Abstract: The present invention relates to a highly conductive anion exchange composite membrane filled with crosslinked polymer electrolytes for an alkali fuel cell and a novel manufacturing method thereof. The present invention provides a method for manufacturing an anion-conducting composite membrane filled with crosslinked polymer electrolytes, comprising the steps of: (A) mixing and churning (vinylbenzyl)trimethylammonium chloride, 1,3,5-triacryloylhexahydro-1,3,5-triazine, and a solvent, which is made by mixing deionized water and dimethylformamide in a weight ratio of 1:1, in a weight ratio of 60-75 : 5-16 : 20-25; (B) mixing 0.5 to 2 parts by weight of a photoinitiator with respect to 100 parts by weight of the mixed solution; (C) permeating a porous support with monomer solution by impregnating the support with the solution; (D) crosslinking an electrolyte-impregnated membrane by inserting the electrolyte-impregnated membrane in a polyethylelenterephthalate (PET) film and irradiating the electrolyte-impregnated membrane with ultraviolet rays at an intensity of 30 to 150 mJ/cm^2; and (E) removing the PET film, removing byproduct on the surface of the membrane and washing the membrane after the crosslinking step. The anion-conducting composite membrane filled with crosslinked polymer electrolytes according to the present invention can be used widely in the industrial field of fuel cells including solid alkali fuel cells as the composite membrane has excellent hydroxide ion conductivity.
