Abstract

Provided is a method of producing a fuel cell catalyst layer which has a large specific surface area and high activity and which includes the steps of: forming a dendritic structural member including a catalyst precursor by a vapor phase method; providing a coating layer on a surface of the dendritic structural member; and subjecting the dendritic structural member having the coating layer provided thereon to a reduction treatment. The dendritic structural member including a catalyst precursor is a dendritic structural member including platinum oxide or a dendritic structural member containing a composite oxide of platinum oxide and an element except platinum.
