Overview

Details

This anion exchange membrane, Fumasep FAA-3-20, is designed for use in electrochemical systems, including fuel cells and energy-related separation processes. With a thickness of approximately 18 to 22 µm and a brown transparent film appearance, the membrane exhibits low resistance (under 2.0 Ω/cm² in chloride form) and high ionic selectivity exceeding 90%. It is supplied in a dry state and requires self-activation prior to use. The material demonstrates strong stability in acidic and alkaline environments, making it suitable for applications that demand reliable ion transport and selective separation. This product supports research and development in advanced energy materials, particularly where efficient anion exchange and durability under varying chemical conditions are needed.
