H2Giga - StacIE: Stack Scale-Up: Industrialization PEM Electrolysis

StacIE aims to scale up the stack production on the level of cell components by development of industrial processes, improvement of profitability of cell design by reducing complexity and optimizing manufacturing technique of the porous transport layer (PTL) and bipolar plate (BPP). For PTL and BPP alternative materials and substrate coating methods are identified and developed further. Additionally, an increase in performance and lifetime is aimed for.
Fabrication techniques for a direct coating of the catalyst layer onto the porous transport layer is developed and investigated, overcoming the challenge to optimize the structure of the PTL to the catalyst layer. Also, accelerated stress tests are developed and the degradation mechanisms unraveled. Thorough structural elucidation completes the picture.
