An electrochemical cell (1) having at least one electrode stack (4), at least one conductor (3), which is connected to at least one electrode stack (4), and a casing (2, 10), which encompasses the electrode stack (4) at least partially. Wherein, at least one conductor (3) protrudes from an opening (9), partially through the cover (2, 10), and the cover (2, 10) has a first layer (5), which is made of an electrically conductive material. Additionally, in the area of the opening (9) is at least one insulating body (6, 8) arranged between said first layer (5) of the cover (2, 10) and the conductor (3).
