ANION EXCHANGE COMPOSITE MEMBRANE, MANUFACTURING METHOD THEREFOR, AND ALKALINE FUEL CELL COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2022/270934

Kind Code:

A1

Abstract:

The present invention relates to techniques for manufacturing an anion exchange composite membrane and applying the membrane to alkaline fuel cells, water electrolysis, redox flow batteries, and the like, the membrane comprising: a porous support containing polyphenylenesulfide; and an anion exchange layer prepared from a composition, which is filled in the support and contains an anion exchange polymer. The anion exchange composite membrane comprising the porous support according to the present invention has significantly improved mechanical properties, dimensional stability, durability, chemical stability, and long-term stability.
