[0014] The technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. The specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present disclosure. In addition, the relationship terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.

[0015] Please refer to Figure 1 and Figure 2 . The embodiments of the present disclosure provide a hydrogen production device.

[0016] The hydrogen production device can include an electrolytic cell 1. The electrolytic cell 1 can have a hollow structure. The electrolytic cell 1 can include a first tank body 11 and a second tank body 12. The first tank body 11 can be an inner tank body, and the second tank body 12 can be an outer tank body. The first tank body 11 is used for electrolysis reaction. A hollow cavity 13 can be formed between the first tank body 11 and the second tank body 12. The cavity 13 is used to accommodate a first heat-conducting fluid 14. The cavity 13 can be a closed cavity, or it can also be an open cavity. The first heat-conducting fluid 14 can be used as a heat exchange medium to achieve heat conduction and recycling.

[0017] The first tank body 11 and the second tank body 12 can be made of an alloy material. A high-temperature-resistant insulating material can be coated on the outer layer of the alloy material to enhance the durability and safety of the tank body and ensure that no corrosion and material fatigue occurs during long-term use.

[0018] The electrolytic tank 1 can be an alkaline electrolytic tank. The first tank body 11 can contain an electrolyte 17. The first tank body 11 is provided with a first electrode 15 and a second electrode 16. The first electrode 15 can be, for example, a cathode, and the second electrode 16 can be, for example, an anode. The first electrode 15 and the second electrode 16 can be connected to a power source. The electrolyte 17 can include a sodium hydroxide solution, a potassium hydroxide solution, or other alkaline electrolytes. The electrolytic tank 1 decomposes water into hydrogen and oxygen through the passage of current in the electrolyte 17.

[0019] On the side of the second electrode 16, water molecules are oxidized to release oxygen, electrons, and hydrogen ions. The reaction equation is:

[0020]

[0021] On the side of the first electrode 15, hydrogen ions accept electrons to be reduced to generate hydrogen gas. The reaction equation is:

[0022]

[0023] Through the above process, the electrolysis of water is achieved, generating hydrogen and oxygen.

[0024] The alkaline electrolyte has good electrical conductivity, which can effectively reduce the resistance during the electrolysis process and increase the yield of hydrogen.

[0025] The first electrode 15 and the second electrode 16 can each include a catalytic layer, a conductive layer, and a protective layer, etc. This can improve the generation rate of hydrogen and oxygen and prolong the service life of the electrodes. The use of high-efficiency catalyst coatings, such as platinum or nickel-based materials, can reduce the resistance of the electrodes, increase the reaction rate, and ensure stability at high temperatures and high pressures. Using alkaline electrolysis technology, the first electrode 15 and the second electrode 16 can not contain noble metals, making the cost of the electrolytic tank 1 relatively low.

[0026] The power source can include a wind power generation device and / or a solar power generation device. This can provide the necessary current (such as direct current) for the electrolytic tank 1 to drive the electrolysis reaction through wind power generation and / or photovoltaic power generation, achieving wind-solar hydrogen production. Wind-solar hydrogen production can utilize the electrical energy generated by wind power generation and solar power generation to convert water into hydrogen through the electrolytic tank 1. This can more effectively utilize wind energy and solar energy, optimize the energy conversion efficiency of the electrolytic tank 1, and reduce the cost of hydrogen production.

[0027] In some embodiments, electrolyte channels can be provided in the first tank 11. The electrolyte channels can comprise pipes. The number of electrolyte channels can be one or more. The electrolyte channels can be located between the first electrode 15 and the second electrode 16. In this way, during electrolysis, the electrolyte 17 can flow between the first electrode 15 and the second electrode 16 via the electrolyte channels. The electrolyte channels can have a spiral shape. In this way, the electrolyte 17 can flow in the electrolyte channels in a vortex manner, increasing the contact area between the bubbles and the electrolyte 17, thereby increasing the generation rate of hydrogen and oxygen.

[0028] Optionally, flow valves can be provided on the electrolyte channels. By adjusting the opening degree of the flow valves, the flow rate of the electrolyte 17 in the electrolyte channels can be adjusted, thereby optimizing the efficiency of the electrolysis reaction.

[0029] In some embodiments, electrolytic diaphragms can be provided in the first tank 11. The electrolytic diaphragms can be located between the first electrode 15 and the second electrode 16. The electrolytic diaphragms do not allow hydrogen molecules and oxygen molecules to pass through, thereby preventing the mixing of hydrogen and oxygen. The electrolytic diaphragms allow electrolyte ions to pass through.

