Metallic Bipolar Plates for Electrolyzers

Dana Limited

Fully integrated sealing added via injection molding process
Conductive coating (PVD) with high electrical conductivity
Low contact resistance and long-term durability
High-volume production capability via integrated forming and welding
Reduced complexity enabling seamless assembly

Dana has innovated a game-changing metallic bipolar plate technology that eliminates the traditional cost, complexity, and performance barriers, enabling broader commercialization. These plates feature proprietary, fully integrated sealing, conductive coating, and a fully integrated, high-speed forming and laser welding process. They are designed for high-volume production, high pressure levels, and increased power density, with industry-leading performance and cost. The plates have a complex pattern of channels and ports, and are part of an electrolyzer stack assembly. The proprietary, fully integrated sealing is added by injection molding process to lower cost and offers outstanding performance under extreme conditions. The conductive coating uses a PVD solution, providing high electrical conductivity, low contact resistance, and long-term durability. The fully integrated, high-speed forming and laser welding process enables high-volume production efficiency at lower cost and increases power density.
