Electrochemical system unit with sealing elements

An electrochemical system unit comprising a plurality of electrochemical cells (30) arranged next to one another in layer-like fashion, each of the electrochemical cells having an anode plate (32), a cathode plate (36) and a sealing element (38), wherein the sealing element (38) is configured to seal a space between the anode plate (32) and the cathode plate (36);

• and at least two electrochemical cells (30) of the electrochemical system unit have different manufactured types (10a, 10b, 10c, 10b, 38a, 38b) of the sealing elements (38),
• wherein the different manufactured types (10a, 10b, 10c, 10d, 38a, 38b) of the sealing elements (38) are applied to an electrode plate (32, 36) of the electrochemical cells (30) by an injection molding method,
• wherein the different manufactured types (10a, 10b, 10c, 10d, 38a, 38b) of the sealing elements (38) have manufacturing-related irregularities (12, 40a, 40b) in different spatial regions of the sealing element (38) such that the manufacturing-related irregularities (12, 40a, 40b) are not aligned with one another in any section taken through the different sealing elements in a stacked direction of the sealing elements,
• wherein the manufacturing-related irregularities (12, 40a, 40b) are caused by at least two different positions of an injection point (12) of the injection molding method in relation to a form of the sealing element (38).
