Abstract: A system and a method set the cockpit in a motor vehicle automatically. The method includes detecting an eye position of a driver in the motor vehicle using a driver observation camera; determining an optimized cockpit setting on the basis of the detected eye position, with the optimized cockpit setting comprising at least one position setting of a positionally adjustable display screen predetermined on the basis of the eye position; and implementing the optimized cockpit setting, with at least the positionally adjustable display screen being set to the predetermined position setting.

Abstract: The invention relates to a method to determine a content of a gas component in a gas mixture delivered recirculating through an anode chamber (12) or a cathode chamber (13) of a fuel cell (10), wherein the delivery takes place via a delivery device (26) functioning according to the positive displacement principle. The invention also relates to a fuel cell system (100) configured to execute the method. According to the invention, the content of the gas component is determined depending on geometric parameters (V, ?) and operating parameters (n, U, I) of the delivery device (26), as well as on thermodynamic state variables (p, T) of the gas mixture. The sought target quantity, for example a hydrogen component of an anode gas, can thus be determined in a simple and robust manner from quantities that are already known or measured.

Abstract: The invention relates to a method for switching off a fuel cell system (100) having a fuel cell stack (10), that has anode chambers (13) and cathode chambers (12), and a cathode supply (20) having a cathode supply path (21) for supplying an oxygenated cathode operating gas into the cathode chambers (12), a compressor (23) arranged in the cathode supply path (21) and a cathode exhaust path (22) for discharging a cathode exhaust gas from the cathode chambers (12). The method comprises the steps of: (a) Maintenance of the cathode chambers (12) under excess pressure while preventing a flow of cathode operating gas through the cathode chambers (12) while keeping the cathode operating gas that is present in the cathode chambers (12) oxygen-depleted; (b) Expansion of the oxygen-depleted cathode operating gas present in the cathode chambers (12) via the cathode supply path (31) [sic] and/or the cathode exhaust path (22), and (c) Separation of the cathode chambers (12) from the environment.

Abstract: A fuel cell system has a fuel cell stack composed of a plurality of fuel cells with a cathode side having a cathode inlet and a cathode outlet and an anode side having an anode inlet and an anode outlet. It is possible for a hydrogen-containing medium to be fed to the anode side and an oxygen-containing medium to be fed to the cathode side. It is further possible for at least some of the anode exhaust gas to be fed to the cathode side. An anode-side exhaust-gas line opens into an opening in a feed line for the oxygen-containing medium on a suction side of a compressor that feeds the oxygen to the cathode.
