Anion Exchange Membrane
A selectively permeable anion exchange membrane that transports negatively charged ions (OH⁻, CO₃²⁻, HCO₃⁻) while preventing reactant crossover, ensuring efficient ion conduction and charge balance.
It offers high conductivity, mechanical stability, and alkaline resistance, making it ideal for water electrolysis, CO₂ electroreduction, and fuel cell applications.
Description
An anion exchange membrane (AEM) is a selectively permeable membrane designed to transport negatively charged ions (anions) such as OH⁻, CO₃²⁻, and HCO₃⁻ while preventing the mixing of reactants between compartments. It plays a critical role in maintaining ionic conductivity and charge balance in electrochemical systems.
Constructed from chemically stable polymer materials, AEMs offer high ion conductivity, good mechanical strength, and resistance to alkaline environments. They are widely used in applications such as water electrolysis, CO₂ electroreduction, and fuel cells, where efficient ion transport and separation are essential for performance and stability.
