<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a fuel cell preventing wrinkles of an electrolyte film as well as wrinkles and cracks of an electrode by restraining swelling of the electrolyte film, in forming an electrode by directly coating slurries on the surface of the electrolyte film and drying them. <P>SOLUTION: In the manufacturing method of the fuel cell including a coating process of coating slurries containing at least a polymer material and a solvent on an electrolyte film, and an ambient temperature at the coating process is such a temperature that, out of solvent component, saturated vapor pressure of the solvent component having at least the highest volatility is 80 kPa or more. <P>COPYRIGHT: (C)2007,JPO&INPIT |
