Beschreibung
Zusammenfassung:	A fuel cell device with a fuel tank which has a fuel supply line which is branched into fuel portion supply lines, having a plurality of fuel cell stacks which stacks each have, on the anode inlet side, a fuel connection which is respectively fluidically connected to one of the fuel portion supply lines. Exclusively one of the fuel cell stacks is connected on the anode outlet side to a fuel recirculation line. The flow guidance of the fuel recirculation line is selected in such a way that the fuel can be returned exclusively into the fuel cell stack connected to the fuel recirculation line. Furthermore, a method for operating the fuel cell device is provided.
