Alkaline Water Electrolysis Composite Membrane, AWE-500S, 500 μm (CAT#: STEM-BC-0129-ZJF)

The alkaline water electrolysis composite membrane is a high-performance separator designed for hydrogen generation via alkaline electrolysis. Its gradient pore structure provides excellent gas separation, preventing hydrogen-oxygen mixing and achieving 99.9% hydrogen purity. The membrane exhibits excellent hydrophilicity for rapid ion transport, reducing energy consumption. It is chemically stable under concentrated alkaline conditions and maintains performance at elevated temperatures. Two thickness options accommodate different electrolysis configurations. The membrane provides high tensile strength and dimensional stability. Electrical resistance and ion exchange characteristics support efficient electrolytic operation.
