Abstract (en)
[origin: WO2020007731A1] The invention relates to a method for producing a sealing element on a gas diffusion layer of an electrochemical unit, wherein the method comprises the following: - arranging an injection molding tool on the gas diffusion layer; - introducing injection molding material into a cavity of the injection molding tool, in which damage to the gas diffusion layer is prevented and a sealing element having a mechanically stable connecting region is produced. It is proposed that the injection molding tool comprises at least one deformation limiting element which limits or prevents a deformation of the gas diffusion layer during the introduction of the injection molding material into the cavity.
