Abstract (en)

[origin: WO2020007735A1] In order to provide an electrochemical device, comprising a stack of multiple electrochemical units which follow one another along a stacking direction and each comprise an electrochemically active membrane-electrode arrangement, a bipolar plate and a sealing system, at least one medium channel, which extends along the stacking direction through a number of the electrochemical units, and at least one flow zone, through which a medium from the medium channel can flow transversely to the stacking direction from the medium channel to another medium channel, wherein the sealing system comprises a flow-zone sealing arrangement, which extends around at least one flow zone, and at least one medium-channel sealing arrangement, which extends around a medium channel, in which electrochemical device the sealing system has a high mechanical stability and can be precisely positioned during the assembly of the electrochemical device, it is proposed that the flow-zone sealing arrangement is fixed on the membrane-electrode arrangement and the at least one medium-channel sealing arrangement is fixed on the bipolar plate.
