Title:
ANION EXCHANGER, ION CONDUCTIVITY-IMPARTING AGENT, CATALYST ELECTRODE LAYER, MEMBRANE-ELECTRODE ASSEMBLY, ANION EXCHANGE MEMBRANE FUEL CELL AND ANION EXCHANGE MEMBRANE WATER ELECTROLYSIS APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/022775
Kind Code:
A1
Abstract:
[Problem] To provide an anion exchanger which is able to be used as an ion conductivity-imparting agent that is used in a fuel cell and a water electrolysis apparatus that use an anion exchange membrane, and which is capable of achieving a good balance among heat resistance, and insolubilization and ion exchange capacity increase of the ion conductivity-imparting agent.
[Solution] Heat resistance is imparted by using a styrene polymer wherein the chain length of an alkyl group between an ion exchange group and an aromatic ring is extended, and a good balance between insolubilization and high ion exchange capacity is able to be achieved by using a crosslinked structure that has a quaternary ammonium group as an ion exchange group.
