Abstract: The invention relates to a method for detecting impurities in a gas tank having a predefined tank nominal volume, which method includes at least one of the following steps: (a) determining a theoretical pressure drop in the gas tank from a quantity of gas which is actually extracted, and comparing said theoretical pressure drop with a measured pressure drop in the gas tank, wherein a higher measured pressure drop indicates the presence of impurities; and (b) determining a gas volume which is theoretically present in the gas tank from the measured pressure and measured temperature in the gas tank, and comparing the gas volume which is theoretically present in the gas tank with the tank nominal volume in order to determine a volume taken up by impurities which are present.

Abstract: The invention relates to a fluid reservoir (1), especially an adsorption fluid reservoir comprising a fluid inlet (2). The fluid reservoir according to the invention is characterized by a gas analysis unit (3) for detecting unwanted impurities.

Abstract: The invention relates to a fluid reservoir, particularly a fluid reservoir with a sorption medium. According to the invention an improvement is provided by a device for the temperature control of the fluid reservoir.

Abstract: The invention relates to a fuel reservoir for gaseous fuel in a vehicle, in particular a sorption reservoir. The fuel reservoir is delimited by at least one wall and includes a sorption material that is contained in its interior. The fuel reservoir has a tank inlet valve containing a shut-off valve and a throttle restriction valve. The restriction of the gaseous fuel takes place inside the fuel reservoir.

Abstract: The invention proposes a vehicle (1) having a fuel cell system and/or an internal combustion engine and having at least one gas tank (2) for being filled with a gaseous fuel, in particular with natural gas or hydrogen, wherein a metal organic framework (MOF) is arranged in the interior of the gas tank (2) as a storage material for holding the fuel, wherein a comparatively high storage density is obtained and/or sufficient space for luggage or loading is made available in the vehicle (1). This is achieved according to the invention in that the gas tank (2) which comprises the metal organic framework (MOF) is embodied as a compressed-gas tank (2) for storing the gaseous fuel under pressure.

Abstract: The present invention relates to a gas pressure container having a minimum volume of 1 m3 and a prescribed maximum filling pressure for the uptake, storage and delivery of a fuel gas which is gaseous under storage conditions and is suitable for powering a vehicle by combustion of the fuel gas, wherein the gas pressure vessel has a filter through which the fuel gas can flow at least during uptake or during delivery, with the filter being suitable for removing possible impurities in the fuel gas from the stream and the impurities being able to reduce the storage capacity for the fuel gas of an adsorbent used for the storage of the fuel gas. The invention further relates to the use of such a gas pressure container for filling a further gas pressure container which is present in or on a vehicle and comprises an adsorbent for the storage of the fuel gas.

Abstract: A vehicle has a fuel system operative to chemically reform a fuel gas, a supply unit for supplying the fuel system with the fuel gas, and a gas reservoir provided with a storage volume for an intermediate storage of the fuel gas, the storage volume having a size that is changeable.

Abstract: A fuel cell system has a combustion device, a fuel cell unit and a reformer for transforming fuel into a reformed gas, the combustion device having at least one exhaust pipe as an outlet for exhaust gas, the use of such a fuel cell system resulting in a marked reduction in the additional energy that may be required for heating the transforming unit. This is achieved by positioning at least one heat exchanger unit at the exhaust pipe for heating a heating fluid and/or a fuel of the reformer, using the heat from the exhaust gas stream.

Abstract: A steer-by-wire steering system comprised of an electronically regulated steering positioner mounted to the steering gear of the front axle or to both front wheels of a vehicle together with an electronic steering regulator and a feedback actuator. A sensor senses the driver's selected direction from the steering wheel. Road feedback can be relayed to the driver through a feedback actuator via the steering wheel. The loss of road feel caused by the absence of the steering column, which normally strongly influences the driver's directional wish, is recreated by the feedback actuator.
