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 CO32- and/or HCO3-.
本发明提供了一种用于阴离子交换膜燃料电池的阴离子交换膜的简单而稳定的生产方法。这种阴离子交换膜具有季铵盐基团或季鏻基团,其中卤素离子可作为反离子,而且这种卤素型阴离子交换膜无需使用氢氧化钠等有毒物质与 OH 型膜进行离子交换,而是与碳酸盐溶液和/或碳酸氢盐溶液接触,从而直接获得一种阴离子交换膜,其中季铵盐基团或季鏻基团的反离子至少有一部分是 CO32- 和/或 HCO3-。
