Abstract
Systems and methods for separator plates, bipolar plates, stacks of plates, and electrochemical systems, comprising at least one through-opening for the passage of a fluid and a rim that delimits the through-opening. The rim having a curved course and a rectilinear course that adjoins the curved course. A bead arrangement extends around the curved course and the rectilinear course. An edge portion spans the bead arrangement and the rim, so that the bead arrangement is situated at a distance from the rim. A cutout formed in the curved course, so that a minimum distance of the bead arrangement from the rim is smaller in the curved course than in the rectilinear course.
Claims19
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.
