发明名称 METHOD FOR PRODUCING ELECTRODE CATALYST FOR FUEL CELLS, ELECTRODE CATALYST FOR FUEL CELLS, AND USE OF SAME
摘要 Provided is a process for producing a fuel cell electrode catalyst with high catalytic activity that is alternative to a noble metal catalyst, through a heat treatment at a relatively low temperature. A process for producing a fuel cell electrode catalyst includes a step (I) of obtaining a catalyst precursor, including a step (Ia) of mixing at least a metal compound (1), a nitrogen-containing organic compound (2), and a fluorine-containing compound (3), and a step (II) of heat-treating the catalyst precursor at a temperature of 500 to 1300°C to obtain an electrode catalyst, a portion or the entirety of the metal compound (1) being a compound containing an atom of a metal element M1 selected from the group consisting of iron, cobalt, chromium, nickel, copper, zinc, titanium, niobium and zirconium, and at least one of the compounds (1), (2) and (3) containing an oxygen atom.
