    Abstract: PURPOSE:To shorten the cycle time of occlusion/discharge of hydrogen gas and to improve its heat transfer performance by providing a plurality of columnar alloy storage sections for hydrogen occlusion with relatively small cross sections on a metallic plate. CONSTITUTION:A hydrogen gas passage 21 is connected to one end of a plurality of columnar alloy storage sections 20 for hydrogen occlusion of a storage container 1''. The alloy storage sections 20 are formed by laminating two metallic plates 23 formed with groove sections 23a approximately in parallel at a proper distance so that individual groove sections 23a face each other to form nearly circular cross sections. Accordingly, a heat transfer medium is introduced through a cylinder 32a and is discharged through a cylinder 31, on the other hand, hydrogen is introduced and discharged through a hydrogen gas inlet nozzle 21e and individual hydrogen gas passages 21, thereby occlusion and discharge of hydrogen gas can be performed uniformly in all alloy storage sections 20.

    Abstract: PURPOSE:To easily carry out the adsorption and release of gaseous hydrogen by forming a container for metallic hydride into a cylinder havng a plurality of metallic protrusions on the inside and a specified sectional shape and putting the container into a container which can be heated and cooled. CONSTITUTION:A plurality of metallic protrusions 11 having superior heat conductivity are attached to the inside of each cylindrical container 7 of Al or the like having superior heat conductivity and an arbitrary section, and a hydrogen feeding pipe 8 made of porous material is set at the central part of the container 7. The container 7 is packed with metallic powder 12 having a property of adsorbing and releasing gaseous hydrogen, it is out into a container 1 provided with a supply inlet 2 and a discharge outlet 3 for a heat medium and a refrigerant, and the pipe 8 in the container 7 is connected to a hydrogen distributing chamber 4 communicating with a gaseous hydrogen pipe 10. In order to facilitate the release or absorption of a large quantity of heat generated or absorbed during the adsorptin or release of gaseous hydrogen, a heat medium or a refrigerant is fed into the container 1. Thus, the density of metallic hydride 12 is not increased by expansion to prevent the deterioration of heat conduction, and the adsorption and release of gaseous hydrogen are easily carried out.

    Abstract: PURPOSE:To reactivate an alloy for occluding hydrogen by simple operation when the performance of the alloy is deteriorated by repeating the occlusion and release of hydrogen, by treating the alloy under pressure of hydrogen other than stationary running conditions. CONSTITUTION:A heat exchange tube 5 through which a heat medium from a process P is passed is installed in a regenerator 1 packed with an alloy for occluding hydrogen such as an Ni-Mg alloy. The regenerator 1 is connected to a tank 2 foe storing hydrogen with piping 3a, 3b to form a heat controller for the process P in which a surplus of heat and demand for heat are repeated at certain time intervals. When the heat medium in the process P has an excess of heat, hydrogen in the alloy is released by heating with the heat and the medium is cooled. The released hydrogen is fed to the tank 2 with a compressor 4. When the heat medium requires heat, hydrogen is occluded in the alloy and the medium is heated. When the performance of the alloy is deteriorated by repeating said operations, by closing a valve V5 and opening a valve V6, the heat medium is bypassed, and by evacuating the regenerator 1 or feeding highly compressed hydrogen, the alloy is reactivated.

    Abstract: PURPOSE:The stress on a strain gage is measured to detect the hydrogenation reaction rate and the rate of hydrogen flow into the hydrogen-occluding alloy is controlled on the basis of the detection to ensure steady and prompt control of the hydrogenation eaction rate of the metal hydride. CONSTITUTION:The major vessel 1 is filled with an alloy for hydrogen occulsion 2 and simultaneously provided with the filter 7a for the hydrogen gas inlet 7 and with a detector 21 filled with the same kind of the alloy on the reaction side embeded, then the lead 27 for the strain gage 26 is passed from the major vessel 1 through the seal mechanism 28 to the outside of the vessel. The lead 27 is connected to the stress-strain gage 29 and the hydrogen reaction rage converter 30, hydrogen comparison controller 31 and flow-rate control valve 4 are electrically connected to form a controll circuit. The resultant system compares the value calculated by the hydrogenation reaction rate converter 30 with the previously set rate and the flow-rate control valve 4 is operated according to the deviation to control the gas flow rate of the hydrogen to be occulded appropriately.

    Abstract: PURPOSE:To enable to effect heat exchange by a method wherein the rotary space of a reaction vessel is divided into a plurality of divisions to flow a medium to be heated and a heating medium and released hydrogen is flowed from the heating division to the division to be heated whereby the hydrogen is adsorbed to an alloy and emits a reaction heat. CONSTITUTION:A hydrogen gas circulating tube 2 and metallic powders for occluding the hydrogen gas are accommodated in the reaction vessel 1 and the hydrogen gas is circulated through the hydrogen gas circulating tube 2. The reaction vessel 1 in the division is heated by the heating medium, entered from the entrance 7 and discharged to the outlet 7', the hydrogen gas released by this heating is sent into the division at the bottom part thereof and is adsorbed to the metal for occluding the hydrogen gas, while the medium to be heated, flowed thereinto from the inlet 8 by reaction, is heated and is discharged from the outlet 8'. On the other hand, the top and the bottom of the vessel are converted by the rotation of the reaction vessel 1 and the hydrogen gas is adsorbed to the divisions in which the hydrogen gas was lost, while the medium is heated in this case.
