Abstract: An electric heating device (20) is described which has at least one first electrically conductive component (21), at least one heating layer (22) and at least one second electrically conductive component (23). According to the invention, it is envisaged that the first electrically conductive component (21) and/or the second electrically conductive component (23) is/are produced and/or arranged on the heating layer (22) by means of a thermal spraying process. Alternatively or additionally, according to the invention, it is envisaged that the electrically conductive components (21, 23) and the heating layer (22) are arranged with respect to one another in such a way that a current flow perpendicularly to the plane of the heating layer (22) and/or in the direction of the plane of the heating layer (22) is realized or can be realized. In order to produce an assembly (10), such a heating device (20) can preferably be arranged on a substrate element (11). Furthermore, a suitable production method is described.

Abstract: The invention relates to a storage tank for storing a sorbent material. Said storage tank comprises a pressure vessel, a connecting element to an external supply system, at least on sorbent material which contains a sorbent and an adsorbate that adsorbs thereto, especially a gaseous fuel, preferably hydrogen, and which is stored in the storage tank at least during proper use of the storage tank, and a conduit for feeding and/or discharging sorbent material into/from the storage tank. At least one second duct is provided for supplying and/or evacuating a gas (gas duct). The sorbent is formed on the basis of heavy-duty adsorbents based on activated carbon in the form of discrete, activated carbon grains, preferably spherical ones. At least 70 percent of the entire pore volume of the heavy-duty adsorbents are formed by microspores having a diameter of ?20.

Abstract: Among other things, a method for the production of a modified material, for example, a carbon material, is described, having the following steps: Generation of a high-frequency field in a chamber (2) of a plasmatron (1); introduction of a plasma gas into chamber (2); generation of a plasma with the plasma gas by the high-frequency field; and introduction of initial material into the plasma. In addition a plasmatron (1) is described for the production of a modified material (M), having: a chamber (2), at least one high-frequency inductor (3) disposed in at least one region of chamber (2), a gas supply line (10, 11) for introducing a plasma gas into the region of a high-frequency field generated by high-frequency inductor (3), and a material supply line (4) for blowing in initial material with a transport gas into the plasma generated by high-frequency inductor (3) with the plasma gas. Finally, it also describes a modified carbon material which is correspondingly produced.

Abstract: A device for measuring the filling level of a medium—for example hydrogen—in a storage container of a storage device—for example a tank system. To provide a simple and direct possible way of accurately determining the filling level of the storage container even without knowing the amount of medium already discharged or irrespective of uncontrollable losses, the device is designed as a measuring device for measuring the nuclear magnetic resonance of the medium located in the storage container. For this purpose, the device has a measuring head with, for example, a permanent magnet and a measuring coil, via which a static magnetic field and an electromagnetic alternating field are generated in the measuring head. The electromagnetic alternating field is generated in a transmitter, which is connected to the measuring head by a bridge circuit.

Abstract: A closed storage reservoir has at least one feed and discharge line for compressed gas and, in its interior, a gas flow control system which connects the feed and discharge line to a solid filling for storing the compressed gas in the interior. To ensure the highest possible specific storage capacity of the device and to enable the device to be used as a tank system for a fuel cell, the solid filling comprises carbon nanostructures which are joined to form larger, cohesive conglomerates. A device for measuring the filling level of the compressed gas in the storage vessel may be a device for measuring the nuclear magnetic resonance or a device for measuring the mass flow rates of the compressed gas. A temperature sensor and a heating/cooling device having an inlet connection piece and an outlet connection piece for a heating/cooling medium and a cooling passage connected to the connection pieces are provided in order to set a defined temperature in the storage vessel.

Abstract: A gas accumulator for storing pressurized gases, in particular gaseous fuels such as hydrogen or the like, which gas accumulator has a sealed vessel which is provided with a valve-actuated feed line and outlet line for the pressurized gas and with a solid packing of carbon nanostructures. To increase the storage capacity of a gas accumulator of this type significantly, the particles of the carbon nanostructures are compacted to form larger coherent conglomerates having an apparent density which is increased in comparison with the apparent density of the originally loose particles. The compaction can be carried out, for example, by ordering the carbon nanostructures in their orientation to one another, or else by forming the conglomerates by pressing non-ordered carbon nanostructures.
