JW Froehlich and the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) have crated a modular and scalable test system for fuel cell stacks. The joint project resulted in a prototype, which is being operated by ZSW fuel cell experts in Ulm. The findings and experience from the project are directly implemented in our work at JW Froehlich, with a focus on optimizing test systems and meeting the requirements of large-scale series production.

The prototype is scalable with respect to output, power class and measuring channels. The modular concept permits various design levels up to a fully automated EOL test stand. The system is loaded manually, by trolley, transport system or robot; the test parts are adapted either manually, semi-automatically or fully automatically. The retractable media modules (cathode, anode, electrical modules, coolant) can be easily maintained or altered on the stand.

The federal state of Baden-Württemberg has added this innovation project to its “ZPH2 – Zukunftsprogramm Wasserstoff BW” funding programme. Through this initiative, Baden-Württemberg is contributing to the establishment of a sustainable hydrogen economy in south-west Germany.

The innovation project is funded by the Ministry of the Environment, Climate Protection and the Energy Sector Baden-Württemberg and supervised by the Project Management Agency Karlsruhe (PTKA).
