An electrochemical cell has an energy unit (10) which has an electrode stack, at least one main lead (12, 14) which is connected to the electrode stack, and a casing (18) which at least partially surrounds the electrode stack; at least one frame element (16) which at least partially accommodates the energy unit (10); and at least one pressure-relief apparatus (32, 46). The casing (18) has a plurality of edge sections at the peripheral narrow sides of the electrochemical cell, wherein the at least one main lead (12, 14) extends at least partially out of the casing (18) in a first edge section and this first edge section of the casing (18) has a substantially fluid-tight first sealing seam (20, 22). In addition, the at least one frame element (16) has at least one first supporting web (34, 36) in the region of the first edge section of the casing (18), said supporting web being at a distance of a maximum of approximately 1 mm from the first sealing seam (20, 22) of the casing (18) and thereby preventing or at least making it difficult for this first sealing seam (20, 22) to tear open in the region of the at least one main lead (12, 14) in the event of an increase in the pressure and/or temperature in the interior of the cells.
