[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] A portable integrated hydrogen generation and storage device, such as Figures 1 to 3 As shown, the device includes: a box body 1, a box cover 2, a solar panel 3, an exhaust cover 5, a controller 7, a photocatalyst box 8, a first solenoid valve 9, an anode electrode 10, a solid hydrogen storage plate 11, a collection tank 12, a concentration sensor 13, a guide plate 14, a gas pipe 15, a stirring rod 16, an air pressure sensor 17, an electrolytic cell 18, a thermocouple plate 19, a cathode electrode 20, a purification tank 21, a deoxidizer plate 22, a molecular sieve 23, a second solenoid valve 24 and a battery 25.

[0028] The box cover 2 is hinged to the top of the box body 1. The box cover 2 is made of a light-transmitting material, a sealing layer is bonded to the bottom of the box cover 2, and a plurality of solar panels 3 are embedded in the box cover 2 at intervals. The sealing layer can effectively fill the small gap between the box cover and the box body, prevent gas leakage, and improve the safety of the storage and transportation process. The light-transmitting material of the box cover 2 is a polycarbonate plate, which has excellent light transmittance and impact resistance.

[0029] An exhaust cover 5 is hinged on one side wall of the box body 1 to facilitate replacement of a solid hydrogen storage plate filled with hydrogen. Several partitions are welded to the inner bottom wall of the box body 1, and the partitions divide the interior of the box body into an electrolytic cell 18, a purification tank 21, and a collecting tank 12. The electrolytic cell 18 and the purification tank 21 are both located below the box cover 2, and the collecting tank 12 is arranged on the outer wall of the electrolytic cell 18 near the exhaust cover 5. The bottom of the solar panel 3 is bolted to a photocatalyst box 8, and the photocatalyst box 8 is opposite to the top of the electrolytic cell 18. A photocatalyst is placed in the photocatalyst box 8, and the electric small box door of the photocatalyst box 8 can be powered by the power generated by the solar panel 3.

[0030] The inner side walls on both sides of the electrolytic cell 18 are respectively fixedly connected with a positive electrode 10 and a negative electrode 20 by bolts. The partition used to separate the electrolytic cell 18 and the purification tank 21 is connected with a first electromagnetic valve 9, and the electrolytic cell 18 is connected with the purification tank 21 through the first electromagnetic valve 9. The inner bottom wall of the electrolytic cell 18 can be fixedly connected with a plurality of motors by bolts, and the output shafts of the motors are fixedly connected with stirring rods 16. The stirring rods continuously stir the water body during the electrolysis process, so that the electrolyte in the water is more evenly distributed, and the concentration gradient effect during the electrolysis process is reduced, which helps to increase the contact area between the electrode and the water body, improve the speed and efficiency of the electrolysis reaction, and thus accelerate the generation rate of hydrogen.

[0031] A number of molecular sieves 23 are fixedly connected to the inner wall of the purification tank 21 by bolts, which function as a filter, and the gas flows irregularly inside. A battery installation slot is separated by a partition in the purification tank 21, and a battery 25 is fixedly connected to the inner wall of the battery installation slot by bolts, and the solar panel 3 is electrically connected to the battery 25. A second solenoid valve 24 is connected to an inner wall of the purification tank 21 away from the battery 25. The second solenoid valve 24 is connected to the collection tank 12 through a gas pipe 15. The gas pipe 15 is connected to a guide plate 14, which is fixedly connected to the inner wall of the collection tank 12 by bolts. The guide plate helps the hydrogen to be evenly distributed in the collection tank to reduce the aggregation and escape of bubbles.

[0032] The molecular sieve 23 is based on Ce 3+ Ion exchange molecular sieve, Ce 3+ Ion exchange molecular sieves rely on Ce 3+ The strong electric field formed by the distribution in the molecular sieve can enhance the adsorption capacity of the molecular sieve 23 for oxygen molecules, thereby enhancing the oxygen adsorption performance.

[0033] The inner walls of the electrolytic cell 18 and the purification cell 21 are both fixedly connected with an air pressure sensor 17 and a concentration sensor 13 by bolts.

[0034] A plurality of solid hydrogen storage plates 11 are fixedly connected to the inner wall of the collecting tank 12 by bolts, and concentration sensors 13 are also fixedly connected between adjacent solid hydrogen storage plates 11 by bolts. By arranging concentration sensors between adjacent solid hydrogen storage plates, the concentration of hydrogen in the storage space can be monitored, which helps to ensure that the stored hydrogen reaches a predetermined purity standard. The solid hydrogen storage plate 11 is made of an alloy material that can react with hydrogen to produce metal hydride. The solid hydrogen storage plate can absorb and store hydrogen to achieve long-term storage of hydrogen.

