    Abstract: An acid resistant composite catalyst comprising dumbbell-shaped composite nanoparticles each comprising a noble metal nanoparticle epitaxially conjugated to a ferrite particle, and/or flower-shaped composite nanoparticles each comprising a noble metal nanoparticle epitaxially conjugated to at least two ferrite particles. The acid resistant composite catalyst is useful to facilitate the reduction of oxygen. The acid resistant composite catalyst can be used in a fuel cell comprising a fuel electrode, an oxygen electrode, and a polymer electrolyte membrane placed between the fuel electrode and the oxygen electrode. The oxygen electrode includes the acid resistant composite catalyst.
