Abstract (en)
[origin: WO2022083899A1] The invention relates to a method for producing a functionally structured assembly for a fuel cell (1), comprising the following steps: applying at least one electrode (4, 6) comprising catalyst particles (13) to a substrate layer in a coating step, and introducing a depth structure (16) into an electrode surface facing away from the substrate layer in a beam step by means of laser interference structuring. The invention also relates to a membrane electrode assembly.