[0035] The top of the box body 1 is fixedly connected with a controller 7 by bolts. The controller 7 is used to adjust the operating parameters of the positive electrode 10, the negative electrode 20, the first solenoid valve 9, the motor of the stirring rod 16, the second solenoid valve 24 and the photocatalyst box 8 and receive data from the air pressure sensor 17 and the concentration sensor 13. The controller can automatically adjust the operating parameters of the electrolyzer and the purification tank, such as current density, electrolyte flow rate, photocatalyst dosage, etc., according to the data fed back by the air pressure sensor and the concentration sensor, to optimize the hydrogen production process. This intelligent control strategy helps to improve the efficiency of hydrogen production and reduce energy consumption and cost.

[0036] The method of using the portable integrated hydrogen generation and storage device of the present invention is as follows:

[0037] First, the user opens the box cover 2 and injects water or other electrolyte solution into the electrolytic cell 18, and ensures that the positive electrode 10 and the negative electrode 20 are immersed in the solution. Close the box cover 2, adjust the device to a position where sunlight is irradiated, so that the solar panel 3 is fully exposed to the sunlight, and start to supply power to the entire device. Part of the electricity generated by the solar panel 3 is directly supplied to the electrolysis process in the electrolytic cell 18, and the other part is stored in the storage battery 25, realizing multiple utilization of energy.

[0038] The controller 7 starts the water electrolysis process by energizing the anode electrode 10 and the cathode electrode 20 in the electrolytic cell 18. The motor drives the stirring rod 16 to continuously stir the solution during the electrolysis process to ensure uniform electrolysis efficiency. Hydrogen and oxygen are generated in the electrolyte solution through the anode electrode 10 and the cathode electrode 20.

[0039] At the same time, the power generated by the solar panel 3 is stored in the storage battery 25. The controller 7 determines that the environment has the light conditions required by the photocatalyst at this time, drives the door of the photocatalyst box 8 to open, and the photocatalyst falls into the electrolytic cell 18 and contacts with water or other electrolyte solutions. Sunlight penetrates the box cover 2 made of light-transmitting material to reach the electrolytic cell 18, and the photocatalyst (such as titanium dioxide, zinc oxide ZnO, cadmium sulfide or copper oxide, etc.) decomposes water into hydrogen and oxygen under light conditions.

[0040] The above electrolysis process and photocatalyst hydrolysis process combine the advantages of solar energy and photocatalysts, and have higher energy efficiency and environmental protection. Photocatalysts can also further promote the efficiency of electrolysis reaction and purification effect.

[0041] When the hydrogen concentration and pressure in the electrolytic cell 18 reach the preset value, the first solenoid valve 9 automatically opens to allow hydrogen to enter the purification tank 21. After the hydrogen enters the purification tank 21, the impurity gas carried is filtered out by the molecular sieve 23, and the impurity gas includes oxygen and water vapor. The air pressure sensor 17 and the concentration sensor 13 in the purification tank 21 monitor the pressure and purity of the hydrogen in real time. When the purity and pressure of the hydrogen in the purification tank 21 reach the preset value, the second solenoid valve 24 automatically opens to allow hydrogen to enter the collection tank 12.

[0042] The hydrogen enters the collecting tank 12 through the gas pipe 15 and the guide plate 14 in turn. The guide plate 14 receives the gas from the gas pipe 15, and after rectifying the gas, allows the gas to evenly and fully contact and react with the solid hydrogen storage plate 11 over a large area, and evenly distributes the gas between the solid hydrogen storage plates 11. When the solid hydrogen storage plate 11 contacts the hydrogen, the hydrogen reacts chemically with the alloy material, and the hydrogen atoms are attracted to the metal voids to form metal hydrides to achieve the storage purpose. This hydrogen storage method is not only safe and stable, but also has a high hydrogen storage density and is easy to transport and carry.

[0043] The concentration sensor 13 between adjacent solid hydrogen storage plates 11 monitors the concentration change during the hydrogen storage process to ensure storage efficiency and safety. The controller 7 continuously monitors the operating status of the entire system, including various parameters of the electrolytic cell 18 (electrolysis speed), the purification cell 21 (gas pressure and concentration) and the collection cell 12 (efficiency of collecting hydrogen). Once an abnormality is found, the controller 7 will automatically adjust the operating parameters or issue an alarm prompt, including excessive pressure and substandard hydrogen concentration.

