is a water gas shift catalyst formulated from: a) Pt, its oxides or mixtures thereof, b) at least one of Fe and Rh, their oxides and mixtures thereof, and c) at least one member selected from the group consisting of Sc, Y, Ti, Zr, V, Nb, Ta, Mo, Re, Co, Ni, Pd, Ge, Sn, Sb, La, Ce, Pr, Nd, Sm, and Eu, their oxides and mixtures thereof. The WGS catalyst may be supported on a carrier, such as any one member or a combination of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, yttria and iron oxide. Fuel processors containing such water gas shift catalysts are also disclosed.
