<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell capable of maintaining high power generation property for a long period. <P>SOLUTION: The solid polymer fuel cell (150) composed of a catalyst layer (120a, 120c) formed by laminating a catalyst layer (1) (121a, 121c) free from cracks and a catalyst layer (2) (122a, 122c) having cracks (123a, 123c), and average diameter of catalyst particles contained in the catalyst layer (120a, 120c) becomes larger as it is headed from inlet side to outlet side of a gas flow passage (141) of separators (140a, 140c). <P>COPYRIGHT: (C)2007,JPO&INPIT |
