Abstract: The present disclosure relates to a separator plate or cell frame for an electrochemical device, in particular for an electrolyzer or a fuel cell, having a first metallic layer with a first side and a second side opposite the first side, wherein the separator plate or the cell frame has at least one first through-opening for the supply of reaction medium and at least one second through-opening for the discharge of reaction medium, characterized in that the metallic layer has at least one first recess on the first side, which completely circumferentially encloses an inner space of the first recess, the inner space being completely filled with a first non-compressible material.

Abstract: The present disclosure relates to a separator plate for an electrolyzer having a first layer with at least one through-opening for a fluid and an active region with a set of flow channels for the fluid. A first elastomeric molding with at least one sealing lip is arranged on a first side of the first layer at least partially surrounding the through-opening. The sealing lip extends at least partially along a peripheral edge of the through-opening. A second elastomeric molding surrounding the through-opening is arranged on a second side of the first layer, with a set of ribs which form grooves between them as flow channels for the fluid. For each flow channel, one longitudinal end is open to the through-opening and the other is open to the active region. The first layer has a cranked region at a distance from the through-opening and at least partially around the through-opening.

Abstract: A seal, in particular a gasket, for sealing with at least one sealing layer a gap in a housing that extends around an inner chamber of the housing. In particular, a frame seal which seals between a lower part and an upper part of the housing, for example a motor vehicle battery housing or a motor vehicle battery box housing.

Abstract: The present disclosure relates to a seal for sealing an inner chamber of a housing from an exterior of the housing, comprising at least one sealing layer that has: at least two rigid sealing layer portions having a respective support element, wherein the rigid sealing layer portions are interconnected by a flexible sealing layer portion, which consists of or comprises at least in part an elastomer; and at least one sealing contour, which extends continuously over the different sealing layer portions, wherein the support elements each comprise, in an end region adjoining the flexible sealing layer portion, at least one through-opening, through which the elastomer of the flexible sealing layer portion extends, and the end region of each support element is coined in at least one first end-side coining region and is enclosed by the elastomer in the first end-side coining region at least in some regions.
