FS-960-RF - Electrolyser Membrane

FUMATECH BWT GmbH

Suitable for electrochemical processes like Water Electrolysis and Redox-Flow Batteries
Ready for use without pretreatment
High conductivity
High selectivity
High mechanical stability

The FS-960-RF is a fluorinated cation-exchange membrane with a reinforced structure, offering low resistance, high mechanical stability, and excellent performance in acidic environments. It is specifically designed for electrochemical processes such as water electrolysis and redox-flow batteries. The membrane is delivered as a transparent foil on a colorless rigid PET backing layer and requires careful handling to avoid damage. It is ready for use without pretreatment and provides high conductivity, low dimensional swelling, and strong oxidative stability. The membrane has a thickness of 54–66 μm, a weight per unit area of 136–142 mg/cm², and an ion exchange capacity of 1.15 meq/g. It is suitable for applications requiring high oxidative stability and is available in a dry form for immediate use.

Use Cases
