FS-990-PKS - Fuel Cell Membrane

  • Fuel Cell application (H2-PEMFC)
  • Ready for use without pretreatment

Add to compare

The FS-990-PKS is a perfluorinated cation-exchange membrane specifically designed for use in fuel cell applications (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 colorless rigid PET backing layer and is ready for immediate use without any pretreatment. It is reinforced with PK for added durability and is suitable for use in dry form. The membranes performance is supported by its high ion exchange capacity (IEC) and excellent mechanical properties, making it ideal for demanding fuel cell environments.
