Abstract: A separator plate for an electrochemical system, an electrolyzer, a bipolar plate comprising such a separator plate, an electrolyzer comprising such a separator plate, and to tooling for producing such a separator plate. The separator plate comprising a flow area having a plurality of integrally formed support structures. An outer contour of the support structures in each case comprises: a first circular arc-shaped portion and a second circular arc-shaped portion, wherein a circular arc center point of the first circular arc-shaped portion and a circular arc center point of the second circular arc-shaped portion are arranged at a distance from each other on a longitudinal axis of the respective sup-port structure, and a joining portion which joins together the first circular arc-shaped portion and the second circular arc-shaped portion, wherein a width of the joining portion is smaller than a diameter of the first and/or second circular arc-shaped portion.

Abstract: A separator plate is disclosed for an electrochemical system. The plate comprises a multitude of mutually parallel and adjacent channels that are designed to guide a fluid at least along a region of the separator plate, wherein the channels each have a depth, a longitudinal extent, a channel base and two sidewalls, wherein the following conditions apply to at least one of the channels: the depth of the channel in a first region of the channel is essentially constant along the longitudinal extent, the channel base in the first region of the channel is essentially flat and the depth of the channel in a transition region of the channel that adjoins the first region decreases along the longitudinal extent, as a result of which a channel base continuation in the transition region is curved.
