The present disclosure relates to a bipolar plate for an electrochemical system and an electrochemical system comprising a stacked plurality of such bipolar plates as well as a method for the production of such bipolar plates. The electrochemical system may be a fuel cell system, an electrochemical compressor, an electrolyzer, or a redox flow battery. The bipolar plate comprises a first separator plate and a second separator plate connected to each other which delimit an inner space. Each separator plate has an inner side with an inner coating and an outer side with an outer coating. Fluid guide structures are molded into an electrochemically active region of each separator plate by shaping of the respective separator plate. The inner coating extends along the electrochemically active region and has defects at least in some regions. The outer coating extends along the electrochemically active region and has a substantially uniform surface texture.
A bipolar plate, comprising a first separator plate and a second separator plate, which are connected to each other and delimit an inner space of the bipolar plate,
A method of manufacturing a bipolar plate comprising at least the following steps:
