[0002] Solid hydrogen storage technology refers to the technology of using solid materials (such as metal hydrides, compounds or other synthetic materials) to adsorb and release hydrogen. Hydrogen is mainly adsorbed or combined in solid materials through physical or chemical means. Compared with traditional gaseous or liquid hydrogen storage methods, this hydrogen storage method has high safety, large hydrogen storage capacity, mild hydrogen storage conditions, and the solid hydrogen storage material can be recycled. Solid hydrogen storage devices are applied in fields such as hydrogen fuel cells, hydrogen energy vehicles, and renewable energy storage.

[0003] In order to release the hydrogen in the solid material of the solid hydrogen storage device, high-temperature liquid is usually used to heat the hydrogen storage cylinder, so that the solid material is heated and the stored hydrogen is released. However, when the high-temperature liquid is input between the hydrogen storage cylinder and the outer cylinder, the connection between the hydrogen storage cylinder and the outer cylinder is prone to leakage of the high-temperature liquid, resulting in a dirty and messy use environment and being not conducive to the recycling of the high-temperature liquid. Content of the Utility Model

[0026] In view of the problems existing in the above related technologies, this embodiment provides a solid-state hydrogen storage device for experiments.

[0027] As Figure 1 shown, a solid-state hydrogen storage device for experiments provided by an embodiment of the present utility model includes a support frame 1, an inner cylinder 2, an outer cylinder 3, a flange, a first gasket 5 and a sealing ring 8. As Figure 1 and Figure 2 shown, the outer cylinder 3, the flange and the inner cylinder 2 are placed on the support frame 1, the outer cylinder 3 and the flange are sleeved on the inner cylinder 2, and the two flanges are installed at both ends of the outer cylinder 3. As Figure 3 shown, the sealing ring 8 and the first gasket 5 are sleeved on the inner cylinder 2, the first gasket 5 is arranged between the flange and the outer cylinder 3, an annular accommodation groove is arranged on the inner surface of the flange in contact with the inner cylinder 2, the sealing ring 8 is installed in the annular accommodation groove, and a liquid inlet 6 and a liquid outlet 7 are arranged on the outer cylinder 3.

[0028] Specifically, as Figure 3 described, the outer cylinder 3, the flange and the inner cylinder 2 are placed on the support frame 1. The support frame 1 is used to limit the positional relationship between the outer cylinder 3 and the inner cylinder 2, so that there is no relative movement between the inner cylinder 2 and the outer cylinder 3 in the axial direction. At the same time, a clamping groove is arranged on the support frame 1 for supporting the flange and the outer cylinder 3.

[0029] In this embodiment, the liquid for cyclic heating is injected from the liquid inlet 6 into the liquid storage cavity 16 between the outer cylinder 3 and the inner cylinder 2. The high-temperature liquid wraps the inner cylinder 2 to heat the inner cylinder 2. The solid material in the inner cylinder 2 releases hydrogen when heated. The gradually cooled liquid is discharged from the liquid outlet 7, and then the heated liquid is continuously injected from the liquid inlet 6 to ensure the liquid temperature in the liquid storage cavity 16. Flange plates are installed at both ends of the outer cylinder 3. A sealing ring 8 is arranged between the flange plate and the inner cylinder 2, and a first gasket 5 is arranged between the flange plate and the outer cylinder 3, so that the connection between the inner cylinder 2 and the outer cylinder 3 is sealed. Moreover, after the heated liquid is injected into the liquid storage cavity 16, the temperatures of the flange plate, the outer cylinder 3 and the inner cylinder 2 all increase, so that the temperatures of the sealing ring 8 and the first gasket 5 increase. The sealing ring 8 and the first gasket 5 expand when heated, improving the sealing effect. The liquid in the liquid storage cavity 16 is not likely to leak, maintaining the laboratory environment clean, and the liquid in the liquid storage cavity 16 will not be wasted and can be recycled.

The gas transmission pipe 12 transports the hydrogen to the inside of the inner cylinder 2. Under appropriate temperature and pressure, the hydrogen is adsorbed by the solid material, thus completing the solid-state storage of hydrogen. The inlet filter 10 filters the incoming hydrogen to prevent other solid impurities in the hydrogen from entering the inner cylinder 2.

[0034] Optionally, the experimental solid-state hydrogen storage device further includes a second gasket 9, which is installed in the groove on the end cap 13, and the second gasket 9 is located between the end cap 13 and the inlet filter 10.

[0035] In this embodiment, when the end cap 13 is installed on one end of the inner cylinder 2, the end cap 13 presses the second gasket 9 and the inlet filter 10 in the groove on the end cap 13. The second gasket 9 reduces the installation pressure on the inlet filter 10, avoids damage to the inlet filter 10, and can also seal the connection between the air inlet 11 and the gas transmission pipe 12 to prevent hydrogen leakage.
