Abstract

The invention relates to an ORR catalyst material, a preparation method of the ORR catalyst material, an application of the ORR catalyst material as a cathode material of a hydrogen-oxygen fuel cell or a metal-air cell, and the hydrogen-oxygen fuel cell or the metal-air cell. The ORR catalyst material is characterized by meeting the following general formula: Mx / N-C(1-x-y) / (CeO2)y (I), wherein thenoble metal M is one or more than two of Pt, Pd and Au, x and y are mass percentages, the range of x is 5%-6%, and the range of y is 4%-12%. The preparation method of the ORR catalyst material is characterized in that the catalyst precursor material is a noble metal acid radical doped conductive polymer composite material. The invention mainly solves the technical problems of non-uniform noble metal dispersion, poor catalytic performance, complex preparation method of the catalyst material, no environmental protection and high cost of the ORR catalyst material in the prior art.
