Abstract:
The invention relates to: a bipolar plate (1); and an electrochemical cell (12) comprising a plurality of such bipolar plates (1, 1'). The bipolar plate (1) comprises a first half-plate (1a) and a second half-plate (1b) which are fixedly connected to one another, wherein: the bipolar plate (1) has a plurality of fluid passage openings (2) comprising fluid inlet openings (2a, 2c, 2e) and fluid outlet openings (2b, 2d, 2f); and a first distributor field (3) for distributing a fluid, an active field (4), and a second distributor field (5) for distributing the fluid are located on both sides of the bipolar plate (1). There is also at least one seal (6, 6') on each side of the bipolar plate (1), wherein, in at least one transition region (7) between a fluid passage opening (2) and an adjacent distributor field (3, 5), the seals (6, 6') are positioned congruently one above the other as seen perpendicularly to a plane spanned by the bipolar plate (1) and are reinforced by embossed structures (9a, 9b).
