    • As processing aids for catalyst coating and lamination of Catalyst Coated Membranes (CCMs), present inside Membrane Electrode Assemblies (MEA).

    Main Benefits of Versiv Materials for Hydrogen Fuel Cells and Electrolysers:

    High chemical resistance:

    Versiv PTFE films and coated fabrics are highly resistant to chemicals – such as strong acids and bases – making them ideal for use in the harsh chemical environment of hydrogen fuel cells and electrolysers.

    Excellent electrical insulation:

    Versiv PTFE films are excellent electrical insulators. These fluoropolymer-based materials serve as separators between cell layers, preventing electrical contact between the anode and cathode.

    High-temperature resistance:

    Versiv PTFE films and coated fabrics have excellent high-temperature resistance. They can withstand temperatures up to 260°C (500°F) without degradation, ensuring long-term performance and reliability.

    Low permeability to gases:

    Versiv films have extremely low permeability to gases, including hydrogen, which is the key component in fuel cells and electrolysers. This property ensures that hydrogen gas is contained within the cell and does not leak out.

    Stacking Materials inside Fuel Cells and Electrolysers

    Versiv composites are used as frames and gaskets within the fuel cell system. They provide modularity to the system, protecting the protect graphite Bi-polar plates and ensuring the energy efficiency of the fuel stacks.

    Problems solved:

    • Early leakage
    • Inhomogeneous pressure distribution

    Applications:

    • Membrane Electrode Assemblies (MEA) Systems:
      • Proton-Exchange Membrane (PEM) electrolysers & fuel cell systems
      • Alkaline electrolysers & fuel cell systems
    • Phosphoric Acid Fuel Cells (PAFC)

    Decal substrates for fuel cell Catalyst Layer production

    Versiv materials work as a very precise, smooth and thickness-controlled decal substrate in the production of catalytic layers via decal transfer method. In a second step this substrate becomes a release liner with excellent release properties ensuring that the substrate can be removed without damaging the very costly catalytic layer.

    Problems solved:

    • Thermal hysteresis
    • Non-perfect wetting
    • Non-perfect transfer

    Applications:

    • Processing aids for catalyst coating and lamination of Membrane Electrode Assemblies (MEA)

    PTFE release for surface quality in wind energy blade manufacture

    The manufacturing process using Versiv components involves integrating PTFE-coated fabrics and tapes to create effective release liners. These materials are designed to withstand the rigors of production while providing superior performance in preventing adhesion and ensuring high-quality surface finishes.

    Versiv materials cover the mould.

    The enormous forces and temperatures during composite moulding processes put high stress on moulds, parts and materials. Versiv CLPSA 4 is a laminated PTFE-coated fabric, design to withstand this challenging environment.

    Versiv CLPSA 4 S is a laminated PTFE adhesive tape system engineered to withstand the high forces and temperatures of composite moulding. A reusable and durable alternative to waxes and sprays, it helps produce defect-free parts with improved surface quality and less need for post-processing. Its silicone pressure-sensitive adhesive secures the tape in place while protecting moulds and tooling and helping extend their operational life.
