NOVELTY - Preparation of molybdenum nickel core-shell structure fuel cell catalyst comprises adding carbon powder and surfactant to organic solvent and mixing; adding nickel compound and mixing; microwave irradiating at 80-800 degrees C for 0.01-120 minutes, standing, and cooling; adding molybdenum compound and mixing; and microwave irradiating at 80-800 degrees C for 0.01-120 minutes, standing, cooling, washing with distilled water, ethanol or acetone, and drying.    USE - Method for preparing molybdenum nickel core-shell structure fuel cell catalyst (claimed).    ADVANTAGE - The catalyst when compared with commercial platinum catalyst has comparable carbon content, excellent performance, and electron transfer close to 4.    DETAILED DESCRIPTION - Preparation of molybdenum nickel core-shell structure fuel cell catalyst comprises:    (A) adding carbon powder and surfactant to organic solvent and mixing to obtain first mixture, where mass ratio of solvent and carbon powder is 1-2968:1, mass ratio of surfactant to carbon powder is 0.1-50:1, and organic solvent is methanol, ethanol, ethanediol, or glycerol;    (B) adding nickel compound and mixing, where mass ratio of carbon powder to nickel is 0.53-50:1 and nickel compound is nickel nitrate hexahydrate, nickel acetate, nickel carbonate, nickel chloride, nickel sulfate, basic nickel carbonate, nickel oxide, or nickelous oxide;    (C) microwave irradiating at 80-800 degrees C for 0.01-120 minutes, standing, and cooling;    (D) adding molybdenum compound and mixing, where mass ratio molybdenum to carbon powder is 0.21-50:1 and molybdenum compound is molybdenum fluoride, molybdenum nitrate, molybdenum phthalocyanine, molybdenum oxide, sodium chlorine molybdate, molybdenum chloride, molybdenum dichloride, molybdenum tetrachloride, chlorine molybdate, or potassium chloride molybdate; and    (E) microwave irradiating at 80-800 degrees C for 0.01-120 minutes, standing, cooling, washing with distilled water, ethanol or acetone, and drying.
