Abstract
(EN)
[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.

L’invention a pour but de fournir un échangeur d'anions qui peut être utilisé comme agent conférant une conductivité ionique qui est utilisé dans une pile à combustible et un appareil d'électrolyse de l'eau qui utilise une membrane d'échange d'anions, et qui peut obtenir un bon équilibre entre la résistance à la chaleur, l'insolubilisation et l'augmentation de la capacité d'échange d'ions de l'agent conférant une conductivité ionique. Selon l’invention, la résistance à la chaleur est conférée à l'aide d'un polymère de styrène, la longueur de chaîne d'un groupe alkyle entre un groupe d'échange d'ions et un noyau aromatique étant étendue, et un bon équilibre entre l'insolubilisation et la capacité élevée d'échange d'ions peut être obtenu à l'aide d'une structure réticulée qui possède un groupe ammonium quaternaire en tant que groupe d'échange d'ions.
