<P>PROBLEM TO BE SOLVED: To provide a film-electrode junction for solid polymer fuel cell generating power with high energy efficiency, having high power generating property regardless of dew point of supplied gas, and stably generating power for long period. <P>SOLUTION: A cation exchange film, containing a polymer compound containing sulfonic acid group and insoluble cerium compound, is used as an electrolyte film for solid polymer fuel cell. On the cation exchange film, preferably, the content of insoluble cerium compound is 0.3 to 80% to the total mass of the cation exchange film, and perfluorocarbon polymer having sulfonic acid group is used as the polymer compound. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
