Abstract
A vehicle having a drive unit, a drive train, at least one driven wheel, an energy storage means and power electronics for supplying electrical loads in the vehicle. An electrical machine is electrically connected to the power electronics, which are electrically connected to an electrolyzer. One output of the electrolyzer is connected via a media line to an energy store, and one input of the electrolyzer is connected to a water tank. The storage contents of the energy store are supplied to a fuel cell system and/or to the drive unit for power production.