[0030] In some embodiments, liquid level sensors can be provided in the first tank 11. The liquid level sensors can be provided at the bottom of the first tank 11 to detect the liquid level of the electrolyte 17 in the first tank 11. When the liquid level of the electrolyte 17 is too low, it can cause a pressure difference between the anode and the cathode, thereby causing the mixing of oxygen and hydrogen, increasing the risk of explosion. By using the liquid level sensor, the liquid level of the electrolyte 17 in the first tank 11 can be monitored.

[0031] Optionally, wind-solar hydrogen production can utilize the electrical energy generated by wind power and solar power to convert water into hydrogen through the electrolysis tank 1. In this way, wind energy and solar energy can be more effectively utilized, optimizing the energy conversion efficiency of the electrolysis tank 1 and reducing the cost of hydrogen production. However, wind and solar fluctuations can affect the stability of the electrical energy. If there is a large wind and solar fluctuation or a sudden load reduction, it can cause a large difference in liquid level between the first electrode 15 side and the second electrode 16 side, causing damage to the diaphragm and affecting the efficiency of the electrolysis process and the yield of hydrogen. Therefore, liquid level sensors can be provided on the first electrode 15 side and the second electrode 16 side respectively to detect the liquid level on the first electrode 15 side and the second electrode 16 side respectively and to quickly and timely control and adjust the liquid level to prevent the concentration of hydrogen in oxygen from exceeding the standard and causing an explosion.

[0032] In some embodiments, the first tank body 11 can be further provided with a pressure sensor and / or a temperature sensor. The pressure sensor is used to detect the pressure of the electrolyte 17. The temperature sensor is used to detect the temperature of the electrolyte 17. Through the pressure sensor and / or the temperature sensor, the temperature and / or pressure of the electrolytic tank 1 can be monitored.

[0033] In some embodiments, the first heat-conducting fluid 14 can be heat-conducting oil. The heat generated during the electrolysis process can be transmitted to the first heat-conducting fluid 14 through the first tank body 11. The heat of the first heat-conducting fluid 14 can also be transmitted to the electrolyte 17 through the first tank body 11.

[0034] In some embodiments, the hydrogen production device can further include a heat dissipation component 2. The heat dissipation component 2 can include heat dissipation fins or the like. The heat dissipation component 2 can be arranged on the surface of the second tank body 12, for example, on the side surface of the second tank body 12. The heat dissipation component 2 can reduce the heat of the first heat-conducting fluid 14 during the electrolysis process, thereby achieving timely heat dissipation during the electrolysis process.

[0035] Optionally, the input end and the output end of the heat dissipation component 2 can be connected in communication with the cavity 13 through pipelines. A first on-off valve 21 is arranged on the pipeline connected in communication with the cavity 13 at the input end. A second on-off valve 21 is arranged on the pipeline connected in communication with the cavity 13 at the output end. During the electrolysis process, the first on-off valve 21 and the second on-off valve 21 can be opened. In this way, the first heat-conducting fluid 14 can flow between the cavity 13 and the heat dissipation component 2, thereby reducing the heat of the first heat-conducting fluid 14 during the electrolysis process, and achieving timely heat dissipation during the electrolysis process.

[0036] Optionally, a first pump can also be arranged inside the cavity 13. The first pump can drive the first heat-conducting fluid 14 to circulate. For example, in the case where the first on-off valve 21 and the second on-off valve 21 are closed, the first pump can drive the first heat-conducting fluid 14 to circulate inside the cavity 13. For another example, in the case where the first on-off valve 21 and the second on-off valve 21 are opened, the first pump can drive the first heat-conducting fluid 14 to circulate between the cavity 13 and the heat dissipation component 2, thereby improving the heat dissipation efficiency.

[0037] In some embodiments, the hydrogen production device can further include a heat exchange component 3 (for example, a heat exchanger). The heat exchange component 3 can be connected in communication with the cavity 13. For example, the heat exchange component 3 can be connected in communication with the cavity 13 through a pipeline. The heat exchange component 3 is used for heat exchange between the second heat-conducting fluid and the first heat-conducting fluid 14. The second heat-conducting fluid can include heat-conducting oil or the like.

[0038] Optionally, a third switch valve 31 can be arranged on the pipeline through which the heat exchange component 3 communicates with the cavity 13. When the third switch valve 31 is opened, the first heat conducting fluid 14 can flow between the cavity 13 and the heat exchange component 3, so as to realize heat exchange between the second heat conducting fluid and the first heat conducting fluid 14.

