World's largest bipolar plate

Product description

Fraunhofer UMSICHT develops thermally and electrically conductive plastic compounds that can be processed into thermoplastic-based bipolar plates with different fill levels and thicknesses, depending on the customer's needs. These can be used in a variety of technical ways and can be optimized for specific applications and needs: in electrochemical storage systems (batteries), in energy converters (fuel cells), in chemical-resistant heat exchangers or as resistance heating elements. The customer receives a tailor-made product, which can be produced inexpensively via a roll-to-roll process.

Researchers at Fraunhofer UMSICHT have developed a 3.2 m² bipolar plate, which in its size is so far unique and is a key technology for e.g. large redox flow batteries as stationary energy Storage. Other decisive advantages of the new bipolar plate are the low minimum thickness (400-500 µm), the accompanying good conductivity, their flexibility and the cost-efficient Role-to-roll production method.
