Abstract
In order to create an electrochemical device, comprising a plurality of electrochemical units, which succeed one another along a stack direction, wherein each electrochemical unit comprises a bipolar plate and an electrically insulating seal, and a clamping device for clamping the electrochemical units along the stack direction, in which electrochemical device the risk of a short circuit between adjacent bipolar plates is reduced without the expenditure for the production of the electrochemical device being excessively increased, it is proposed that at least one seal of at least one electrochemical unit in the pressed state protrudes laterally beyond a contour of the bipolar plate of the electrochemical unit in a direction of protrusion directed perpendicularly to the stack direction.
