Fuel cell stack comprising at least two fuel cells which are separated by a separator plate. It is proposed for the cathodic gas-distribution element adjoining the separator plate to be attached to the said separator plate by welding, thus ensuring a good mechanical connection and an optimum passage of current. To minimize corrosion problems, the steel separator plate is alloyed with 4-11 % by weight aluminium and more particularly approximately 6 % by weight aluminium. Moreover, the separator plate is made from a steel which is preferably alloyed with 8-25 % by weight chromium.
