[0002] Existing solid hydrogen storage devices can quickly charge hydrogen and improve the stability of the hydrogen release rate, especially improve the thermal conductivity in the radial direction, because the heat dissipation of the hydrogen storage device is mainly achieved by the convection between the outside and the coolant; regarding the problem of hydrogen charging and discharging rates, after directly loading the powder and activating, the D50 particle size is about 10μm - 45μm, and the thermal conductivity is ~0.1 W / (m·K), while the thermal conductivity of the compacted material is 3 - 10 W / (m·K), with a difference of dozens of times in thermal conductivity. The hydrogen storage material itself is basically saturated in about 5 minutes, and the fundamental reason for the slow hydrogen absorption and release rates measured in practice is the poor thermal conductivity of the material.

Specific Embodiment 1:

[0055] As Figure 1 and Figure 2 shown, a solid-state metal hydrogen storage device includes a hydrogen storage tank 1. The hydrogen storage tank 1 includes an inner tank body 102. A plurality of storage bins 104 spaced by a partition plate 105 and a partition board 110 are arranged inside the inner tank body 102. A plurality of heat dissipation fins are arranged in the storage bins 104. A plurality of flexible buffer materials 106 for buffer protection are arranged between the inner tank body 102, the partition plate 105 and the partition board 110.

[0056] The working principle and beneficial effects of this embodiment are as follows: The storage bin 104 stores alloy powder, which is one or more of rare earth-based AB5 type, titanium-based AB2 type, AB type, and titanium-vanadium BCC solid solution type hydrogen storage alloys;

[0057] The partition plate 105 is slidably connected to the inner tank body 102.

[0058] Preferably, an air duct 103 is arranged inside the inner tank body 102. The air duct 103 penetrates through the storage bin 104 and the partition plate 105. One end of the air duct 103 is fixedly connected to the inner wall of the inner tank body 102, and the other end of the air duct 103 penetrates through the inner tank body 102.

[0059] Preferably, the air duct 103 is a sintered body of copper powder or stainless steel powder, and the filtration accuracy does not exceed 50 μm. The function of the air duct is to make hydrogen gas evenly distributed in the inner tank body 102, ensure sufficient contact between hydrogen gas and the hydrogen storage alloy powder, and improve the charging and discharging uniformity of the hydrogen storage alloy powder;

[0060] Preferably, an outer shell body 101 is arranged outside the inner tank body 102, and the outer shell body 101 is fixedly connected to the inner tank body 102 through a fixing block 107;

[0061] At least one set of coolant inlets and outlets 109 are arranged on the outer shell body 101;

[0062] Preferably, an air inlet 108 is arranged on the outer shell body 101. The air inlet 108 is located at the place where the air duct 103 penetrates through the inner tank body 102, and one end of the air duct 103 penetrating through the inner tank body 102 is located inside the air inlet 108;

[0063] Preferably, a hydrogen filter is arranged at the air inlet 108. The hydrogen filter is a sintered body of copper powder or stainless steel powder, and the filtration accuracy does not exceed 5 μm, preventing extremely fine particles generated during the hydrogen absorption and desorption process of the hydrogen storage alloy powder from entering the gas pipeline along with hydrogen gas;

[0064] Several partition plates 105 are designed inside the inner tank body 102. A storage bin 104 is formed between each partition plate 105. The storage bin 104 stores alloy powder. A flexible buffer material 106 is arranged outside the partition plate 105 of each storage bin. By using the characteristics of the flexible buffer material 106 to offset the stress generated by the hydrogen absorption expansion of the hydrogen storage alloy, the damage to the inner tank body 102 caused by the expansion of the hydrogen storage alloy can be effectively reduced. At the same time, by using the compression effect of the flexible buffer material 106 on the solid alloy powder, the solid hydrogen in each storage bin 104 can be compacted, so as to ensure that the solid hydrogen storage powder does not move along with the movement of the inner tank body 102 during transportation, prevent the migration of the hydrogen storage powder, and thus improve the transportation safety of solid hydrogen;

