Solutions for Hydrogen Fuel Cell Stack and Electrolysers

Versiv products are primarily used as processing aids for catalyst coating and lamination of Membrane Electrode Assemblies (MEA) in fuel cells. Versiv materials enable the production of thinner catalyst layers, which can increase cell efficiency. They also offer improved productivity due to higher process speeds and consistent production processes.

When selecting materials for Proton Exchange Membrane Fuel Cell (PEMFC) gaskets and sub-gaskets, key considerations include chemical stability against acidic and oxidative environments, temperature resistance up to 185°C, and the ability to provide effective sealing through good compressibility and gas tightness. Additionally, materials must ensure electrical insulation, maintain dimensional stability, and exhibit low compression set and minimal swelling over time. 

Sealing solutions are vital for the efficiency and lifespan of Proton Exchange Membrane Fuel Cell (PEMFC) stacks as they prevent gas leakage and contamination, enhance durability against harsh conditions, and enable effective thermal management. By ensuring optimal operating conditions and allowing for higher pressure operation, high-quality seals contribute significantly to improved performance and longevity of fuel cells.

Versiv materials serve as precise, smooth, and thickness-controlled decal substrates for producing catalytic layers via the decal transfer method in catalyst coated membrane production. They also function as release liners with excellent release properties, ensuring the substrate can be removed without damaging the costly catalytic layer. Versiv materials address issues such as thermal hysteresis, non-perfect wetting, and non-perfect transfer in production of catalyst layers for fuel cells.

Key features include low thickness tolerance, excellent non-stick surface, superior chemical resistance, smooth surface, low shrinkage/hysteresis, excellent heat transfer, and high temperature resistance up to 260°C / 500°F.
