<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a liquid curing resin composition for an electrolyte film superior in ion conductivity, of the electrolyte film high in productivity, and of the electrolyte film/electrode assembly which can be adhered excellently without heat-pressing the electrolyte film and the electrode. <P>SOLUTION: This is the liquid curing resin composition for the electrolyte film which contains a compound having at least one ethylenic unsaturated group, at least one ion conductive group, or its precursor group in one molecule, and in which viscosity at 25°C is 100,000 mPas or less. By this, the liquid curing resin composition for the electrolyte film which can become a curing film superior in ion conductivity, the electrolyte film for the fuel cell which simultaneously satisfies characteristics such as productivity, ion conductivity, and film strength, and the electrolyte film/electrode assembly for the fuel cell can be obtained. Because the electrolyte film for the fuel cell manufactured by this method can make a film thickness thinner, the superior ion conductivity can be obtained, and it becomes particularly useful as the electrolyte film for a solid polymer fuel cell and a direct methanol type fuel cell. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
