ELECTROLYTE MEMBRANE FOR SOLID POLYMER TYPE FUEL BATTERY, SOLID POLYMER TYPE FUEL BATTERY AND METHOD OF MANUFACTURING ELECTROLYTE MEMBRANE FOR SOLID POLYMER TYPE FUEL BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte membrane that enables a solid polymer type fuel battery to operate under a high temperature condition and a low humidity condition.SOLUTION: An electrolyte membrane for a solid polymer type fuel battery is obtained by bonding an ion exchange group to a graft chain of aromatic hydrocarbon-based polymer resin containing inorganic filler. Aromatic hydrocarbon polymer type polymer resin is preferably polyether ether ketone or a derivative thereof. The solid polymer type fuel battery contains a membrane electrode assembly obtained by bonding a fuel electrode to one membrane surface of the electrolyte membrane for the solid polymer type fuel battery, and bonding an air electrode to the other membrane surface.SELECTED DRAWING: Figure 1
