Method for producing membrane-electrode assembly for fuel cell |
摘要 |
Disclosed is a method for removing a solvent ( 41 ) in an electrolyte membrane ( 24 ) as a constituent of a membrane-electrode assembly ( 12 ) used in a fuel cell. The membrane-electrode assembly is arranged in a water vapor, and the water vapor is introduced into the electrolyte membrane by being transmitted through diffusion layers ( 21, 27 ) respectively on positive/negative electrode sides. The solvent in the electrolyte membrane is removed by the thus-introduced water vapor. This removal of the solvent is performed at temperatures which are not higher than the decomposition temperature of the hydrocarbon solid polymer.
