A novel non-precious metal cathode catalyst,MnCo2O4C/N-C,for use in the oxygen reduction reaction (ORR) in alkaline polymer electrolyte membrane fuel cells,has been synthesized via the pyrolysis of polyaniline. A series of MnCo2O4C/N-C catalysts were prepared at different temperatures. These catalysts were characterized by XRD,Raman spectroscopy,XPS and LSV. The results indicate that the catalyst with 15% MnCo2O4C loading prepared at 900℃ has a higher electrocatalytic activity than others and the ORR onset potential of the catalyst is 0.90V. This catalyst contains more graphitic carbon and nitrogen than the others,which is an important factor in giving the material a higher electrocatalytic activity.
