Zusammenfassung:	A fuel cell system for a vehicle comprises a fuel cell stack 12 with a first end plate 40 and a second end plate 42. The first end plate 40 and the second end plate 42 each have at least two fuel openings 14/48, 24/56 and at least two oxidant openings 16/50, 28/58. The fuel cell system comprises a control unit 60 configured to open one of the fuel openings 14/48, 24/56 and one of the oxidant openings 16/50, 28/58 to serve as fuel inlet and oxidant inlet respectively, and to open a further one of the fuel openings and of the oxidant openings to serve as fuel outlet and oxidant outlet respectively. The control unit 60 also closes the remaining fuel openings and oxidant openings. The control unit enables different fuel and oxidant openings to be used in various different configurations (figures 3-10), which allows a more even distribution of fuel cell degradation and hence increased lifetime of the fuel cell system. The fuel cell system is preferably used in a vehicle.
