SEALING ARRANGEMENT, BIPOLAR PLATE AND ARRANGEMENT FOR AN ELECTROCHEMICAL SYSTEM AND ELECTROCHEMICAL SYSTEM

Abstract: the present disclosure relates to a sealing arrangement, a bipolar plate, an arrangement for an electrochemical system, and an electrochemical system. the sealing arrangement comprises a frame-shaped layer, a first elastomeric sealing element and/or a second elastomeric sealing element, and an elastomeric fluid guide structure. the frame-shaped layer has a cut-out extending over an electrochemically active region, and a through-opening for passing a fluid. the first sealing element lies against an inner edge of the through-opening and projects laterally into the through-opening in order to seal the through-opening. the second elastomeric sealing element lies against an inner edge of the cut-out and projects laterally into the cut-out in order to seal the cut-out. the elastomeric fluid guide structure has a plurality of fluid passages for passing fluid from the through opening to the cut-out or vice versa.
