POLYMERIC LAMINATES, PROCESSES FOR PRODUCING THE SAME, AND USE THEREOF

摘要

A laminated membrane consisting of a membrane (I) made of an aromatic polymer electrolyte having superstrong acid groups and a membrane (II) made of one member selected from the group consisting of perfluoroalkylsulfonic acid polymer electrolytes and non-superstrong acid polymer electrolytes; and a laminated membrane constituting of a membrane (III) made of a perfluoroalkylsulfonic acid polymer electrolyte and a membrane (IV) made of a non-superstrong acid polymer electrolyte. These laminated membranes are useful as electrolyte membranes excellent in power generation performance and mechanical strengths.
