MANUFACTURING METHOD FOR AROMATIC POLYETHER ELECTROLYTE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for an electrolyte membrane that exhibits high proton conductance and high water resistance even when density of an ion exchange group is increased.

SOLUTION: A monomer requiring aromatic polyether having a vinyl group at an end and an ion exchange group in a molecule is impregnated into a pore of a porous base material having the swelling-resistant property. Subsequently, radical copolymerization of the vinyl group generates an electrolyte resin having ion exchange property and cross-linking in the pore of the porous base material to manufacture an electrolyte membrane filled with the electrolyte resin.
