Title:
ANIONIC EXCHANGE RESIN, ELECTROLYTE LAYER FOR FUEL CELL, BINDER FOR FORMING ELECTRODE CATALYST LAYER, CELL ELECTRODE CATALYST LAYER, AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2014/050928
Kind Code:
A1
Abstract:
The present invention provides: an anionic exchange resin that is able to produce an exceptionally durable electrolyte layer for a fuel cell, binder for forming an electrode catalyst layer, and cell electrode catalyst layer; an electrolyte layer for a fuel cell, binder for forming an electrode catalyst layer, and cell electrode catalyst layer formed from the anionic exchange resin; and a fuel cell provided with the electrolyte layer for a fuel cell or the cell electrode catalyst layer. Hydrophobic units are bonded to hydrophilic units with ether bonds; in the hydrophobic units there repeat, interposed by ether bonds, bivalent hydrophobic groups comprising a plurality of aromatic rings bonded to each other with a bivalent saturated hydrocarbon group interposed therebetween, and bivalent bonding groups comprising a single aromatic ring or a plurality of aromatic rings bonded to each other with a carbon-carbon bond interposed therebetween; and in the hydrophilic units there repeat, interposed by ether bonds, bonding groups and bivalent hydrophilic groups comprising a plurality of aromatic rings having an anionic exchange group, the aromatic groups being bonded to each other with an oxygen or a sulfur atom interposed therebetween.
