Ion exchange membrane for electrolysis |
摘要 |
An ion exchange membrane for electrolysis comprising a first layer of a fluoropolymer having carboxylic acid groups as its ion exchange groups and facing a cathode, a second layer of a fluoropolymer having ion exchange groups, a specific resistance lower than that of the first layer and a thickness of at least 50% of the total thickness of the membrane, and a third layer of a fluoropolymer having ion exchange groups, a swelling degree higher by at least 5% than that of the second layer and a specific resistance lower by at least 30 OMEGA .cm than that of the second layer, the first, second and third layers being laminated in this order.
