DETAILED DESCRIPTION OF THE INVENTION The detailed description of the present invention and the preferred embodiments of the present invention are set forth in the first embodiment of the present invention. Fig. 2 is a longitudinal sectional view taken along line A-A of Fig. 1. Fig. 3 is a cross-sectional view of the cross section taken along line B-B of Fig. 1. Fig. 4 is a view showing an embodiment of a second embodiment of a hydrogen storage device 100 of the present invention. Fig. 5 is a view showing an embodiment of a third embodiment of an argon storage device 100 of the present invention. Fig. 6 is a view showing an embodiment of a fourth embodiment of a hydrogen storage device 100' of the present invention. Fig. 7 is a view showing an embodiment of a fifth embodiment of a hydrogen storage device 100' of the present invention. As shown in FIG. 1 to FIG. 3, this embodiment is a hydrogen storage device 100, which can be used to store hydrogen gas, which includes: a first housing ίο; at least one hydrogen storage container 20; at least one stress buffer Member 30; and a second housing 40. As shown in FIG. 2, a first space 11 is formed inside the first casing 10 and has a first opening 12 in the first casing 10, and the first space 11 can be communicated with the outside by the first opening 12, and Helium can be introduced into the first space 11 from the first opening 12. The first housing 10 may include at least one recessed portion 13, and the recessed portion 13 may be formed by extending the first housing 10 toward the first space 11, and the recessed portion 13 may be formed in a cylindrical shape. The hydrogen storage container 20 may be a capless annular container that is disposed in the first space 11 for loading a hydrogen storage material. Hydrogen enters the first space 11 from the outside through the first opening 12 and is in contact with the hydrogen storage material stored in the hydrogen storage container 20 to store hydrogen. The first space 11 may include at least two hydrogen storage containers 20 according to the size of the space. However, after the hydrogen storage reaction of the argon storage material, the deformation of the volume expansion does not affect the first casing 10, and can have a space extending around. The argon storage containers 20 may be arranged in the first space 11 at a specific interval. The argon storage material may be a high temperature type, medium temperature type or low temperature type hydrogen storage material, and may be a hydrogen storage alloy, more particularly a metal hydride. It can be seen that the hydrogen storage material is not single selective, so each hydrogen storage container 20 can independently load hydrogen storage materials with different characteristics. The stress buffering member 30 is disposed in each of the hydrogen storage containers 20 and the first housing 10. The stress buffering member 30 may be a spring member 31, a sponge member, a metal dome 32 or other elastomer, in order to buffer the stress generated on the hydrogen storage container 20 due to the volume expansion of the hydrogen storage material. As shown in Fig. 4, the stress buffering member 30 may be a metal spring member 31 that connects the hydrogen storage container 20 to the side wall of the first 201128106 casing 10. In addition to the stress generated by the volume change of the buffered hydrogen storage material, the spring member 31 can further provide a heat conduction function by the property of the metal thermal conductivity to assist in the transfer of heat energy during the hydrogen absorption and desorption reaction of the argon storage material. As shown in FIG. 5, the stress buffering member 30 may also be a metal elastic piece 32 composed of a metal curved sheet, wherein the metal elastic piece 32 has a curved end portion 33 and two vertex end portions 34, wherein the curved surface end portion 33 In combination with the hydrogen storage container 20, the apex end portion 34 is coupled to the sidewall of the first housing 10. Since the metal dome 32 is made of metal and has a certain elastic force, it also has the functions of heat conduction and buffering. As shown in FIGS. 2 and 3, the second housing 40 surrounds the first housing 10 and forms a second space 41 with the first housing 10, and the second housing 40 additionally has an inlet. The valve 42 and an outlet valve 43 allow the second space 41 to communicate with the outside, and form a flow path 44 from the inlet valve 42 to the outlet valve 43 in the second space 41 for at least one heat transfer medium from the outside to the inlet valve. 42 flows into the second space 41 and flows out of the outlet width 43. When the first housing 10 includes the recessed portion 13, the flow passage 44 can be made to have a curved flow passage 44, and the recessed portion 13 can further include a baffle baffle 45, and the baffle baffle 45 is disposed on the recessed portion The second housing 40 is parallel to the sidewall of the recess 13 so that the heat transfer medium can flow into the recess 13 so that the heat generated by the hydrogen storage material near the center of the hydrogen storage device 100 can be heated. The transfer method effectively performs heat exchange. As shown in Fig. 2, the arrow flow direction indicates the direction in which the heat transfer medium flows in the second space 41, and the heat transfer medium flows into the second space 41 from the inlet valve 42 and flows through the choke baffle 45 and the recessed portion 13 through the 201128106. The curved passage 44 is formed, and after flowing through the curved flow passage 44, the heat transfer medium flows out of the second space 41 from the outlet valve 43 so that the heat transfer medium can simultaneously be inside and outside the hydrogen storage container 20. The hydrogen storage material is subjected to heat exchange to adjust the temperature of the hydrogen storage container 20, wherein the heat transfer medium may be selected from one or a combination of the following groups: water, gas, oil, and hydrocarbon. In the hydrogen storage device 100, since both the first housing 10 and the second housing 40 need to transmit heat to assist in regulating the temperature of the argon storage container 20, the first housing 10* and the second housing 40 can be independent. It is composed of heat transfer material. However, in order to avoid the influence of external temperature on the overall hydrogen storage device 100, the heat insulating design can be further utilized to block the external environment. As shown in FIG. 2, a heat insulating layer 50 may be further disposed to be wrapped around the second casing 40, or a third casing 60 may be additionally constructed outside the second casing 40 as shown in FIG. And the third housing 60 can also be composed of a heat transfer material independently. The third casing 60 is surrounded by the second casing 40 and forms a third space 61 between the second casing 40, and a heat insulating member (not shown) can be further disposed in the third space 61. In order to reduce the heat transfer between the external environment and the hydrogen storage container 20.

The hydrogen storage container 20 may be a circular disk-shaped container and disposed in the first space 201128106 11 for loading a hydrogen storage material, and the second hydrogen storage container 20, and arranged at a specific interval in the first body. Including at least the hydrogen container 20 can be independently loaded into the characteristic column space 11 respectively, and the reservoir is from the outside via the first housing 1. The hydrogen hydrogen storage material is contacted to store the argon gas, and The first space 11 and the medium temperature type or low temperature type hydrogen storage material. The I material may be a high temperature type, and the = punching member 30 is disposed in each of the gas storage containers 2 and the first casing 1 _ On the hydrogen storage container 20, the stress generated by the hydrogen material during hydrogen absorption and depletion, wherein the stress buffering member 30 may be a spring construction 31, a sponge member, a metal dome 32 or other elastomer. As shown, the stress buffering member 30 is a metal spring member Μ and can be coupled between the hydrogen storage container 20 and the first housing 1 ,. The metal spring member 31 has a stress generated by a buffered hydrogen storage material volume change. In addition, it can be further protected by its metal. Hebi Wei assists in the transfer of energy during the hydrogen absorption and desorption of the i-material.