[0065] An outer casing 101 is provided outside the inner tank body 102, and a coolant is poured between the outer casing 101 and the inner tank body 102, so that the outer wall of the inner tank body 102 is in contact with the coolant, ensuring uniform heat dissipation of the inner tank body 102 and also ensuring the efficiency of solid-state hydrogen storage. When the alloy powder in the storage bin reacts with hydrogen to absorb hydrogen, a large amount of heat will be released;

[0066] The positions of the coolant inlets and outlets 109 are specifically selected according to the connection state of the storage and transportation tank body, ensuring the practicability of the device; at the same time, it solves the problems of poor heat exchange performance, poor thermal conductivity, and short service life of the solid-state hydrogen storage device. Specific Embodiment Two:

[0068] As Figure 1 and Figure 2 shown, for a solid-state metal hydrogen storage device, the flexible buffer material 106 is a spring or an elastic porous metal material;

[0069] The heat dissipation fins are one of an aluminum disc, a copper disc, and a metal mesh.

[0070] The working principle and beneficial effects of this embodiment are: adding heat dissipation fins (thin aluminum discs, copper discs, or corresponding metal meshes) in the solid-state hydrogen storage device to increase the thermal conductivity of the hydrogen storage device, and regulating by adjusting and adding the spacing and quantity between the heat dissipation fins;

[0071] The flexible buffer material (spring, highly elastic porous metal material, etc.) can, on the one hand, prevent the damage to the hydrogen storage tank caused by the hydrogen absorption expansion of the solid-state hydrogen storage alloy powder, and at the same time press the solid-state alloy powder tightly to reduce the porosity of the alloy powder and increase the heat conduction of the hydrogen storage device. Specific Embodiment Three:

[0073] As Figure 1 , Figure 2 and Figure 18 shown, for a solid-state metal hydrogen storage device, the partition plate 105 is slidably connected inside the inner tank body 102; a gas guide pipe 103 is provided inside the inner tank body 102, passing through the storage bin 104, the partition plate 105, and the partition board 110. One end of the gas guide pipe 103 is fixedly connected to the inner wall of the inner tank body 102, and the other end of the gas guide pipe 103 penetrates the inner tank body 102;

[0074] The outer of the inner tank body 102 is wrapped with an outer casing 101; a cooling channel is provided between the inner tank body 102 and the outer casing 101; the outer casing 101 and the inner tank body 102 are fixedly connected by fixing blocks 107;

[0075] At least one group of coolant inlets and outlets 109 is provided on the outer casing 101;

[0076] An air inlet 108 is provided on the outer housing 101. The air inlet 108 is located at the place where the air guide pipe 103 penetrates the inner tank body 102. One end of the air guide pipe 103 penetrating the inner tank body 102 is located inside the air inlet 108.

[0077] The working principle and beneficial effects of this embodiment are as follows: The presence of the outer housing 101 facilitates the protection of the inner tank body 102 and heat dissipation. An outer housing 101 is arranged outside the inner tank body 102, and a coolant is filled between the outer housing 101 and the inner tank body 102, so that the outer wall of the inner tank body 102 is in contact with the coolant, ensuring uniform heat dissipation of the inner tank body 102 and also ensuring the efficiency of solid-state hydrogen storage. When the alloy powder in the storage bin reacts with hydrogen to absorb hydrogen, a large amount of heat will be released.

[0078] Regarding the issue of hydrogen charging and discharging rates, after direct powder loading and activation, the D50 particle size is about 10 μm to 45 μm, and the thermal conductivity is about 0.1 W / (m·K), while the thermal conductivity of the compacted material is 3 to 10 W / (m·K). The difference in thermal conductivity is dozens of times. The hydrogen storage material itself is basically saturated in about 5 minutes, but the fundamental reason for the slow hydrogen charging and discharging rates measured in practice is the poor thermal conductivity of the material and the accumulation of a large amount of heat.

