<P>PROBLEM TO BE SOLVED: To improve contact of a stacking surface between a membrane electrode and a catalyst layer without executing a surface softening treatment of the electrolyte membrane by heat transfer or heat press and thereby to provide a high-performance membrane electrode assembly. <P>SOLUTION: This method is used for manufacturing this membrane electrode assembly formed by stacking the catalyst layer on the electrolyte membrane. Catalytic substance-containing ink containing a catalytic substance, an ion exchange resin and a solvent containing water as a main constituent is used, the catalytic substance-containing ink is directly applied to the electrolyte membrane installed on a stage by a spray method, and thereafter the solvent is volatilized to form the catalyst layer. Preferably, heating of the stage and suction from the undersurface thereof are executed at the same time. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
