Abstract
An electrolyte membrane for fuel cells is prepared by irradiating with radiation a composition comprising a radiation-curable liquid compound having proton conductivity for curing the liquid compound to form a cured film. The methods of the invention are successful in producing an electrolyte membrane and an electrolyte membrane/electrode assembly for fuel cells while satisfying both the requirements of productivity and cell-related properties including proton conduction and membrane strength.
