<P>PROBLEM TO BE SOLVED: To provide a carrying catalyst for a fuel cell that is effective for obtaining higher output of the fuel cell. <P>SOLUTION: This is the carrying catalyst for the fuel cell provided with platinum, transition metal element other than platinum, rare earth element, and a conductive carrier carrying them. This carrying catalyst is for the fuel cell provided with alloy of platinum, transition metal element other than platinum, and rare earth element, and with a conductive carrier for carrying the alloy. If the carrying catalyst 5b is used at the cathode catalyst layer 3, oxygen molecules can be reduced efficiently to oxygen ions, and a membrane electrode assembly of higher output can be obtained, as compared with the case in which platinum or platinum alloy is used as the cathode catalyst 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
