According to the invention, the supply and distribution ducts in a fuel-cell stack are arranged such that distribution ducts are arranged in the edge region of the cell surfaces, as a result of stacking and staggering, in such a way that the inlet of the medium to the cell surface along a distribution duct is not carried out in a point-like manner, and that the entire cell surface is uniformly supplied with medium.

[ What is claimed is:] [1.] A fuel cell comprising:a cell surface comprising a cathode, an anode and an electrolyte disposed between the cathode and anode, the cell surface further comprising an underside and a side edge, the side edge having a length,the fuel cell further comprising a coolant distribution duct that extends along at least 50% of the length of the side edge, the coolant distribution duct being in communication with the underside of the cell surface and providing coolant to the underside of the cell surface.the coolant distribution duct being laterally staggered along the side edge with respect to the oxidant and fuel distribution ducts.
