Method for producing anion exchange membrane for solid polymer electrolyte fuel cell

摘要

Provided is a method for the simple and stable production of an anion exchange membrane for an anion exchange membrane-type fuel cell. An anion-exchange membrane having quaternary ammonium groups or quaternary phosphonium groups wherein halogen ions serve as the counter ions is obtained and rather than being subjected to ion exchange with an OH-type membrane using a toxic substance such as sodium hydroxide, the halogen-type anion exchange membrane is brought into contact with a carbonate solution and/or bicarbonate solution to directly obtain an anion exchange membrane where at least some of the counterions of the quaternary ammonium groups or quaternary phosphonium groups are CO 3 2- and/or HCO 3 - .