[0079] The reaction bed heat transfer data mainly includes λeff and also hw. An overview is shown in Figure 18 . Although the effective thermal conductivity of a pure powder bed or particle bed is very low, about 0.1 to 1 W / m·K, significant improvements can be obtained even at high pressures, such as the hydrogen pressure in metal hydrides, through the measures described in Section 2. Of particular interest are anisotropic porous graphite matrices, which produce an effective thermal conductivity λeff in the radial direction on the order of 5 to 30 W / m·K, while in the axial direction, the effective thermal conductivity λeff is on the order of <1 W / m·K. They have been used together with ammonium salts. Consolidated activated carbon AC and zeolite NaX, 4A beds, form porous blocks and include highly porous metal foams Ni, Cu as heat transfer matrices, resulting in an effective thermal conductivity λeff of about 5 to 30 W / m·K. Regarding metal hydrides, two main technologies have shown good results. One type of solid-state metal hydrogen storage device uses a metal matrix with a highly porous metal foam and an internal fin structure; another type of solid-state metal hydrogen storage device is obtained by mixing metal hydride powder with aluminum powder and cold pressing it into small compacts, with or without subsequent sintering. Depending on the amount of Al powder used, a very high λeff can be obtained. For example, for 31 wt% of A1, λeff ≈ 23 W / m·K.

[0080] In addition to the thermal conductivity itself, the contact thermal resistance of the bed wall must also be observed. Values up to 1000 W / m·K can be obtained for an anisotropic graphite matrix; similar data have been determined for an Al foam matrix that has been tapped to fit well against the tube wall. Higher values can be obtained when the metal matrix can be welded to the reaction bed wall. The thermal resistance of the bed wall is generally negligible, even for a stainless steel wall material with λ = 17 W / m·K. Specific Embodiment 4:

[0082] As Figure 1 —and Figure 17 shown, a solid-state metal hydrogen storage device, wherein the inner tank 102 is wrapped and installed with the outer shell 101 through a tank shell packaging device;

[0083] The tank shell packaging device includes an operation rack 2. One end of the operation rack 2 is provided with a stacking transporter 3 to transport a plurality of inner tanks 102 into a separator 4. After being separated by the separator 4, the inner tanks 102 are transported into a spraying transporter 5 for transportation and spraying. The spraying transporter 5 transports the sprayed inner tanks 102 to a clamping outer winding table 9. The clamping outer winding table 9 winds the metal thin shell unrolled by an unwinder 6 and an unwinding table 7 onto the inner tank 102 to form the outer shell 101. The inner tank 102 with the outer shell 101 after winding is transported out by a tail transporter 8 for welding; a plurality of sensors and a power supply are arranged on the operation rack 2.

[0084] The working principle and beneficial effects of this embodiment are as follows: The inner tank 102 to be wrapped and installed with the outer shell 101 is added to the stacking transporter 3 on the operation rack 2 for transportation. The transported inner tanks 102 are stably adjusted in direction and interval by the separator 4, so as to facilitate the stable and directional interval transportation of a plurality of inner tanks 102 processed simultaneously. Then, the inner tanks 102 are added to the spraying transporter 5 and are transported by flipping in the spraying transporter 5, so as to achieve all-round spraying on the surface of the inner tank 102. Anti-corrosion, rust-proof, and wear-resistant coatings are applied to the surface of the hydrogen storage tank by spraying, brushing, etc. to provide an additional protective layer; special coating technologies can also improve the surface reflectivity or ultraviolet resistance;

[0085] The sprayed inner tank body 102 is transported into the clamping outer coiling table 9 by the spraying transporter 5. The clamping outer coiling table 9 drives the clamping to lift the inner tank body 102, and the metal thin shell unrolled by the uncoiler 6 is attached to the unrolling table 7. The clamping outer coiling table 9 drives the clamped and lifted inner tank body 102 to rotate, so as to wind the sticky metal thin shell on the surface of the inner tank body 102. Then, after cutting by the unrolling table 7, the clamping outer coiling table 9 resets the inner tank body 102. Finally, it is transported out by the tail transporter 8 for welding to seal the metal thin shell, and the wrapping and installation of the outer shell 101 of the inner tank body 102 can be completed, thus forming a solid metal hydrogen storage device. According to different requirements, outer shells 101 of different materials and styles can be selected for use, which is convenient for protecting the inner tank body 102 and facilitating heat dissipation.

A chute is arranged on the partition transport plate 42 to limit the eccentric drive shaft 47. The eccentric drive shaft 47 running eccentrically drives the connecting rotating roller 43 to rotate eccentrically around the center of the turntable of the partition driver 41 through the fixed seat.

