A method for supporting a catalyst for a polymer electrolyte fuel cell is characterized in that the method for supporting a catalyst includes the steps of making a catalyst layer (12, 14) including a catalyst precursor, the catalyst layer to be used as either an anode catalyst layer (12) or a cathode catalyst layer (14), arranging the catalyst layer with a polymer electrolytic membrane (13) having proton conductivity in a thickness direction, and performing an electrochemical reductive reaction for reducing the catalyst precursor included in the catalyst layer to produce a catalyst and concomitantly developing a catalyst particle layer (13k) having a plurality of catalyst microparticles in the polymer electrolytic membrane. |
