Description Vendor

The FS-930-RFS is a fluorinated cation-exchange membrane specifically designed for use in fuel cell applications (H2-PEMFC). It is characterized by its low electrical resistance, high mechanical stability, low dimensional swelling, and exceptional stability in acidic environments. The membrane is supplied as a transparent, light brown foil on a backing layer of colorless rigid PET foil and is ready for use without any pretreatment. It exhibits excellent performance with an area resistance of less than 0.02 Ω cm² at 25°C in H-form and high tensile strength, making it ideal for fuel cell systems. The membrane is also durable and resistant to punctures and scratches, ensuring reliable operation in demanding conditions.

Use Cases

  • Fuel Cell application (H2-PEMFC)

Capabilities

  • Ready for use without pretreatment
  • High mechanical stability
  • Low dimensional swelling (<6% in H2O at 25 °C)
  • High Young’s modulus at 23 °C / 50 % r.h. (>250 MPa)
  • High tensile strength (>20 MPa)
  • High burst test in water at 25 °C (>3 bar)
  • High elongation at break (>150%)
FUMATECH BWT GmbH FUMATECH BWT GmbH, a subsidiary of the BWT Group headquartered in Bietigheim-Bissingen, Baden-Württemberg, Germany, specializes in innovative ion-exchange membrane technology serving two key electrochemical application fields: water treatment and energy-related applications including PEM fuel cells, water electrolysis, and redox-flow batteries. Drawing on over 25 years of experience in membrane manufacturing and membrane process technology—from synthesis of raw and auxiliary materials through membrane processing to technical application—FUMATECH has earned particularly high international reputation as a supplier of innovative membranes, the heart of the PEM fuel cell. The company's polymer electrolyte membranes for electrolysis and fuel cell applications, based on PFSA polymer and typically produced in reinforced versions, along with its FAA3 quaternary ammonium-based anion exchange membranes, support water electrolysis and photo-electrolysis research including studies on water-splitting hydrogen and oxygen evolution reactions. FUMATECH's parent company BWT provides complementary water treatment systems specifically designed for hydrogen production, delivering the pure water required for electrolysis processes with the highest hygiene safety and quality standards, positioning the combined FUMATECH-BWT offering as a comprehensive membrane and water treatment solution provider across the growing green hydrogen production and fuel cell technology market.
