Description Vendor

The FS-710-RFS is a perfluorinated cation-exchange membrane specifically designed for use in hydrogen fuel cells (H2-PEMFC). It is characterized by its low electrical resistance, high mechanical stability, minimal dimensional swelling, and exceptional stability in acidic environments. The membrane is delivered as a transparent foil on a multilayer PET backing, making it ready for immediate use without the need for pretreatment. It is suitable for use in dry form and requires careful handling to avoid damage, such as punctures, creases, or scratches, which could lead to leaks. The membrane is reinforced and stabilized, with a thickness of 9-13 μm, and offers high ion exchange capacity (IEC) and excellent mechanical properties, including a Youngs modulus of over 300 MPa and tensile strength exceeding 40 MPa. It is ideal for applications requiring high performance and durability in fuel cell systems.

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.
