<P>PROBLEM TO BE SOLVED: To provide a catalyst layer increasing mechanical strength such as mar resistance and hardness without damaging physical properties necessary for the catalyst layer for a fuel cell as typified in proton conductivity and gaseous diffusion properties; and to provide a method for forming the same. <P>SOLUTION: The catalyst layer for a polymer electrolyte fuel cell having a crosslinking polymer skeleton formed by polymerizing a cationic polymerizable monomer in the catalyst layer is formed by: forming the catalyst layer with catalyst slurry containing catalyst particles, a polymer electrolyte, and the cationic polymerizable monomer and not containing a polymerization initiator; and polymerizing the cationic polymerizable monomer by applying heat energy to the catalyst layer. <P>COPYRIGHT: (C)2010,JPO&INPIT |
