Bipolar plates made of high-performance plastics 

In the burgeoning field of hydrogen technology and renewable energy, innovative materials and products often hold the key to significant advancements. Therefore, we offer high-performance, durable and recyclable thermoplastic graphite bipolar plates as a superior alternative to metals and thermosets. Leveraging over 50 years of expertise in high-performance plastics, and in close collaboration with the Centre for Fuel Cell Technology in Duisburg, Germany (ZBT), we have developed advanced compounds for bipolar plates used in fuel cells, redox flow batteries and electrolyzers.

Compared to their metallic and thermoset counterparts, our bipolar plates provide advantages such as corrosion and chemical resistance, design flexibility, and conductivity. As your development partner, we support you from material selection to the final product, offering continuous research and development to enhance the durability, cost-efficiency, and sustainability of industrial applications.

Our compound based thermoplastic bipolar plates offer material specific benefits such as long life, recyclability and process improvements. The use of powder pressing instead of conventional forming processes allows greater design freedom for both the anode and cathode sides, as well as for the design of the cooling channels. This enables the realisation of individual flow field structures and contributes to improved performance of the end application through optimised flow distribution. Working closely with our customers, we develop application-specific bipolar plate designs with short prototype development times and seamless scalability to volume production. From material development to production, we enable flexible, efficient and high performance solutions for industrial applications. All the benefits at a glance:

Our thermoplastic bipolar plates provide a high-quality alternative to conventional metallic and thermoset materials.
