Extruded graphite bipolar plates
Our extruded graphite bipolar plates also exhibit high corrosion resistance to various electrolytes. They impress with good mechanical strength without brittle fracture as well as very good liquid tightness. Another advantage of the thermoplastic material is that the flexible bipolar plate can be welded directly to the frame of the battery stack. This replaces conventional sealing solutions and ensures a very compact design. By optimizing our formulations, we can precisely match the electrical, mechanical and thermal properties. The thermoplastic-bonded high-performance material is transferred into a continuously produced film. This makes it possible to produce bipolar plates in large formats (> 1000 mm length and 380 mm width). The film can be given additional features by surface treatment and finishing.
