Abstract
Official abstract text for this publication.
The present invention is to provide a method for producing a core-shell catalyst for fuel cells, which is configured to facilitate shell deposition by, at the time of shell deposition, decreasing an oxidation-reduction potential lower than ever before. Disclosed is a method for producing a core-shell catalyst for fuel cells, wherein the method comprises: a bubbling step of bubbling hydrogen into a mixture A containing a core fine particle-supported carbon and alcohol; a first refluxing step of refluxing the mixture A after the bubbling step; a mixing step of preparing a mixture B by, after the first refluxing step, mixing the mixture A having a temperature that is lower than that in the first refluxing step with a shell material; and a second refluxing step of refluxing the mixture B.
