Palladium (Pd) catalysts containing nanosized metal oxides, tungsten oxide (WO3) and tin oxide (SnO2), supported on carbon black (Pd-MOx/C) were synthesized, and the effect of the metal oxide on the oxygen reduction reaction (ORR) in a direct methanol fuel cell (DMFC) was investigated. The SEM images showed that the Pd nanoparticles were highly dispersed on the carbon black, and the metal oxide particles were also distributed well. Pd/C and Pd-WO3/C catalysts as cathode materials for the ORR in DMFCs showed activity similar to or better than that of Pt/C, whereas Pd-SnO2/C showed no improvement in catalytic activity.
