The invention relates to a fuel cell stack having at least two segments of individual fuel cells arranged in parallel in terms of fluid, said segments being arranged in series relative to one another in terms of fluid. It is provided that the fuel cell stack is set up to vary the number of individual fuel cells in at least one segment.

Variably segmented fuel cell stack, and fuel cell system and vehicle comprising same

The invention concerns a fuel cell (), comprising a stack () of alternating bipolar plates () and membrane electrode assemblies () as well as flow channels () that are designed between a bipolar plate () and a membrane electrode assembly () and flow channels () that are designed within a bipolar plate () as well as a motor vehicle with such a fuel cell. Provision is made that a surface () of at least a part of the flow channels () that is overflowable by a fluid has, regarding its direction of extension at least in part a hydrophobic segment () and a hydrophilic segment () with regard to a cross-section of the flow channel ().
