SCoPE – Efficient Welding of Compound Bipolar Plates for PEM Fuel Cells

The ZBT develops the polymer compounds, extrudes films from them, and embosses them into bipolar half-plates. In addition, the institute handles key aspects of material and component characterisation – particularly for compounds, compound films, and embossed bipolar half-plates. Finally, an in-situ stack test is conducted to validate the welded bipolar plates under conditions that closely resemble real-world fuel cell applications. The processes and characterisation methods used in the project build on the ZBT’s research and development achievements.

The SKZ develops and optimises welding processes. First, established methods are examined; then, a suitable joining process is specifically refined. The bipolar plates welded in this manner are comprehensively characterised, particularly with regard to mechanical and chemical stability as well as electrical and thermal conductivity at the joints.

SCoPE addresses a challenge in the manufacture of compound-based bipolar plates that has not yet been sufficiently investigated. Improved joints can help make fuel cells more durable, more efficient, and more cost-effective. This makes the project particularly relevant for small and medium-sized enterprises that cover key parts of the fuel cell technology value chain.

The results are also important in terms of new markets: Fuel cell systems are once again gaining prominence, for example in stationary power and energy supply solutions, decentralised fast-charging infrastructure for electric mobility, data centers, and resilient power supply systems. SCoPE is thus contributing to the further development of robust PEM fuel cell components for future hydrogen applications.

Are you a small or medium-sized enterprise looking to contribute your expertise to the project and benefit from the results early on? Then join us online via Microsoft Teams for the first meeting of the project steering committee on 29 September 2026, from 9:00 a.m. to 11:30 a.m. We are looking for SMEs that would like to actively contribute their practical experience, requirements, and perspectives to the project. Contact Elisabeth now (contact details below) to reserve your spot. All participants will receive the Teams link well in advance of the event.
