Abstract: A motor vehicle has an electrochemical cell, which includes an electrode stack of at least two electrodes in a parallel arrangement. The electrochemical cell is arranged outside an engine compartment of the motor vehicle in an accommodation compartment of the motor vehicle, the cross-sectional surface of which is tapered in the direction of the vertical axis of the vehicle. A cross-sectional surface of the electrochemical cell is thereby adapted to the cross-sectional surface of the accommodation compartment. Thus, particularly good use is made of the available space in the motor vehicle.

Abstract: A motor vehicle has at least one drive unit for generating a drive torque, and has an accelerator pedal which is acted on with a restoring force and which can be adjusted by an actuating travel in order to predefine a setpoint torque. The motor vehicle also has a control device which actuates the drive unit on the basis of the setpoint torque. The control device additionally determines a presently available drive torque, and as a function of the presently available drive torque, varies the characteristic curve of the accelerator pedal, which expresses the restoring force versus the actuating travel of the accelerator pedal.

Abstract: The invention relates to a method and a device for operating a high-temperature fuel cell using liquid fuel, preferably diesel oil, where a reformer for the liquid fuel precedes the high-temperature fuel cell on the anode side. A recirculation line for the hot anode exhaust gas is provided, which departing from the outlet side of the anode of the high-temperature fuel cell leads to the inlet side of the reformer, an injector for spraying or injecting the liquid fuel into the hot anode exhaust gas being located upstream of a compressor preceding the reformer. The resulting cooling of the anode exhaust gas will permit the use of conventional positive displacement or rotary pumps in the anode circuit.

A reduction in the volume shrinkage and an increase in the mechanical hardness during operation of the methanol reforming catalyst are achieved by the preparation process.
