[0018] The utility model will be further described in detail below by specific embodiment and in combination with the drawings. Embodiment 1

[0019] AsFigure 1 and Figure 2 As shown in FIG. 1, a portable solid-state hydrogen storage system includes a needle-type solid-state hydrogen storage bottle 1 and a needle-type stop valve 2. The needle-type solid-state hydrogen storage bottle 1 includes a bottle body, an end of which is provided with a normally closed needle 101 and an externally threaded joint 102. The needle-type stop valve 2 includes a needle 201, an internally threaded joint 202, a filter screen passage 203, a stop valve adjusting handle 204, and a stop valve core 205. The internally threaded joint 202 is arranged at an end of the needle-type stop valve 2, and the needle 201 is mounted inside the internally threaded joint 202.

[0020] In this embodiment, the needle-type solid-state hydrogen storage bottle 1 can be used alone to store hydrogen.

[0021] In this embodiment, as shown in FIG. 2, the normally closed needle 101 includes a plug structure at the hydrogen storage bottle port and a needle body structure inside the externally threaded joint 102. When the passage needs to be opened, the needle body structure is only needed to be pressed inward to drive the plug structure to loosen, and the normally closed needle 101 is normally in a closed state. Figure 1 In this embodiment, the end of the needle body structure is a certain distance away from the outer port of the externally threaded joint 102, which matches the length of the needle 201. Specifically, the length of the needle 201 is slightly longer than the distance, so that when the externally threaded joint 102 of the solid-state hydrogen storage bottle 1 and the internally threaded joint 201 of the matched needle-type stop valve 2 are screwed, the normally closed needle 101 in the solid-state hydrogen storage bottle 1 and the needle 201 in the matched needle-type stop valve 2 just contact, the normally closed needle 101 is opened, and the functions of hydrogen charging and discharging can be realized.

[0022] In this embodiment, as shown in FIG. 3, the filter screen passage 203 is located between the internally threaded joint 202 and the stop valve core 205. Specifically, the filter screen passage 203 is in communication with the internally threaded joint 202 and the stop valve core 205. The filter screen passage 203 added in the needle-type stop valve 2 can realize the free entry and exit of hydrogen, and can further filter out the solid-state hydrogen powder, so as to ensure the purity of hydrogen and prevent the powder from entering the subsequent pipeline or fuel cell, thereby increasing the service life and safety of the overall system.

[0023] Figure 2 In this embodiment, as shown in FIG. 4, the stop valve adjusting handle 204 is connected with the stop valve core 205 to control the on-off of the pipeline. This structure integrates the needle to ensure compact structure, reduce cost, and reduce the risk of leakage due to fewer connection points.

[0024] In this embodiment, as shown in FIG. 5, the stop valve adjusting handle 204 is connected with the stop valve core 205 to control the on-off of the pipeline. This structure integrates the needle to ensure compact structure, reduce cost, and reduce the risk of leakage due to fewer connection points. Figure 2
