MANUFACTURING METHOD OF LIQUID CURING RESIN COMPOSITION FOR ELECTROLYTE FILM AND ELECTROLYTE FILM, AND MANUFACTURING METHOD OF ELECTROLYTE FILM/ELECTRODE ASSEMBLY

摘要

PPROBLEM 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. PSOLUTION: 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 25C 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.
