Document Type and Number:
WIPO Patent Application WO/2023/118125
Kind Code:
A8
Abstract:
In order to provide a method for producing a bipolar plate layer for a bipolar plate of an electrochemical unit of an electrochemical device, with the method steps of providing a starting material for the bipolar plate layer and shaping the starting material in such a way that an edge piece bordering the flow field of the bipolar plate layer is formed, which method can be easily and reliably carried out even with large quantities of bipolar plate layers to be produced, according to the invention, the method comprises the following steps: cutting out gas through-openings from an edge piece section of the starting material, wherein, once the gas through-openings are cut out, the edge piece section is shaped such that the edge piece is formed from the edge piece section.
