摘要： A method for manufacturing tanks for storing or containing a fluid under pressure and a method for manufacturing pipes for containing or channeling a fluid under pressure, such as for storing, containing or channeling hydrogen, natural gas or a hydraulic fluid. The method is less complex than known procedures, can be employed in a continuous or semi-continuous manner and allows for a lower thickness of the shell made from the fibres. The method comprising providing a liner having a cylindrical portion with two ends and two dome portions at the respective ends of the cylindrical portions or a liner having a cylindrical portion and one or two open ends; fabricating a tube of fibre filaments by means of the pullwinding method; and wrapping the tube of fibre filaments onto the liner such that at least the cylindrical portion of the liner is enclosed by the tube of fibre filaments.

摘要： The invention relates to a cold start apparatus for an exothermic hydrogen consumer such as a fuel cell and also a method for operating an exothermic hydrogen consumer having a metal hydride store or hydrogen supply from a reformer. It is an object of the present invention to provide a fuel cell having an efficient cold start apparatus, which can be taken into operation immediately and does not require any pressure tank. Furthermore, the cold start apparatus should be available for an unlimited number of starting operations. The object is achieved by an apparatus for operation of a fuel cell or another exothermic hydrogen consumer, which comprises at least one starter tank comprising a metal hydride having cold start properties and also at least one operating tank comprising at least one intermediate-temperature hydride or at least one reformer, wherein the starter tank is in fluidic communication with the exothermic hydrogen consumer and the operating tank or the reformer, wherein the first starter tank comprises a metal hydride which has an equilibrium pressure for desorption at a temperature of −40° C. of at least 100 kPa and further comprises a cooling device in order to be able to be reloaded with hydrogen by the operating tank or the reformer while the fuel cell is being supplied.

摘要： The present invention relates to a system and method for the efficient heat management of a low-temperature fuel cell which is supplied from a metal hydride store. The system of the invention makes it possible to achieve, for example, discharge temperatures of the metal hydride store of about 180° C. in the case of low-temperature fuel cells operated at about 85° C.

摘要： The invention relates to a gas circulation system (1) for transporting heat from a high-temperature source (5) to a heat consumer (7), having a pipe system (2), through which a gaseous heat transfer medium flows, wherein part of the pipe system (2) is formed as a heat exchanger (4) following on from the high-temperature source (5), in which heat is transferred from the high-temperature source (5) into the heat transfer medium, and wherein part of the pipe system (2) is formed as a heat sink (6), in which the heat transferred to the heat transfer medium can be transferred to a heat consumer (7), or as a heat consumer. One or more gas flow enhancers (8) functioning according to the Coandă effect and/or the Venturi effect, which are supplied with pressurized impulse gas, are provided in the pipe system (2), in order to propel the heat transfer medium in the pipe system (2) in a flow direction (3).

摘要： The present invention relates to a composite material for hydrogen storage based on metal hydrides and to a method of operating a hydrogen storage system based on metal hydrides capable of releasing and absorbing hydrogen. Such hydrogen storage systems based on metal hydrides may be applicable as a fuel source for a fuel cell. The composite material for hydrogen storage comprises a powder or pellets of a hydride and a phase changing material (PCM), wherein the PCM is an encapsulated phase changing material (EPCM) which is homogeneously dispersed within the powder or pellets of the hydride.
