description The invention relates to a bipolar plate (7) for an electrochemical cell (1), said bipolar plate comprising at least one first monopolar plate (13) having a first bead (15) and a second monopolar plate (17) having a second bead (19), the first bead (15) and the second bead (19) being arranged opposite one another and forming a channel (21), the first bead (15) and the second bead (19) each comprising a central base surface (23) and at least two inclined surfaces (24), and the first bead (15) and/or the second bead (19) comprising at least one outer base surface (25). At least one opening element (111) for the passage of at least one medium (29) between one of the at least two inclined surfaces (24) and the at least one outer base surface (25) is located on the first bead (15) and/or the second bead (19), said at least one opening element (111) comprising a lateral surface (121), a first open side surface (113), a second open side surface (115), and a top surface (140) having an opening (27), said first open side surface (113) being located in the at least one outer base surface (25), and said second open side surface (115) being located in one of the at least two inclined surfaces (24). The invention also relates to a method for manufacturing the bipolar plate (7), to an arrangement (69) of electrochemical cells (1), and to a method for operating said arrangement (69) of electrochemical cells (1).
