Title:
SOLID POLYMER ELECTROLYTE MEMBRANE, METHOD FOR PRODUCING SAME, AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2006/120871
Kind Code:
A1
Abstract:
Disclosed is a high-performance solid polymer electrolyte membrane which is excellent in mechanical strength, chemical stability and dimensional stability while being decreased in methanol permeability. This solid polymer electrolyte membrane is obtained by radiation graft polymerization without causing gelation of the solution. Such a solid polymer electrolyte membrane is obtained by graft polymerizing a polymerizable monomer having an alkoxysilyl group by itself or the polymerizable monomer having an alkoxysilyl group together with another polymerizable monomer onto a resin film which is irradiated with radiation, and then subjecting the alkoxysilyl group to hydrolysis and dehydration condensation. A fuel cell is obtained by arranging such a solid polymer electrolyte membrane between a fuel electrode and an air electrode.
