Abstract
Official abstract text for this publication.
A method is provided for producing a platinum alloy-containing fuel cell electrode catalyst with high activity which is suited for its industrial mass-production. The method for producing a fuel cell electrode catalyst includes a step of preparing a dispersion in which particles of a fuel cell electrode catalyst precursor including a platinum alloy is dispersed in an electrolyte solution, and a step of alternately subjecting the dispersion to bubbling with an oxidizing gas and to bubbling with an inert gas or a reducing gas.
First claim
Opening claim text (preview).
1 . A method for producing a fuel cell electrode catalyst comprising: a step of preparing a dispersion in which a fuel cell electrode catalyst precursor comprising a platinum alloy is dispersed in an electrolyte solution, and a step of alternately subjecting the dispersion to bubbling with an oxidizing gas and to bubbling with an inert gas or a reducing gas. 2 . The method for producing a fuel cell electrode catalyst described in claim 1 , wherein the electrolyte solution is an aqueous sulfuric acid solution, an aqueous perchloric acid solution, hydrochloric acid or an aqueous nitric acid solution. 3 . The method for producing a fuel cell electrode catalyst described in claim 1 , wherein the oxidizing gas is an oxygen gas. 4 . The method for producing a fuel cell electrode catalyst described in claim 1 , wherein the inert gas or the reducing gas is an inert gas. 5 . The method for producing a fuel cell electrode catalyst described in claim 4 , wherein the inert gas is nitrogen gas.