[0044] Example 2

[0045] It is basically the same as the above-mentioned embodiment 1, except that: the inner walls of the two width directions of the electrolytic cell 18 are fixedly connected with thermocouple plates 19 by bolts, and the thermocouple plates 19 are close to the opposite surfaces of the positive electrode 10 and the negative electrode 20, the positive electrode 10 and the negative electrode 20 penetrate the thermocouple plates 19, the thermocouple plates 19 are electrically connected to the storage battery 25, and the thermocouple plates 19 are connected to the controller 7 through a bus. The thermocouple plates can measure the temperature in the electrolytic cell, which can ensure that the temperature in the electrolytic cell is kept within the optimal reaction temperature range, thereby improving the electrolysis efficiency and promoting the generation of hydrogen.

[0046] The method of using the portable integrated hydrogen generation and storage device of the present invention is basically the same as that of Example 1, except that:

[0047] During the water electrolysis process, the temperature of the electrolytic cell 18 rises, resulting in a hot end and a cold end of the thermocouple plate 19. When the temperature of the hot end and the cold end of the thermocouple plate 19 are different, an electromotive force will be generated in the circuit, and the electric energy generated by the electromotive force is collected in the storage battery 25. The controller 7 also monitors the temperature in the electrolytic cell 18 through the thermocouple plate 19, controls the current, the speed of the stirring rod and the amount of photocatalyst released to control the temperature generated during the water electrolysis process, and ensures that the temperature in the electrolytic cell 18 is within the preset electrolysis temperature range.

[0048] Example 3

[0049] The method is basically the same as the above-mentioned embodiment 1, except that a plurality of deoxidizer plates 22 are fixedly connected to the inner bottom wall of the purification tank 21 by bolts. The deoxidizer plates react chemically with oxygen through the deoxidizer inside them, absorb oxygen and convert it into harmless substances, thereby significantly improving the purity of hydrogen.

[0050] The method of using the portable integrated hydrogen generation and storage device of the present invention is basically the same as that of Example 1, except that:

[0051] The hydrogen and oxygen entering the purification tank 21 will sink and float upward due to the difference in molecular density, and the oxygen will contact the deoxidizer plate 22 on the bottom wall. In this embodiment, the deoxidizer plate 22 uses glucose oxidase as a deoxidizer. The glucose oxidase in the deoxidizer plate 22 reacts with the oxygen in the hydrogen to catalyze the oxidation of glucose into gluconic acid, while consuming the oxygen mixed in the hydrogen, thereby improving the purity of the hydrogen.

[0052] Example 4

[0053] It is basically the same as the above-mentioned embodiment 1, except that: the gas pipe 15 is L-shaped, and the diameter of the end connected to the collection tank 12 is smaller than the diameter of the end connected to the purification tank 21. The design that the diameter of the end of the gas pipe is smaller than the diameter of the head end can generate a certain pressure difference when the airflow passes through, which helps to better control the flow rate and direction of the airflow. This design makes the gas more stable during the transmission process.

[0054] The method of using the portable integrated hydrogen generation and storage device of the present invention is basically the same as that of Example 1, except that:

[0055] The purified hydrogen is transmitted to the collection tank 12 through the L-shaped gas pipe 15. The L-shaped design helps to reduce the turbulence and loss of hydrogen during the transmission process and improve the transmission efficiency. The diameter of the end of the gas pipe 15 is smaller than the diameter of the head end. This design allows the hydrogen to gradually accelerate during the transmission process and form a more concentrated airflow when entering the collection tank 12. This helps the hydrogen to be more evenly distributed between the guide plate 14 and the solid hydrogen storage plate 11, thereby improving the storage efficiency and the purity of the hydrogen.

[0056] Example 5

[0057] The invention is basically the same as the above-mentioned embodiment 1, except that a handle 4 is welded on one side of the top of the box 1, and a plurality of wheels 6 are rotatably matched at the bottom of the box 1. The design of the handle enables the user to easily push and carry the box without having to find additional grip points or use other auxiliary tools. The addition of the wheels enables the box to be easily moved on different ground surfaces without the user having to carry it laboriously. The design of the wheels improves the mobility and convenience of the device.

[0058] The method of using the portable integrated hydrogen generation and storage device of the present invention is basically the same as that of Example 1, except that:

[0059] When the device needs to be moved, the user can hold the handle 4 on the top of the box 1 and easily push the entire device. If the moving distance is far or frequent movement is required, the wheels 6 installed at the bottom of the box 1 can be used for rolling movement.

[0060] Although the content of the present invention has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the present invention. After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur. Therefore, the protection scope of the present invention should be limited by the appended claims.
