Abstract

A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.
