[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0028] Secondly, it should be noted that in the description of the present application, terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0029] In order to solve the above technical problems, Figure 1-3As shown, an embodiment of the present application provides a novel solid-state hydrogen production system, comprising a hydrogen storage material box 1 and an instant hydrogen production device 2, a gas-liquid separator 3, a peristaltic pump 4, and a gas flow meter 5 located in the hydrogen storage material box 1, wherein the hydrogen storage material box 1 is made of six-sided support bars to form a rectangular box structure, the instant hydrogen production device 2 is located on the inner bottom plate of the hydrogen storage material box 1, the gas-liquid separator 3 and the peristaltic pump 4 are located next to the instant hydrogen production device 2, and the gas-liquid separator 3 is arranged along a direction perpendicular to the lateral direction of the instant hydrogen production device 2.

[0030] In some specific embodiments, the instant hydrogen production device 2 has an inlet 21 and an outlet 22. The inlet 21 of the instant hydrogen production device 2 is located at its upper end, and the inlet 21 is used to introduce sodium borohydride solution when producing hydrogen. The outlet 22 of the instant hydrogen production device 2 is located at its lower end, and the outlet 22 is connected to the peristaltic pump 4 through a pipeline. The peristaltic pump 4 is connected to the inlet of the gas-liquid separator 3 through a pipeline. The gas-liquid separator 3 has a liquid outlet and a gas outlet. The liquid outlet of the gas-liquid separator 3 is connected back to the instant hydrogen production device 2, and a gas flowmeter 5 is provided on the gas outlet channel of the gas-liquid separator 3.

[0031] More specifically, the instant hydrogen production device 2 includes a plurality of stacked reaction tanks 23, which are arranged horizontally along the hydrogen production material box and fixed at both ends by a fixing plate 24, and each adjacent section of the reaction tank 23 and between the reaction tank 23 and the fixing plate 24 are fixed by a clamping nut. In this embodiment, the reaction tank 23 is preferably five-section, and is made of metal material, such as stainless steel. A metal film catalyst layer is sandwiched in each section of the reaction tank 23. When the sodium borohydride solution is introduced into the inlet 21 of the instant hydrogen production device 2, the sodium borohydride solution passes through the reaction tank 23 in turn and contacts the metal film catalyst layer in the reaction tank 23 to catalyze hydrogen production. Among them, the catalyst of the metal film catalyst layer is a cobalt-nickel bimetallic catalyst.

[0032] Exemplarily, the hydrogen storage material box 1 is made of high-strength plastic, the instant hydrogen production device 2 is made of alloy material, and the gas-liquid separator 3 is made of high-light plastic.

[0033] Exemplarily, the model of the peristaltic pump 4 is PU-SC1000, and the peristaltic pump 4 is provided with a branch pipe (not shown in the figure), and the branch pipe is used to control the reaction speed.

[0034] Exemplarily, the model of the gas-liquid separator 3 is AL3000-03.

[0035] The specific implementation principle of the solid-state hydrogen production system in the embodiment of the present application is:

[0036] First, after injecting sodium borohydride solution into the inlet 21 of the instant hydrogen production device 2, it is pumped into the instant hydrogen production device 2 through the peristaltic pump 4. The metal film catalyst inside the instant hydrogen production device 2 is fully in contact with the sodium borohydride solution to catalyze hydrogen production. Finally, the solution and hydrogen enter the gas-liquid separator 3 at the same time for gas-liquid separation. The liquid re-enters the system circulation, and the hydrogen leaves the system through the gas flow meter 5.

[0037] The solid-state hydrogen production system of the embodiment of the present application also includes a control system, such as a PLC control system, which is used to control the electrical properties of various electrical devices in the system of the embodiment, such as the instant hydrogen production device 2, the gas-liquid separator 3, the peristaltic pump 4, and the gas flow meter 5, so as to realize the automatic operation of the system. It should also be noted that the PLC control system is a prior art and will not be described in detail here.

[0038] The novel solid-state hydrogen production system of the embodiment of the present application is suitable for the use of hydrogen in the fields of drones, two-wheeled hydrogen electric vehicles, etc. The system is loaded as a whole on a hydrogen electric vehicle to provide hydrogen energy for the hydrogen electric vehicle. Compared with traditional hydrogen storage tanks, the cost is only one-third of that of hydrogen storage tanks under the same driving time, which greatly reduces the cost of use.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