[0039] In some embodiments, the hydrogen production device can further comprise a heating component 5. The heating component 5 can comprise an electric heater or the like. The heating component 5 can heat the second heat conducting fluid. The heating component 5 can communicate with the heat exchange component 3 through a pipeline. The second heat conducting fluid can flow between the heating component 5 and the heat exchange component 3. The heating component 5 can heat the second heat conducting fluid flowing in. The heated second heat conducting fluid output by the heating component 5 can flow into the heat exchange component 3. The heat exchange component 3 can heat the first heat conducting fluid 14 by using the second heat conducting fluid. The cooled second heat conducting fluid can flow into the heating component 5 again.

[0040] In the starting stage, the third switch valve 31 can be opened, and the first switch valve 21 and the second switch valve 21 can be closed. The heating component 5 can be started. The second heat conducting fluid can be heated by the heating component 5. The heat exchange component 3 can heat the first heat conducting fluid 14 by using the heated second heat conducting fluid. The heat of the first heat conducting fluid 14 can be transmitted to the electrolyte 17 through the first groove 11, so as to realize auxiliary heating of the electrolyte 17. Thus, the starting stage can shorten the starting time and improve the hydrogen production speed by using the heating component 5 to assist in heating the electrolyte 17. The electrolytic tank 1 does not need to be heated for a long time to reach the optimal reaction condition in the starting stage. The heating component 5 can be closed after the starting is completed. For example, the heating component 5 can be closed after the temperature of the electrolyte 17 reaches a set temperature.

[0041] The heating component 5 can have a control switch. The heating component 5 can be started and stopped by the control switch. It should be noted that starting the heating component 5 can heat the second heat conducting fluid by the heating component 5. Stopping the heating component 5 can prevent the heating component 5 from heating the second heat conducting fluid. Whether the heating component 5 is started or stopped, the heating component 5 can allow the second heat conducting fluid to flow through, i.e., the second heat conducting fluid can realize circulating flow.

[0042] Optionally, the hydrogen production device can further comprise a second pump 51. The second pump 51 can communicate with the heating component 5 and the heat exchange component 3 through a pipeline. The second pump 51 can drive the second heat conducting fluid to flow between the heating component 5 and the heat exchange component 3.

[0043] In some embodiments, the hydrogen production device can further comprise an oil-salt heat exchange component 4 (e.g., a heat exchanger), a first salt tank 6, and a second salt tank 7. The first salt tank 6 and the second salt tank 7 are configured to store molten salt. For example, the first salt tank 6 can be configured to store cold molten salt, and the second salt tank 7 can be configured to store hot molten salt. The oil-salt heat exchange component 4 can be configured to heat the second heat transfer fluid with the solution, or vice versa. With the oil-salt heat exchange component 4, the first salt tank 6, and the second salt tank 7, the heat generated during the electrolysis process can be recovered and reused. By recovering and reusing the heat generated during the electrolysis process, the energy efficiency can be significantly improved, and the operating cost can be reduced.

[0044] In some embodiments, the heat generated during the electrolysis process can be transferred from the first tank 11 to the first heat transfer fluid 14 in the cavity 13. The heat exchange component 3 can be configured to heat the second heat transfer fluid with the first heat transfer fluid 14. The oil-salt heat exchange component 4 can be configured to heat the molten salt in the first salt tank 6 with the heated second heat transfer fluid. The heated molten salt can be stored in the second salt tank 7. In this way, the heat generated during the electrolysis process can be recovered.

[0045] Optionally, the hydrogen production device can further comprise a first salt pump 61. The first salt pump 61 is in communication with the first salt tank 6 and the oil-salt heat exchange component 4. The first salt pump 61 can be configured to pump the molten salt in the first salt tank 6 into the oil-salt heat exchange component 4, so that the oil-salt heat exchange component 4 can heat the molten salt with the second heat transfer fluid. The heated molten salt can be stored in the second salt tank 7.

[0046] Optionally, during the electrolysis process, the third switch valve 31 can be opened, the first switch valve 21 and the second switch valve 21 can be closed, and the heating component 5 can be turned off. The first pump can be configured to drive the first heat transfer fluid 14 to circulate between the cavity 13 and the heat exchange component 3. The second pump 51 can be configured to drive the second heat transfer fluid to circulate among the heating component 5, the heat exchange component 3, and the oil-salt heat exchange component 4. The first salt pump 61 can be configured to drive the molten salt in the first salt tank 6 to enter the oil-salt heat exchange component 4 and then enter the second salt tank 7. In this way, the heat generated during the electrolysis process can be transferred from the first tank 11 to the first heat transfer fluid 14 in the cavity 13. The heat exchange component 3 can be configured to heat the second heat transfer fluid with the first heat transfer fluid 14. The oil-salt heat exchange component 4 can be configured to heat the molten salt with the heated second heat transfer fluid. The heated molten salt can be stored in the second salt tank 7. In this way, the heat generated during the electrolysis process can be recovered.

