The resent progress of the catalysts for the fuel processing of the residential fuel cell systems was reviewed. For the preferential oxidation of CO (PROX) reaction, Pt-Fe/Mordenite catalyst exhibited remarkable activity and selectivity. Catalytic activities of the Ni-Fe/CeO2-ZrO2 catalyst prepared by a hard template technique for the water-gas shift reaction were superior to those of a commercial Fe-Cr-based catalyst. The residual chlorine adsorbed on supported Ni catalysts suppressed CO2 dissociation and improved selective CO methanation. The catalytic activity and selectivity of a Ni/Al2O3 catalyst for selective CO methanation were significantly improved by vanadium addition. The maximum CO removal ability and catalyst durability of the Ni/AlVOx catalyst were dramatically improved by the MS coating.
