Abstract: The advantages and major problems of platinum-based materials as cathode catalyst for polymer electrolyte membrane fuel cells (PEMFCs) are briefly introduced. The mechanisms of oxygen reduction reaction in acidic and alkaline electrolytes are analyzed and the influences of the adsorption modes of oxygen molecules on the surface of catalyst for the mechanism of oxygen reduction reaction are discussed. The crystalline structures and characteristics of CoSe2 compound and the relationship with catalytic properties are discussed. The CoSe2 compound mainly consists of cubic pyrite type (c-CoSe2) and orthogonal white pyrite type (o-CoSe2). Generally, c-CoSe2 has higher catalytic activity than o-CoSe2. The research progress of the CoSe2/C catalysts is reviewed. In particular, the effects of preparation method, surface modification, transition metal doping, Co/Se ratio and carbon support on the catalytic activity, reaction mechanism, stability and toxicity resistance of CoSe2/C catalysts are reviewed. The existing problems and the development prospects of the CoSe2/C catalyst are pointed out.

Key words: polymer electrolyte membrane fuel cells, non-noble metal catalysts, CoSe2 compound, oxygen reduction reaction, catalytic activity
