TERMINAL BIPOLAR PLATE FOR AN ELECTROCHEMICAL SYSTEM, PLATE ASSEMBLY, AND ELECTROCHEMICAL SYSTEM

A plate assembly for an electrochemical system, comprising an end plate, a first separator plate which adjoins the end plate and which has a plate plane, a second separator plate which adjoins the first separator plate, the second separator plate having at least one media-guiding second through-opening, wherein an orthogonal projection of the second through-opening onto the first separator plate perpendicular to the plate plane defines a projection area, wherein the first separator plate has in the region of the projection area no through-opening or a first through-opening, the area of which is less than 20% of the area of the second through-opening.
