Abstract

A motor vehicle has a drive combustion engine and a power supply system for supplying electric consuming devices on-board the motor vehicle. The power supply system includes a fuel cell system and a battery coupled to the fuel cell system. The energy and/or material currents of the drive combustion engine and the fuel cell system are coupled together.

Claims

1. Motor vehicle comprising a drive combustion engine and a power supply system for supplying electric consuming devices on-board the motor vehicle, the power supply system including a fuel cell system and a battery coupled to said fuel cell system, such that energy and/or material currents of the drive combustion engine and the fuel cell system are operatively coupled together, wherein a gas generating system of the fuel cell system, an exhaust gas line of the drive combustion engine and an exhaust gas treatment catalyst in the exhaust gas line of the drive combustion engine are operatively coupled thermally.
