The invention relates to a separating plate (28) comprising: a half-sheet (3, 4) having an active zone (2); a frame means (11) surrounding the active region (2); and a sealing device (15, 15 ') assigned to the frame device (11) and comprising a seal (16, 16') extending in a wave shape in a top view of a plane spanned by the separating plate (28). A three-dimensional support structure (29) is formed in the half-sheet (3, 4) in the region of the sealing device (15, 15 '), the support structure (29) being formed so as to protrude from the plane spanned by the separator plate (28). The invention also relates to a bipolar plate (1, 1'), a method for producing a sealing device (15, 15 ') on a separator plate (28) or a bipolar plate (1, 1'), and an electrochemical cell (40).
