Title:
CROSSLINKED POLYMER ELECTROLYTE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2006/107115
Kind Code:
A1
Abstract:
Disclosed is a crosslinked polymer electrolyte obtained by the process (1) or (2) below. This crosslinked polymer electrolyte can be produced at low cost, and has excellent water resistance, excellent solvent resistance, high heat resistance and low methanol permeability. This crosslinked polymer electrolyte is therefore suitable for a proton conducting membrane of fuel cells. Also disclosed is a method for producing such a crosslinked polymer electrolyte. (1) A compound having two or more reactive groups is reacted with a polymer electrolyte. (2) A crosslinked polymer is obtained by reacting a compound having two or more reactive groups with a polymer, and an ion-exchange group is introduced into the thus-obtained crosslinked polymer.
