<P>PROBLEM TO BE SOLVED: To provide a fuel cell satisfying both of prevention of CO poisoning of a Pt-Ru catalyst and prevention of contamination of an electrolyte membrane. <P>SOLUTION: In the fuel cell formed by stacking an anode side diffusion layer 13, an anode side catalyst layer 14, an electrolyte membrane 11, a cathode side catalyst layer 17, a cathode side diffusion layer 16 in order, the anode side catalyst layer contains the Pt-Ru catalyst, a catalyst layer part 14a apart from the electrolyte membrane out of the anode side catalyst layer and/or the anode side diffusion layer 13 contain/contains a metal element 50 having standard electrode potential lower than Ru and higher than hydrogen, and the metal element 50 is at least one element selected from the group comprising Cu, Re, and Ge. <P>COPYRIGHT: (C)2007,JPO&INPIT |