[0097] The clamping outer winding platform 9 includes a clamping driver 91. The clamping driver 91 is fixed on the operation frame 2 through a limit fixing platform 92. The clamping driver 91 drives the driving threaded cylinder 93 to rotate. The driving threaded cylinder 93 is connected with a driving screw platform 94 through a threaded fit. A hinge seat is rotatably arranged in the driving screw platform 94. The hinge seat is hinged to a hinge platform 95 through a hinge rod, and a winding driving clamping platform 96 driven by a motor is fixed on the hinge platform 95.

[0098] The working principle and beneficial effects of this embodiment are as follows: The inner tank body 102 with the fixed block 107 after spraying is transported by the transport rotating wheels and added into the two symmetrical clamping outer winding platforms 9. One of the winding drive clamping platforms 96 is driven by rotation, while the other does not need to be; control the clamping driver 91 to drive, and then drive the threaded barrel 93 to rotate.

A hinge seat is rotatably arranged in the driving screw platform 94, and the hinge seat is hinged to the hinge platform 95 through a hinge rod. Then, the winding drive clamping platform 96 driven by a motor fixed on the hinge platform 95 pushes the inner tank body 102 with the fixed block 107 inward and clamps it on the symmetrical winding drive clamping platforms 96. Continuing to push inward will lift the inner tank body 102 with the fixed block 107 to a certain height, so that the inner tank body 102 with the fixed block 107 is separated from the surface of the operation frame 2. Driven by the winding drive clamping platform 96, the inner tank body 102 with the fixed block 107 rotates, which is convenient for winding and wrapping with a metal thin shell. Specific Embodiment VIII:

[0100] As Figure 1 — Figure 17 shown, for the tank shell packaging device, the lowermost unwinding platform 7 includes a fixed side plate 71, a rotating roller 72 is rotatably arranged on the fixed side plate 71, a connecting side platform 73 is fixed on the fixed side plate 71, a radian fitting platform 74 is fixed on the connecting side platform 73, a glue adding groove 75 is arranged on the radian fitting platform 74, and a glue adding roller 78 is driven by a motor in the glue adding groove 75; a cutting motor 76 is fixed on the radian fitting platform 74, and the cutting motor 76 drives the cutting rotating blade 77 to slide in the radian fitting platform 74 through screw thread fit; the metal thin shell unwound by the unwinder 6 is added into the glue adding groove 75 through the rotating roller 72 and fits on the side end of the inner tank body 102 of the clamping outer winding platform 9.

[0101] The tail transporter 8 is driven by a motor to rotate at the tail end of the operation frame 2.

[0102] The working principle and beneficial effects of this embodiment are as follows: The unwinder 6 unwinds the metal thin shell continuously passing through the rotating rollers 72 on different unwinding platforms 7, thereby playing a role in adding support. The lowest unwinding platform 7 is fixed with an arc-fitting platform 74. Two clamping outer winding platforms 9 clamp the inner tank body 102 with a fixing block 107 upwards, so that the inner tank body 102 fits the metal thin shell between the arc-fitting platforms 74. A glue adding groove 75 is arranged on the arc-fitting platform 74, and a glue adding roller 78 is arranged in the glue adding groove 75 driven by a motor. By regularly adding glue on the glue adding roller 78, the inner wall of the added metal thin shell has viscosity, which is convenient for winding on the inner tank body 102. The rotating inner tank body 102 wraps the surface of the metal thin shell being wound around the outer end of the fixing block 107 to form an outer shell body 101, thereby realizing the formation of the outer shell body 101 wrapped around the hydrogen storage tank 1; then, on the arc-fitting platform 74, a cutting motor 76 drives the cutting rotary blade 77 to slide in the arc-fitting platform 74 through the screw thread cooperation, completing the cutting of the added metal thin shell, thereby facilitating the automatic formation of the outer shell bodies 101 of multiple inner tank bodies 102 with fixing blocks 107; after the wrapping is completed, the two clamping outer winding platforms 9 are reset, and are transported out through the conveyor belt on the tail conveyor 8 or the transport blocks on the conveyor belt, completing the wrapping. Subsequently, the metal thin shell is welded or bonded to complete the processing and preparation.
