1. A separator plate for an electrochemical system, comprising:
at least one through-opening for the passage of a fluid, having a rim that delimits the through-opening, wherein the rim has at least one corner region with a curved course and a first region with a rectilinear first course that adjoins the corner region; and a bead arrangement that extends around the corner region and the first region,
wherein an edge portion is spanned between the bead arrangement and the rim, so that the bead arrangement is situated at a distance from the rim,
wherein, in the corner region, the edge portion has a cutout so that a minimum distance of the bead arrangement from the rim is smaller in the corner region than in the first region.
