Claim 14:
15. A fuel cell arrangement, comprising:
at least one fuel cell configured to provide an electrical fuel cell voltage;
an electronic circuit arrangement to which the at least one fuel cell is electrically connected for supplying the electronic circuit arrangement with the electrical fuel cell voltage;
wherein the electronic circuit arrangement includes:
a first electrical voltage converter stage to which the electrical fuel cell voltage is appliable on an input side, the electrical fuel cell voltage convertible into a first electrical output voltage of the first electrical voltage converter stage via the first electrical voltage converter stage; and
a second electrical voltage converter stage electrically connected to the first electrical voltage converter stage and to which the first electrical output voltage is appliable on an input side, the first electrical output voltage convertible into a second electrical output voltage of the second electrical voltage converter stage via the second electrical voltage converter stage;

wherein an electrical interconnection of the first electrical voltage converter stage and the second electrical voltage converter stage is configured to be switchable between a first interconnection state and a second interconnection state.
