Abstract: A fuel cell stack includes a plurality of bipolar plates wherein each bipolar plate has at least an anode plate and a cathode plate, and a plurality of membrane electrode assemblies being sandwiched by the bipolar plates, wherein each membrane electrode assembly has at least an anode and a cathode which are separated by a membrane, wherein the bipolar plates sandwich the membrane electrode assembly in such a way that the anode of the membrane electrode assembly faces the anode plate of a first bipolar plate and the cathode of the same membrane electrode assembly faces the cathode plate of a second bipolar plate; and wherein a cell pitch of the fuel cell stack is defined by a distance of two adjacent membrane electrode assemblies, wherein at borders of the bipolar plates of the fuel cell stack, an overall distance between the anode plate of the first bipolar plate and the cathode plate of the second bipolar plate, which is measured over the sandwiched membrane electrode assembly, is equal to the cell pitch of the fuel cell stack.
