[0028] Refer to the following Figure 1 A solid-state hydrogen storage device according to some embodiments of the present application is described.

[0029] See also Figure 1 As shown, an embodiment of the present application provides a solid-state hydrogen storage device, comprising: a solid-state hydrogen storage tank 1 and a heating component 2; wherein, the solid-state hydrogen storage tank 1 is used to store fixed hydrogen storage materials, and the heating component 2 is arranged on the outside of the solid-state hydrogen storage tank 1, and is used to heat the solid-state hydrogen storage material in the solid-state hydrogen storage tank 1 so that it forms a molten state and can flow out of the solid-state hydrogen storage tank 1.

[0030] According to the structure described above, when the solid-state hydrogen storage material in the solid-state hydrogen storage device provided by the present application needs to be taken out, the heating component 2 can be used to heat the solid-state hydrogen storage material in the solid-state hydrogen storage tank 1 to convert it into a liquid state, thereby facilitating its discharge from the solid-state hydrogen storage tank 1. It can be seen that the solid-state hydrogen storage material in the solid-state hydrogen storage device provided by the present application is easy to recycle and reuse, thereby improving the efficiency and sustainability of the hydrogen storage system and having broad application prospects.

[0031] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage tank 1 is formed with an installation cavity and a recovery port 11 connected to the installation cavity, and the recovery port 11 can be opened or closed. The installation cavity is used to store solid-state hydrogen storage materials, and when the heating component 2 heats the solid-state hydrogen storage material in the installation cavity into a molten state, the molten solid-state hydrogen storage material can flow out of the installation cavity to the outside through the recovery port 11.

[0032] According to the structure described above, a recovery port 11 can be provided separately, through which the molten solid hydrogen storage material is discharged from the installation cavity, thereby realizing the recovery and reuse of the solid hydrogen storage material.

[0033] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage tank 1 is arranged in a vertical direction, and the recovery port 11 is formed at the bottom of the solid-state hydrogen storage tank 1 .

[0034] According to the structure described above, it can be seen that, in particular, the recovery port 11 is set at the bottom of the solid-state hydrogen storage tank 1, and the molten solid-state hydrogen storage material can be automatically discharged under the action of gravity without the need to turn the solid-state hydrogen storage tank 1 over, thereby improving the convenience of operation, saving time and effort, and improving work efficiency. Moreover, the recovery port 11 is set at the bottom of the solid-state hydrogen storage tank 1, so that the solid-state hydrogen storage material at the bottom can also be completely discharged, and other structures in the solid-state hydrogen storage tank 1, such as the thermal oil heating structure, can be avoided.

[0035] Furthermore, preferably, the device further comprises a recovery pipe, which is installed at the recovery port 11 , and the valve 3 described below is installed on the recovery pipe, and the material of the recovery pipe is a high-temperature resistant material.

[0036] It should be noted that the recovery port 11 is not limited to being formed at the bottom of the solid-state hydrogen storage tank 1, but can also be set at other positions. For example, the recovery port 11 can also be formed at the side of the solid-state hydrogen storage tank 1, and it can extend all the way to the installation cavity inside the solid-state hydrogen storage tank 1, or the recovery port 11 can be set at the top of the solid-state hydrogen storage tank 1, etc. Of course, it is not limited to this, and the recovery port 11 can also be not set, and the molten solid-state hydrogen storage material can be directly discharged by using the filling port of the original solid-state gas storage tank.

[0037] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage device further includes a valve 3 , and the valve 3 is installed at the recovery port 11 .

[0038] According to the structure described above, it can be seen that the valve 3 is provided at the recovery port 11, so as to facilitate opening or closing of the recovery port 11 and improve the convenience of operation.

[0039] It should be noted that: the valve 3 may not be provided, but a sealing plug or a sealing cover may be provided and installed at the recovery port 11, thereby also realizing the operation of opening or closing the recovery port 11.

[0040] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage device further includes a thermal insulation layer 4 , and the thermal insulation layer 4 covers the outside of the solid-state hydrogen storage tank 1 and the heating component 2 .

[0041] According to the structure described above, when the solid hydrogen storage material in the solid hydrogen storage tank 1 is heated by the heating component 2, the thermal insulation layer 4 plays a role in heat preservation, thereby improving the heating efficiency.

[0042] Furthermore, preferably, the thermal insulation layer 4 can be fixed to the outer wall of the heating component 2 and the solid-state hydrogen storage tank 1 by gluing or the like. Of course, this is not limited to the above. The thermal insulation layer 4 can also be fixed to the heating component 2 and the solid-state hydrogen storage tank 1 by external bundling.

[0043] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage device further includes a first temperature detection component 5 , which is installed on the solid-state hydrogen storage tank 1 and is used to detect the temperature of the heating component 2 .

[0044] According to the above-described structure, the temperature of the heating member 2 can be detected by the first temperature detecting member 5 .

[0045] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage device further includes a second temperature detection component 6 , which is installed on the solid-state hydrogen storage tank 1 and is used to detect the temperature of the solid-state hydrogen storage material in the solid-state hydrogen storage tank 1 .

[0046] According to the structure described above, it can be seen that the second temperature detection member 6 can be used to detect the temperature of the hydrogen storage material in the solid-state hydrogen storage tank 1 .

[0047] In this embodiment, preferably, Figure 1 As shown, the solid-state hydrogen storage device further includes a power supply 7 and a bus 8 , and the heating component 2 is connected to the power supply 7 via the bus 8 .

[0048] According to the structure described above, the heating component 2 is connected to the power supply 7 via the bus 8, and the power supply 7 supplies power to the heating component 2 to enable it to operate.

