Anion Exchange Membrane (AEM)

Product Overview

The anion exchange membrane is a high-performance homogeneous membrane material designed for high-temperature and highly alkaline environments. It features high ionic conductivity, excellent mechanical strength, and outstanding chemical stability. Widely used in water electrolyzers, alkaline fuel cells, and CO₂ reduction systems, this membrane maintains excellent performance under harsh conditions, ensuring long-term durability and providing reliable support for efficient electrochemical reactions.

Working Principle

The membrane forms stable anion-conducting channels through its anion exchange groups, enabling efficient anion transport and ensuring high electrochemical reaction efficiency. Its homogeneous structure and mechanical robustness allow the membrane to maintain dimensional stability and structural integrity during long-term operation under high temperature and alkaline conditions, while also preventing unwanted side reactions and extending service life.
