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.

Usage and Storage Recommendations

Pretreatment Methods (By Application)

Application Scenario	Recommended Wetting/Activation Method	Notes
Fuel Cell / Redox Flow Battery	Soak in 0.5 M NaCl, 24–72 h	Promotes swelling and stabilizes dimensional stability
Electrodialysis / Acid-Base Recovery	Soak in NaCl or KCl solution, 12–48 h	Avoids bubble entrainment
CO₂ Electroreduction / Water Electrolysis	Convert to OH⁻ form: Soak in 0.5–1.0 M NaOH or KOH ≥ 24 h	Operation under inert atmosphere is preferred
Long-term Storage	Store in a dry, hermetically sealed, light-proof container	Prevents moisture and CO₂ from degrading performance
Short-term Storage	Immerse in neutral saline solution in a sealed container	Suitable for pre-wetted membranes

Non-product quality problem, no return
