<P>PROBLEM TO BE SOLVED: To provide a new method for preventing a polymer electrolyte material from being decomposed by a radical resulting from hydrogen gas, which has passed through an electrolytic film, in an air electrode side catalyst layer of a fuel cell. <P>SOLUTION: The air electrode side catalyst layer has a first catalyst layer on a side of the electrolytic film and a second catalyst layer on a side of a diffusion layer, where a gas transfer resistance of the first catalyst layer is higher than a gas transfer resistance of the second catalyst layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
