An absorption fluid reservoir having a fluid inlet for receiving gases during a charging event and a gas analysis unit for detecting unwanted impurities in the gases prior to being received in the reservoir and a control unit for eliminating the gases having the impurities.

Fluid reservoir having a gas sensor and a filter

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.

Gas absorption reservoir with optimized cooling

An electrochemical sensor element for determining the oxygen concentration in exhaust gases of internal combustion engines is described. The sensor element has a pump cell, which has a pump electrode situated on a surface of the sensor element facing the gas mixture, and a measuring gas electrode situated in a measuring gas area, the gas mixture entering the measuring gas area through a diffusion resistor. In addition, the sensor element has a reference electrode situated in a reference gas area. Another diffusion resistor is provided between the measuring gas area and the reference gas area.

Electrochemical sensor element

A device for dispensing hydrogen, in particular for supplying gaseous hydrogen for a fuel cell, has a reservoir, a gas connection for removing hydrogen from the reservoir and at least one heating device with which the reservoir is heatable for dispensing hydrogen. In addition, the reservoir is subdivided into at least two modules which are heatable independently of one another.

Device for dispensing of hydrogen

A polymer compound containing a ceramic powder and a polymer is described, the ceramic powder having a specific surface area of more than 1.8&middot;10 m /m and constituting more than 5 vol. % of the polymer compound, the polymer being shear resistant, and the pore sizes in the polymer compound being 3-15 nm. Furthermore, a method for manufacturing this polymer compound, its use, and a sintered body manufactured therefrom are also described.

Polymer compound, the production and use thereof, and sintered compacts produced therefrom

An oxygen measuring sensor is proposed, having a pump cell (,) with outer and inner pump electrodes (,) disposed on a solid electrolyte (,) which conducts oxygen ions, of which the inner pump electrode (,) is exposed in a diffusion conduit (,) to the gas to be measured. A further electrode (,) of a measuring cell (,) is disposed in the diffusion conduit (,) behind the inner pump electrode (,) in the direction of diffusion, at which a partial oxygen pressure, which lies at least approximately in the vicinity of lambda&equals;1, can be set by means of the pump cell (,), so that the pump cell (,) operates outside of the limiting current range of the current/voltage characteristic curve.

Method of measuring oxygen

Process and device for reducing pollutants, especially nitrogen oxides

An electrically tunable planar filter has a filter element including a substrate having an upper side and a wave-guide arranged on the upper side of the substrate, at least one tuning element composed of at least one material selected from the group consisting of a ferroelectric material and an antiferroelectric material with adjustable voltage applied to the tuning element and thereby with an adjustable dielectric constant, the tuning element being arranged at the upper side of the substrate.
