Abstract: A fuel cell stack is provided, which comprises at least a plurality of unit fuel cells, wherein each unit fuel cell comprises a bipolar plate and a membrane electrode assembly, which are stacked such that two bipolar plates sandwich a multi-layer membrane electrode assembly in a stacking direction. Each bipolar plate and/or membrane electrode assembly comprises at least one reactant inlet manifold and at least one reactant outlet manifold, wherein the manifolds form respective tubelike channel inlets and channel outlets. The channel inlets and channel outlets extend through the fuel cell stack for providing a reactant stream to and from the fuel cell stack, wherein the plurality of unit fuel cells is sandwiched by a cover plate and a feeding plate. The cover plate is configured to cover the fuel cell stack, wherein at least one turbulence element is arranged in the stream of reactant.
