NOVELTY - Proton exchange membrane fuel cell cathode non-platinum catalyst is new, where the catalyst is prepared by adding e.g. formaldehyde and isobutyl alcohol and stirring, adding melamine, phthalic anhydride to the mixture, decompressing, dehydrating and filtering the mixture, adding e.g. Pluronic F127 (RTM: Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) copolymer) and ethanol and stirring with tetraethyl orthosilicate, obtained resin and ethanol, placing product with transition metal salt into dish, hot polymerizing and grinding obtained film into powder.    USE - Used as proton exchange membrane fuel cell cathode non-platinum catalyst.    ADVANTAGE - The catalyst is prepared in simple and cost-effective manner, and has good oxygen reduction activity.    DETAILED DESCRIPTION - Proton exchange membrane fuel cell cathode non-platinum catalyst, is new, where the catalyst is prepared by: (a) adding 37 ml of formaldehyde, 40 ml of isobutyl alcohol, and 1 g of magnesium carbonate, stirring the mixture while heating, adding melamine to the mixture, adding 0.07 g of phthalic anhydride to the mixture at 60-100 degrees C for 30-120 minutes, and decompressing, dehydrating and filtering the mixture to obtain milky white gel melamine formaldehyde resin; (b) adding 15 g of Pluronic F127 (RTM: Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) copolymer), 10-20 g of ethanol and 14 g of 0.2 mole hydrochloric acid solution, heating the mixture at 40-50 degrees C for 0.5-1 hours and stirring, adding 3-8 g of tetraethyl orthosilicate and the obtained melamine formaldehyde resin and ethanol to the mixture, adding transition metal salt to the mixture, stirring the mixture at 40-50 degrees C for 1-2 hours to obtain a product; (c) adding the obtained product into evaporating dish at room temperature, placing the dish in oven at 80-100 degrees C for 12-24 hours to perform hot polymerization and obtain light yellow film, scraping and grinding the film into powder; and (d) performing first heat treatment process on the powder using a tubular furnace, adding the powder to 10% of hydrofluoric acid solution for 12-24 hours, centrifuging the mixture and washing the supernatant using water for 4 times and then drying, and performing second heat treatment process on the dried powder using a tubular furnace and the mole ratio of melamine and formaldehyde is 1:3.7, the mass ratio of melamine formaldehyde resin to ethanol is 1:1-10, and the mole ratio of transition metal salt to the melamine formaldehyde resin is 1:1-20.
