A separator plate for an electrochemical system and a bipolar plate comprising two such separator plates for an electrochemical system. An electrochemical system comprising at least two separator plates and/or one bipolar plate. A separator plate comprising: at least one sealing bead for sealing off a region of the separator plate and at least one load relief bead which relieves load on the sealing bead, the load relief bead arranged spaced apart from the sealing bead, and, in a cross-section perpendicular to the course of the load relief bead, at least in a non-compressed state of the separator plate, at least one bead flank of the load relief bead comprises, in at least a first segment along the direction of extension, at least a first, outer portion and a second, inner portion which are at different positive angles to the separator plate plane.
