Climate-friendly fuel cell systems, which are set to power machines such as vehicles in the future, are still rare and expensive these days. There are several reasons for this, including the complex and costly process used to produce bipolar plates — a key component in electrolyzers and fuel cells, which are needed for many hydrogen systems. The Fraunhofer Institute for Machine Tools and Forming Technology IWU has now taken a major step toward lower costs and mass production of bipolar plates by introducing an innovative system for roll embossing: BPPflexRoll. The Fraunhofer researchers will be pre-senting one component of the system at the joint Fraunhofer booth in Hall 2, Booth B24, at Hannover Messe 2024 from April 22 to 26.
