HYTECHBASIS 4 WIVA aims to reach higher level of industrialization by developing next generation PEM fuel cell as well as PEM electrolysis technology. By applying advanced catalyst coated membrane technology and the usage of sophisticated technology in bipolar plate manufacturing, HYTECHBASIS 4 WIVA fundamentally improves state-of-the-art electrolysis technology. Moreover, a generic PEM fuel cell system platform based on next generation low-cost metal bipolar plates stack architecture and highly function integrated peripheral components paves the way for a broader range of marketable applications. Both technologies, electrolysis and the fuel cell, benefit from a newly considered holistic approach applied in HYTECHBASIS 4 WIVA.
