KIT FOR A FUEL CELL STACK AND METHOD FOR PRODUCING A FUEL CELL STACK

A kit for a fuel cell stack comprises a first plurality of unit cells of the same design, which can be stacked on top of each other in a stacking direction and which each have one or more media channels and a membrane electrode assembly, the membrane electrode assembly comprising a cathode, an anode, and a membrane arranged between the cathode and the anode, a first media guide, which can be laterally connected to the first plurality of unit cells and runs parallel to the stacking direction, having a first usable flow cross section, in order to guide a medium into or out from the media channels of the unit cells of the first plurality of unit cells substantially laterally with respect to the stacking direction, a second plurality of unit cells of the same design, and a second media guide, which can be connected laterally to the two pluralities of unit cells stacked on top of one another and running parallel to the stacking direction, having a second usable flow cross section, different from the first usable flow cross section, in order to guide a medium into or out from the media channels of the unit cells of the two pluralities of unit cells substantially laterally to the stacking direction. A method for production of a fuel cell stack of a fuel cell device is also provided.
