Abstract
The invention relates to a fuel cell system (1) which is characterized in that a fuel cell stack (2) comprised of a plurality of intermediate plates is enclosed between two end plates (3) to compress the intermediate plates. At least one end plate (3) has an end plate base (4) and a contact surface plate (5) linked therewith to electrically contact the fuel cell stack. The end plate base (4) is furthermore provided with channel structures (6) designed for a cooling circuit for cooling the fuel cell stack. The end plate is deformed in such a manner that it is capable of applying an even compression to the fuel cell stack and to balance the setting behaviour of the stack and of the end plate.
