Description

[0002] With the increasing global demand for clean energy, hydrogen energy equipment is gradually entering the market. Current hydrogen storage methods include: high-pressure gaseous hydrogen storage, liquid hydrogen storage, and solid-state hydrogen storage using hydrogen storage materials as the medium. Solid-state hydrogen storage is a crucial future direction for hydrogen storage technology due to its advantages such as high volumetric hydrogen storage density, low-pressure safety, and high hydrogen purity.

[0003] Currently, most existing hydrogen storage devices are fixed in place, which limits the application scope of hydrogen energy to some extent. This design not only increases the manufacturing cost of the equipment but also restricts its application in space-constrained environments, leading to many shortcomings of traditional energy storage and transportation methods, such as low efficiency and significant safety hazards. At the same time, due to the large size and difficulty in moving the equipment, hydrogen energy is difficult to achieve distributed application. In scenarios with diversified energy demands, fixed-installation hydrogen storage devices cannot meet diverse needs, which also limits the application scope of hydrogen energy. Utility Model Content

The multiple hydrogen storage cylinders 2 are placed side by side in the cavity 10 and connected to the manifold 3 via hoses. The gas path assembly 4 is used to fill hydrogen into the hydrogen storage cylinders 2 or to discharge hydrogen from the hydrogen storage cylinders 2. The gas path assembly 4 is connected to the manifold 3. The liquid pipeline assembly 5 is connected to the cavity 10 and is used to input liquid into the cavity 10 for heat exchange with the hydrogen storage cylinders 2.

[0024] In some embodiments, the housing 1 has at least one limiting plate 11 that is fixed horizontally inside the cavity 10. The limiting plate 11 is provided with a plurality of limiting holes that are adapted to the shape of the hydrogen storage bottle 2. The plurality of hydrogen storage bottles 2 are placed vertically in the cavity 10 through the limiting holes one to one.

[0025] In this embodiment, two limiting plates 11 are provided in the housing 1, and the two limiting plates 11 are arranged vertically at intervals.

[0026] Furthermore, the two limiting plates 11 divide the cavity 10 into three different cavity layers: upper, middle, and lower. In order to enable the liquids in the three different cavity layers to communicate with each other, each limiting plate 11 is provided with at least one liquid passage hole, and the liquids in the different cavity layers communicate with each other through the liquid passage hole.

[0027] In some embodiments, the gas path assembly 4 includes a gas supply pipe 41 connected to the manifold 3, a connecting pipe 42 connected to the gas supply pipe 41 of one or two hydrogen storage modules via a three-way or four-way connector, and a hydrogen filling port 43 and a hydrogen discharging port 44 communicating with the connecting pipe 42. Hydrogen is filled into each hydrogen storage cylinder 2 through the hydrogen filling port 43, and the hydrogen stored in the hydrogen storage cylinder 2 is discharged through the hydrogen discharging port 44. A one-way valve is installed on the pipe between the hydrogen filling port 43 and the connecting pipe 42, and a one-way valve is installed on the pipe between the hydrogen discharging port 44 and the connecting pipe 42.

[0028] In some embodiments, the gas path assembly 4 further includes a safety valve 45, a pressure sensor 46, and a ball valve 47. The safety valve 45 ensures the safety of the gas path assembly 4 and the hydrogen storage tank 2. When the pressure in the hydrogen storage tank 2 and the pipeline is too high, the safety valve 45 automatically releases the pressure to prevent damage to the hydrogen storage tank 2 and the pipeline due to excessive pressure. The safety valve 45 is connected to the connecting pipe 42 and is arranged in parallel with the hydrogen filling port 43 and the hydrogen discharging port 44. The pressure sensor 46 is used to detect the gas pressure in the pipeline and is connected to the connecting pipe 42. The ball valve 47 is installed on the gas delivery pipe 41 and is used to control whether the gas delivery pipe 41 is connected to the hydrogen filling port 43 and the hydrogen discharging port 44.

[0029] Furthermore, a pressure gauge 48 is also installed on the connecting pipe 42, through which the air pressure value in the pipeline can be read.

[0030] In some embodiments, the gas path assembly 4 also includes multiple automatic control valves (not shown) mounted on the gas delivery pipe 41 for remote or automatic control of whether the gas delivery pipe 41 is connected to the hydrogen filling port 43 and the hydrogen discharging port 44, thereby regulating the hydrogen storage capacity of the stackable modular solid-state hydrogen storage device. Preferably, the automatic control valves may be solenoid valves.

[0032] In some embodiments, the hydrogen storage cylinder 2 is used to store hydrogen. The hydrogen storage cylinder 2 is a columnar alloy cylinder as in the prior art, which will not be described in detail here. The hydrogen storage cylinder 2 generates a large amount of heat during hydrogen absorption and absorbs a large amount of heat during hydrogen release. The infusion tubing assembly 4 is used to supply cooled or hot liquid to the cavity 10. The cooled or hot liquid exchanges heat with multiple hydrogen storage cylinders 2 within the cavity 10, thereby cooling the hydrogen storage cylinders 2 or providing heat to them.

[0033] In some embodiments, the liquid pipe assembly 5 includes an inlet pipe 51 and an outlet pipe 52, which are respectively connected to the cavity 10. Coolant or high-temperature liquid enters the cavity 10 through the inlet pipe 51 and exits the cavity 10 through the outlet pipe 52.

[0034] Furthermore, control valves 53 are installed on both the inlet pipe 51 and the outlet pipe 52.

[0035] Understandably, hydrogen storage modules can be used individually or stacked together. When used individually, each module is equipped with a gas path assembly 4 and a liquid pipeline assembly 5. When multiple modules are stacked together, they can share a single gas path assembly 4, such as two modules, three modules, or four modules sharing the same assembly.

[0036] Furthermore, when multiple hydrogen storage modules are stacked together for use, the outlet pipe 52 of the lower hydrogen storage module in two adjacent hydrogen storage modules is connected to the inlet pipe 51 of the upper hydrogen storage module through a flexible hose.

[0037] In some embodiments, the gas path assembly 4 and the liquid pipe assembly 5 are located on opposite sides of the housing 1.

[0038] In some embodiments, the upper end of the housing 1 is provided with a plurality of anti-slip plates 12 protruding from the top of the housing 1. The plurality of anti-slip plates 12 are distributed at least on opposite edges of the housing 1. The anti-slip plates 12 are used to position and limit the hydrogen storage module located on the upper side, so that the hydrogen storage module located on the upper side can be stably placed on the hydrogen storage module below.

[0039] In some embodiments, the stackable modular solid-state hydrogen storage device also includes a base 6, on which the lowest hydrogen storage module is mounted.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
