The invention relates to a modular range extender system (20) for an electrically driven motor vehicle (52), comprising a plurality of fuel cell basic modules (10), which each have a plurality of fuel cells connected in series and interfaces for supplying hydrogen and air as well as for discharging water and residual gas; a media supply device, which is designed to supply air and hydrogen to the fuel cell basic modules (10) via the interfaces and to discharge water and residual gas from the fuel cell basic modules (10) via the interfaces, wherein, in order to provide different outputs and/or voltages, different numbers of the fuel cell basic modules (10) are electrically connectable to one another in different series and/or parallel circuits and are configurable with the media supply device to form different variants of the range extender (22). The invention also relates to a circuit arrangement (40) for a vehicle electrical system of an electrically driven motor vehicle (52) and to an electrically driven motor vehicle having a circuit arrangement (40) of this kind.
