Method for producing fuel cell electrode catalyst, fuel cell electrode catalyst, and uses thereof |
摘要 |
A method for producing a fuel cell electrode catalyst, including: a step (1) of mixing at least a metal compound (1), a nitrogen-containing organic compound (2), a compound (3) containing fluorine and at least one element A selected from the group consisting of boron, phosphorus, and sulfur, and a solvent to obtain a catalyst precursor solution, a step (2) of removing the solvent from the catalyst precursor solution, and a step (3) of heat-treating a solid residue, obtained in the step (2), at a temperature of 500 to 1100° C. to obtain an electrode catalyst; a portion or the entirety of the metal compound (1) being a compound containing, as a metal element, at least one transition metal element M1 selected from the elements of group 4 and group 5 of the periodic table; and at least one of the compounds (1), (2), and (3) having an oxygen atom. |
