SOLID POLYMER ELECTROLYTE MEMBRANE, METHOD FOR PRODUCING THE SAME AND FUEL CELL

Title:

SOLID POLYMER ELECTROLYTE MEMBRANE, METHOD FOR PRODUCING THE SAME AND FUEL CELL

Document Type and Number:

Japanese Patent JP2006291059

Kind Code:

A

Abstract:

To provide a solid polymer electrolyte membrane having higher proton conductivity and smaller methanol permeability simultaneously, and a high performance fuel cell.

This solid polymer electrolyte membrane is obtained by irradiating a fluorine-based resin thin membrane with a radiation for graft polymerizing a monofunctional monomer and then irradiating the copolymer with the radiation again for graft polymerizing a multi-functional monomer. Also, the fuel cell is obtained by installing the solid polymer electrolyte membrane between a fuel electrode and an air electrode.
