Description Vendor

The F-1850 is a fluorinated cation-exchange membrane designed for fuel cell applications (DMFC), redox-flow batteries, and other electrochemical processes. It is a colorless, transparent foil with a thickness of 45–50 μm and is delivered on a white rigid PET backing foil. The membrane has low resistance, high permeation-blocking capability, and high stability in acidic environments. It is ready for use without any pretreatment and offers excellent conductivity, selectivity, and mechanical properties, making it suitable for demanding electrochemical applications. The membrane is characterized by its high stability in acidic environments, low area resistance, and high selectivity, which are critical for efficient and reliable electrochemical processes.

Use Cases

  • Fuel Cell application (DMFC)
  • Redox-Flow Batteries
  • Other electrochemical processes

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.
