Overview
Hydrogen fuel cells provide a clean and efficient way to store and transport energy for use in homes, businesses, and vehicles.
VERSIV multi-material composites work as industry-leading protection and barrier solutions when used as cells, seals, and separators within hydrogen fuel cells and electrolyzers. Our films and fabrics increase membrane electrode assembly efficiency and help manufacturers achieve reduced stack height, high-speed decal productivity, and thinner, more homogenous catalyst layers.
VERSIV films are ideal for customized fuel cell and electrolyser solutions as it can be further processed by various techniques such as stretching, laminating, or surface treating to enhance its properties for specific applications.
VERSIV monolayer films enhance the performance of fuel cells, irrespective of the most stressful and challenging conditions, including working at high pressures and temperatures of up to 300˚C (572˚F) and in harsh chemical environments. By helping to maximize fuel cell performance and longevity, our solutions are contributing to their wider usage, both as components and as process aids.
Benefits of Versiv films in hydrogen fuel cell and electrolyzer infrastructure
High chemical resistance: 
PTFE-coated films are highly resistant to chemicals, making them ideal for use in the harsh chemical environment of hydrogen fuel cells and electrolysers. It can withstand exposure to aggressive chemicals such as strong acids and bases, which are commonly used in the manufacturing of fuel cells and electrolysers.
Low permeability to gases:
Our films have extremely low permeability to gases, including hydrogen, which is a key component in fuel cells and electrolysers. This property ensures that hydrogen gas is contained within the cell and does not leak out, which is essential for the safe and efficient operation of the application.
Excellent electrical insulation: 
Versiv films are an excellent electrical insulator, which is important in hydrogen applications where electrical current must be conducted through the fuel cell or electrolyser without shorting out. These fluoropolymer-based films can be used as separators between the cell layers, preventing electrical contact between the anode and cathode.
High-temperature resistance:
Our films have excellent high-temperature resistance, which is important in such applications where high temperatures are generated during operation. PTFE-based films can withstand temperatures up to 260°C (500°F) without degradation, ensuring long-term performance and reliability.
Applications within fuel cells
Gaskets
Gaskets made from Versiv films can be used to protect graphite Bi-polar plates in fuel cells. The films help to increase the durability and stability of the Bi-polar plate by protecting it from corrosion and other forms of degradation. This can lead to longer lasting and more efficient fuel cells.
Decal transfer process aid
Our films can be used as a substrate/carrier during the Decal Transfer Method. Our materials are ideal for the process as they provide smooth and homogenous surfaces and very tight thickness control. It means the coating process can be optimized during the DTM, resulting in very thin catalyst layers, improving the efficiency of the MEA and the overall stack. The used surface energies allow both wettability and release.
