<P>PROBLEM TO BE SOLVED: To provide a catalyst layer-electrolyte membrane laminate with reinforcement film improved in discharge performance of generated water, a membrane electrode assembly with reinforcing film, and a solid polymer fuel cell. <P>SOLUTION: The catalyst layer-electrolyte film, laminated with reinforcing film is provided with a catalyst layer-electrolyte film laminate 10, in which a catalyst layer 3 is formed on both sides of an ion conductive polymer electrolyte membrane 2 and a reinforcing film 4, which adheres to both sides of the catalyst layer-electrolyte membrane laminate 10, in a state where the opening part 41 is formed at the center, and the inner periphery portion is mounted on the outer periphery portion 31 of the catalyst layer 3. The reinforcing film 4 has a water repellent layer 44 on the inner periphery face which demarcates the opening part 41. <P>COPYRIGHT: (C)2011,JPO&INPIT |
