  • Supports prototype and production tooling
  • Scales toward series manufacturing
Cell Impact AB Cell Impact AB is a Swedish manufacturer of customized bipolar flow plates for hydrogen fuel cells and electrolyzers, based in Karlskoga, Sweden, positioning itself as the premier bipolar flow plate manufacturer globally with over 50 completed customer projects. The company's proprietary Cell Impact Forming technology is a high-velocity forming process ideally suited for shaping thin metal coil with high precision in a single stroke, softening the material as it forms (unlike conventional progressive pressing, which stretches and can crack the metal) to achieve superior flow-channel pattern quality that directly affects fuel cell energy efficiency. Cell Impact offers services from plate design optimization through prototyping and high-volume production, including leak testing, cleaning, and advanced geometric measurement, and has developed a laser-welding process to join anode and cathode plates into low-cost, high-quality bipolar plates. The company is actively expanding its forming technology for electrolyzer flow plate manufacturing, working with leading electrolyzer producers to adapt the process for thicker materials and different electrolyzer-specific designs.
