Selective Anion Transport: It can selectively transport anions (such as hydroxide ions OH⁻), thereby achieving efficient electrochemical processes.

Gas Separation: It can effectively isolate the hydrogen gas produced at the cathode and the oxygen gas produced at the anode, preventing dangerous gas mixtures.

Enhanced Hydrogen Purity: In hydrogen production, AEM ensures that hydroxide ions smoothly pass from the cathode to the anode, resulting in high-purity hydrogen, which is crucial for applications like fuel cells.

Features: High ionic selectivity, high electrical conductivity, high chemical stability, low membrane resistance, excellent mechanical strength, and flexibility.
