<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a fuel cell excellent in jointing performance of a solid electrolyte membrane and a catalyst electrode layer. <P>SOLUTION: The manufacturing method of a solid polymer electrolyte fuel cell comprises a forming process of a solid electrolyte membrane to form a solid electrolyte membrane having as a main component a first hydrocarbon system electrolyte resin, a catalyst electrode layer forming process to form a catalyst electrode layer including a first fluorine system electrolyte resin, an adhesive layer forming process to form an adhesive layer containing a second hydrocarbon system electrolyte resin with lower glass transition temperature than the first hydrocarbon system electrolyte resin and a second fluorine system electrolyte resin on at least one of the solid electrolyte membrane and the catalyst electrode layer, and a jointing process to joint the solid electrolyte membrane and the catalyst electrode layer through the adhesive layer. The jointing process is carried out by thermo-compression bonding at a temperature higher than the glass transition temperature of the second hydrocarbon system electrolyte resin and the temperature lower than the glass transition temperature of the first hydrocarbon system electrolyte resin. <P>COPYRIGHT: (C)2008,JPO&INPIT |
