A fuel cell stack includes a plurality of stacked fuel cell units and at least one stack end element that are clamped a clamping device. The clamped fuel cell units are surrounded by a housing. A circumferential seal, in particular a lip seal, which has recesses for accommodating the clamping device is situated between the housing and the at least one stack end element. The clamping device is electrically insulated at least in the area of the recesses.

Fuel cell stack

The inventive end plate comprises pressure shield () and a supporting plate (), whereby the forces, which serve to compress the stack () of fuel cells () and which are introduced via the force introduction locations (), are introduced into the stack in the form of a compressive load in a defined and uniform manner.
