<P>PROBLEM TO BE SOLVED: To provide a fuel preventing flooding in a cathode. <P>SOLUTION: A film electrode joint body (1) in a fuel cell is provided with a solid polymer film (10) capable of generating power by being supplied air and hydrogen. The film electrode joint body (1) is provided with a cathode catalyst layer (21) formed on one surface of the solid polymer film (10), and cathode dispersion layers (22, 23) laminated on the cathode catalyst layer (21). Water repellence of the cathode catalyst layer (21) is higher than that in either regions of cathode dispersion layers (22, 23), and a slope of water repellence from the cathode catalyst layer (21) to the cathode dispersion layers (22, 23) is greater on an air supplying side than on an air exhausting side in the film electrode joint body (1). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
