ANION EXCHANGE RESIN, ELECTROLYTE MEMBRANE, BINDER FOR FORMING ELECTRODE CATALYST LAYER, AND BATTERY ELECTRODE CATALYST LAYER

Document Type and Number:

WIPO Patent Application WO/2024/014280

Kind Code:

A1

Abstract:

Provided are: an anion exchange resin that makes it possible to produce an electrolyte membrane, a binder for forming an electrode catalyst layer, and a battery electrode catalyst layer having exceptional electrical properties (anion conductivity) and chemical properties (gas permeability and water containability); an electrolyte membrane and a binder for forming an electrode catalyst layer that are formed from the anion exchange resin; and a battery electrode catalyst layer that is formed from the binder for forming an electrode catalyst layer.　For example, there is used an anion exchange resin configured such that a hydrophobic unit in which divalent hydrophobic groups containing a bisphenol residue having an alicyclic structure are repeated via carbon-carbon bonds, a hydrophobic unit in which divalent hydrophobic groups composed of a plurality of aromatic rings bonded to each other via divalent fluorine-containing hydrocarbon groups are repeated via carbon-carbon bonds, and a hydrophilic unit having a fluorene ring that bonds with an anion-exchange-group-containing group, are bonded via carbon-carbon bonds.
