Zusammenfassung:Bipolar plate has plate elements (2a) having a hollow chamber (3) and identical channel structures (4a, 4b). The plate elements have a first recess (5') open to the hollow chamber and a second recess (5'') closed to the hollow chamber. The first recess is aligned with the second recess to form a coolant passage opening through the bipolar plate. Independent claims are also included for: (a) Plate elements used in the production of the bipolar plate; and (b) Process for the production of a bipolar plate.
