Unknown

The electrochemical system, comprising:

• an end plate;
• a stack cover plate adjacent to the end plate;
• and
• at least one metallic electrical conductor;
• wherein the stack cover plate has an electrically conductive contacting plate adjacent to the end plate and an electrically conductive separator plate half facing away from the end plate, wherein the contacting plate and the separator plate half are connected to each other electrically and media-tight;
• wherein the metallic electrical conductor extends to an outside of the electrochemical system;
• and
• wherein the metallic electrical conductor and the contacting plate are in one piece or the metallic electrical conductor contacts the contacting plate directly;
• wherein the contacting plate and the separator plate half are bonded to each other.
