The media duct is connected or can be connected to the fuel cell stack to conduct a medium into or out of the media channels of the unit cells of the fuel cell stack substantially laterally to the stacking direction, and comprises duct flanges that are connected at least indirectly to each other and can be connected or are connected to the fuel cell stack. The duct flanges of the media duct are inserted into flange receptacles of the fuel cell stack running substantially parallel to the stacking direction.