[0049] In this embodiment, preferably, Figure 1 As shown, the first temperature detection component 5 and the second temperature detection component 6 are both temperature sensors. The solid-state hydrogen storage device also includes a controller, and the controller is communicatively connected to the power supply 7, the first temperature detection component 5, and the second temperature detection component 6 respectively.

[0050] According to the structure described above, the power supply 7 may include a power distribution system, which is responsible for distributing the power supply 7 to controllers such as a PLC controller and a medium frequency power generator. The PLC controller is used to automatically control the process. The PLC collects data from the internal temperature of the hydrogen storage tank and the temperature during electromagnetic induction heating, as well as the flow rate and valve 3 signal, and controls the entire heating process through calculation and logical operations; the medium frequency power generator receives instructions from the PLC controller, generates a device for generating alternating current of a specific frequency according to control requirements, and generates a power supply 7 suitable for electromagnetic induction heating; the current generated by the medium frequency power generator passes through a heating component 2, such as the electromagnetic induction coil described below, to generate an alternating magnetic field, thereby heating the solid hydrogen storage material.

[0051] Among them, temperature, flow, and valve 3 signals: These signals are collected from different points in the heating process, such as measuring the temperature of the hydrogen storage material, the flow rate through the system, and controlling the status of valve 3. These signals are collected by the PLC controller so that the PLC can adjust the heating process according to the current conditions. It can be seen that the working principle of the entire system is closed-loop control, which means that the PLC controller continuously collects feedback signals from the heating process and then adjusts the output of the medium-frequency power generator based on these signals to maintain ideal heating conditions. This system design helps to achieve precise temperature control and efficient energy transmission, ensuring that the solid-state hydrogen storage material will not be affected by overheating or insufficient heating during the heating process. In addition, through the control of the PLC controller, automated operation and remote monitoring can also be achieved, improving production efficiency and safety.

[0052] In this embodiment, preferably, Figure 1 As shown, the heating component 2 is spirally shaped and spirals along the outer circumference of the solid hydrogen storage tank 1 .

[0053] According to the structure described above, the heating component 2 is spiraled around the outer periphery of the solid-state hydrogen storage tank 1, covering a wide area and being evenly distributed, thereby improving the heating efficiency and uniformity of heating. Moreover, this structure can change the pitch according to actual needs, that is, the distance between two adjacent sections of the heating components 2, to meet different heating requirements.

[0054] It should be noted that the shape and distribution of the heating component 2 are not limited to the above, and other forms can also be adopted. For example, the heating component 2 is arranged in a continuous bending shape to form a flat heating structure, and is arranged on the side of the solid-state hydrogen storage tank 1. It is particularly suitable for flat or square hydrogen storage tanks. The flat heating structure can fit the surface of the hydrogen storage tank to achieve local or full heating.

[0055] In this embodiment, preferably, Figure 1 As shown, the heating component 2 is an electromagnetic induction heating element.

[0056] According to the structure described above, the power supply 7 provides an alternating current to the electromagnetic induction heating element to generate an electromagnetic field to heat the solid hydrogen storage material in the solid hydrogen storage tank 1. Moreover, electromagnetic induction heating can directly generate heat inside the solid hydrogen storage material, reducing the loss during heat transfer and improving the heating efficiency. Moreover, by rationally designing the electromagnetic induction coil, uniform heating of the solid hydrogen storage material can be achieved to avoid local overheating. Moreover, the electromagnetic induction heating system can accurately control the heating process by adjusting the frequency and power of the power supply 7 to achieve automated operation. Moreover, electromagnetic induction heating does not produce harmful gases or waste, meets environmental protection requirements, and reduces safety hazards such as fire.

[0057] During the heating process, in order to ensure that the solid-state hydrogen storage material is heated to the melting point and maintains a stable heating state, it is usually necessary to combine the aforementioned first temperature detection component 5 and the second temperature detection component 6 and the feedback control system. The second temperature detection component 6 can monitor the temperature changes of the solid-state hydrogen storage material in real time. The feedback control system automatically adjusts the frequency and power of the electromagnetic field according to the sensor data to achieve precise heating control. This closed-loop control method can effectively compensate for heating deviations caused by environmental changes or changes in material properties, ensuring that the heating process of the material near its melting point is stable and reliable.

[0058] Furthermore, different solid-state hydrogen storage materials have different electromagnetic properties and melting points, which affect the efficiency of electromagnetic field heating. A detailed analysis of the material's properties allows for the selection of appropriate electromagnetic field frequency and power settings to ensure an optimized heating process. This requires in-depth research into the material's electromagnetic wave absorption characteristics, thermal conductivity, and melting point to achieve the most efficient heating process.

[0059] It can be seen that the electromagnetic induction heating device can be flexibly configured according to different hydrogen storage materials and application scenarios, and can adapt to the hydrogen storage needs in various scenarios. Using electromagnetic induction heating to heat the hydrogen storage material to the melting point and flow it out through the recovery port is a complex process involving precise temperature control, flow design and efficient collection. Through reasonable design and optimization of each link, efficient recovery of hydrogen storage materials can be achieved, thereby improving material utilization efficiency and reducing production costs.

[0060] It should be noted that the heating method of the heating component 2 is not only electromagnetic induction heating, but also other heating types, for example, it can also be a heating structure such as a heating tube.

[0061] In this embodiment, preferably, Figure 1 As shown, the heating component 2 is connected to the solid-state hydrogen storage tank 1 to fix the heating component 2. Preferably, the heating component 2 and the solid-state hydrogen storage tank 1 can be connected by welding, gluing or bolts.

[0062] According to the structure described above, the heating component 2 is connected to the solid-state hydrogen storage tank 1 so that the heating component 2 will not shift, thereby ensuring the heating effect.

[0063] 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 them. 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 make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
