CROSS-LINKED POLYMER ELECTROLYTE MEMBRANE, MEMBRANE ELECTRODE ASSEMBLY USING IT, ITS MANUFACTURING METHOD, AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a cross-linked polymer electrolyte membrane having a high proton conductivity and a high water resistance capable of using for a solid polymer fuel cell and a direct methanol type fuel cell and its manufacturing method, a membrane electrode assembly using the cross-linked polymer electrolyte membrane and its manufacturing method, and a fuel cell having the membrane electrode assembly.

SOLUTION: This is the cross-linked polymer electrolyte membrane formed as a main component of a cross-linked polymer 100 which is obtained by cross-linking reaction of a proton conductive polymer (a) having a proton acid group (c) and a cross-linking agent (b) through a portion other than the proton acid group (c). The proton conductive polymer is made of an aromatic system polymer.
