Abstract

The present invention relates to a sealing device (100) for sealing a membrane electrode assembly (210) of an electrolyser cell (200) against one or more bipolar plates (220) of the electrolyser cell (200). The sealing device (100) comprises a seal (110), which extends in a width direction (101) between two opposite seal surface sides (111, 112) for sealing against respective seal counter-surfaces (211, 221) of the electrolyser cell (200) and further comprises a seal lateral side (113), which is provided laterally of the seal surface sides (111, 112). The sealing device (100) comprises further at least one limiter (120) for limiting a compression of the seal (110) in the width direction (101) by engaging two opposite limiter surface sides (121, 122) of the limiter (120) with the seal counter-surfaces (211, 221). The limiter (120) comprises further a limiter lateral side (123), which is provided laterally of the limiter surface sides (121, 122). At least a part of the limiter lateral side (123) is mechanically connected to at least a part of the seal lateral side (113).