[0047] Of course, during the electrolysis process, the third switch valve 31 can be opened, and the first switch valve 21 and the second switch valve 21 can be opened. In this way, during the electrolysis process, the first heat-conducting fluid 14 can flow into the heat-dissipating component 2, reducing the heat of the first heat-conducting fluid 14 during the electrolysis process, and achieving timely heat dissipation during the electrolysis process. Moreover, the heat generated during the electrolysis process can also be recovered.

[0048] In some embodiments, during the starting stage, the oil-salt heat exchange component 4 can use the molten salt in the second salt tank 7 to heat the second heat-conducting fluid. The cooled molten salt can be stored in the first salt tank 6. The heat exchange component 3 can use the second heat-conducting fluid to heat the first heat-conducting fluid 14. The heat of the first heat-conducting fluid 14 can be transferred to the electrolyte 17 through the first tank body 11. Thus, by using the recovered heat to assist in heating the electrolyte 17 during the starting stage, the starting time can be shortened, and the hydrogen production speed can be improved. The electrolytic tank 1 does not need to be heated for a long time during the starting stage to reach the optimal reaction conditions.

[0049] Optionally, the hydrogen production device can further include a second salt pump 71. The second salt pump 71 is in communication with the second salt tank 7 and the oil-salt heat exchange component 4. The second salt pump 71 can pump the molten salt in the second salt tank 7 into the oil-salt heat exchange component 4, so that the oil-salt heat exchange component 4 uses the hot molten salt to heat the second heat-conducting fluid. The cooled molten salt can be stored in the first salt tank 6.

[0050] Optionally, during the starting stage, the third switch valve 31 can be opened, and the first switch valve 21 and the second switch valve 21 can be closed. The heating component 5 can be closed. The first pump can drive the first heat-conducting fluid 14 to circulate between the cavity 13 and the heat exchange component 3. The second pump 51 can drive the second heat-conducting fluid to circulate among the heating component 5, the heat exchange component 3, and the oil-salt heat exchange component 4. The second salt pump 71 can drive the molten salt in the second salt tank 7 to enter the oil-salt heat exchange component 4 and then enter the first salt tank 6. Thus, during the starting stage, the oil-salt heat exchange component 4 can use the molten salt in the second salt tank 7 to heat the second heat-conducting fluid. The heat exchange component 3 can use the second heat-conducting fluid to heat the first heat-conducting fluid 14. The heat of the first heat-conducting fluid 14 can be transferred to the electrolyte 17 through the first tank body 11.

[0051] Of course, during the starting stage, the heating component 5 can also be opened. In this way, the heating component 5 and the recovered heat can be used to assist in heating the electrolyte 17 at the same time, so that the starting time can be further shortened, and the hydrogen production speed can be improved.

[0052] After the starting stage ends, the second pump 51 can be closed. Optionally, after the starting stage ends, the first pump can also be opened, so that the heat generated during the electrolysis process can be recovered. The specific recovery process is not described here again.

[0053] In some embodiments, the hydrogen production device can further comprise a gas separation component. The gas separation component can effectively separate gas from liquid.

The oxygen separation component can be disposed on the side of the second electrode 16. Oxygen gas entraining electrolyte 17 can enter the oxygen separation component. The oxygen separation component can separate oxygen gas from electrolyte 17 and output oxygen gas.

[0054] In some embodiments, the hydrogen production device can further comprise a first gas storage tank and a second gas storage tank. The first gas storage tank can be connected to the hydrogen separation component through a pipeline. Hydrogen gas output by the hydrogen separation component can be stored in the first gas storage tank.

The computer device can comprise a server or a terminal device such as a smartphone. The computer device can receive and display data detected by one or more of the liquid level sensor, the temperature sensor, the pressure sensor, the voltage sensor, and the current sensor. In this way, a user can view the liquid level, temperature, pressure, voltage, and current of the hydrogen production device through the computer device, thereby achieving monitoring of the liquid level, temperature, pressure, voltage, and current of the hydrogen production device.

[0059] The computer device can further issue an alarm when one or more of the liquid level, temperature, pressure, voltage, and current exceeds a set range, reminding the user to take countermeasures. In this way, the safety of the hydrogen production device is improved.
