| Abstract: |
Bipolar plates represent the main mechanical structure of the fuel cell stack, which converts the entrained hydrogen through the reaction with oxygen from the air into electrical current, heat and water. The functionality of metallic bipolar plates for automotive applications has already been demonstrated for components manufactured in small series, while the feasibility on the level of large-scale production has not been achieved so far. A particular challenge in this context is the lack of large-scale manufacturing processes. For this reason, the project is concerned with the research and functional verification of new manufacturing processes that enable large-scale production. It is important to link the individual production steps to an economical process chain and to incorporate them into a holistic system concept. |
