A gasket has sealing layer(s) with beads which are assigned to passage opening(s), and stopper layer(s) with a stopper which limits the resilience of the bead(s). The stopper is composed of a plurality of directly successive ridge-shaped elevations and groove-shaped depressions, both being trapezoidal in cross section and both being formed in on both sides of the stopper layer, with setting angles of the trapezium flanks. The trapezoidal elevations of the one side are situated opposite the trapezoidal depressions of the other side. A cross section (Q) which is delimited by opposing trapezium flanks which are adjacent to one another is the same or greater than a cross section (Q) which is delimited between the opposing depressions of the two sides.

The invention deals with an electrochemical system for compressing gases and/or for producing gases by electrolysis, consisting of an electrochemical compressor stack () having layering of several electrochemical cells, which are separated from one another in each case by bipolar plates ('), wherein the bipolar plates have openings for media supply and media discharge () for the electrochemical cells and the electrochemical cell stack can be placed under mechanical compressive strain in direction () of the layering. The bead arrangements (&#x2032;) are resilient and are provided at least in some regions to seal the openings () and/or an electrochemically active region () of the electrochemical cells.
