[0015] The present invention also provides a production method for a novel hydrogen production device, comprising the following steps:

[0016] S1. Composite electrode fabrication: Take multiple positive electrodes, negative electrodes, and a porous insulating layer.

[0039] To facilitate the stratification of the mixed hydrogen and oxygen, a first temperature sensor 16 and a second pressure sensor 17 are respectively installed at the bottom of the inner wall of the gas collecting chamber 14. A first pressure relief valve 15 is installed at the top of the gas collecting chamber 14. The gas outlet of the gas collecting chamber 14 is connected to a first density stratification tower 24 and a second density stratification tower 33 through pipes. A second electric ball valve 18 is installed at the inlet of the first density stratification tower 24. The two gas outlets of the gas collecting chamber 14 respectively transport hydrogen and oxygen to the inside of the first density stratification tower 24 and the second density stratification tower 33 through pipes. The hydrogen and oxygen have different densities inside the first density stratification tower 24 and the second density stratification tower 33. The hydrogen and oxygen will complete the stratification process in the first density stratification tower 24 and the second density stratification tower 33, with hydrogen on top and oxygen on the bottom. A second pressure sensor 17 is installed on the inner wall of the first density stratification tower 24. Temperature sensor 21 and third pressure sensor 22 are installed. A third electric ball valve 23 is installed at the oxygen outlet of the first density stratification tower 24. A fourth electric ball valve 25 is installed at the hydrogen outlet of the first density stratification tower 24. A second pressure relief valve 26 is installed on one side of the top of the first density stratification tower 24.

[0040] The first temperature sensor 16, the second temperature sensor 21, and the third temperature sensor 30 are all model: temperature and humidity sensor RS485 acquisition module;

[0041] The first pressure sensor 13, the second pressure sensor 17, the third pressure sensor 22, and the fourth pressure sensor 32 are all of the following model: pressure sensor RS485 acquisition module;

[0042] The model of controller 28 is: PLC200smart;

[0043] The first electric ball valve 12, the second electric ball valve 18, the third electric ball valve 23, the fourth electric ball valve 25, the fifth electric ball valve 27, the sixth electric ball valve 31, and the seventh electric ball valve 34 are all of the following model: DN40.

[0044] Working principle: First, prepare the composite electrode 8. Take multiple positive electrodes 19, negative electrodes 20, and a porous insulating layer 4. Place the porous insulating layer 4 between the positive electrodes 19 and negative electrodes 20. Encapsulate the multiple positive electrodes 19, porous insulating layer 4, and negative electrodes 20 together to obtain the composite electrode 8. Connect the multiple positive electrodes 19 to the positive relay 6 and positive terminal 3, and connect the multiple negative electrodes 20 to the negative terminal 5 and negative relay 7. Add 500ml of sodium hydroxide aqueous solution and distilled water to the mixing chamber 11 inside the reaction chamber 9 through the feeding pipe 10. Control the positive relay 6 and negative relay 7 to energize the positive electrodes 19 and negative electrodes 20 through the controller 28. After electrode 20 is connected to the electrolyte in the water, an oxidation reaction occurs at the positive electrode, where water molecules lose electrons and produce oxygen. A reduction reaction occurs at the negative electrode, where water molecules gain electrons and produce hydrogen. Through this reaction, water electrolysis produces oxygen and hydrogen. The resulting mixture of hydrogen and oxygen is transported to the inside of the gas collecting chamber 14 through a pipe. Because the porous insulating layer 4 between the positive electrode 19 and the negative electrode 20 is very thin, only a very low DC voltage is needed to successfully electrolyze the electrolyte between the positive electrode 19 and the negative electrode 20, decomposing water molecules (H2O) into oxygen (O2) and hydrogen (H2) through electrolysis. An electrolyte, sodium hydroxide aqueous solution, is added to the water to enhance the conductivity of the electrolyte.

[0045] The two outlets of the gas collecting chamber 14 respectively transport hydrogen and oxygen to the inside of the first density stratification tower 24 and the second density stratification tower 33 through pipelines. Since the hydrogen and oxygen have different densities inside the first density stratification tower 24 and the second density stratification tower 33, they undergo a stratification process, with hydrogen on top and oxygen at the bottom. At this time, the outlets of the third electric ball valve 23 and the sixth electric ball valve 31 supply oxygen to the outside, while the outlets of the fourth electric ball valve 25 and the seventh electric ball valve 34 supply hydrogen to the outside. When the hydrogen production device is working, the first temperature sensor 16, the second temperature sensor 21, the third temperature sensor 30, and the first pressure sensor... Sensors 13, 17, 22, and 32 transmit information to controller 28 in real time. Controller 28 controls the opening and closing of each of the following electric ball valves: 12, 18, 23, 25, 27, 31, 34, 6, 7, 8, 8, 9, 10, 11, 12, 13, 25, 27, 31, 34, 6, and 7. When a malfunction occurs in the hydrogen production unit, the first pressure relief valve 15, 26, and 35 can release pressure in a timely manner. At the same time, alarm 36 generates sound and light prompts to actively inform the staff that a malfunction has occurred in the hydrogen production unit.

[0046] In summary, the composite electrode 8 employs a special design with positive and negative electrodes and a porous insulating layer 4, enabling the hydrogen production device to perform water electrolysis at low voltage to produce hydrogen and oxygen. This design improves electrolysis efficiency, reduces energy consumption, and significantly lowers the cost of hydrogen development and utilization, paving the way for large-scale hydrogen development and utilization in the future. Simultaneously, through the first density stratification tower 24 and the second density stratification tower 33, hydrogen and oxygen can undergo a stratification process internally, with hydrogen on top and oxygen at the bottom, facilitating subsequent transportation and use and improving gas separation efficiency. Multiple temperature and pressure sensors are also installed to monitor the equipment's operating status in real time and transmit the information to the controller 28. The controller 28 controls the opening and closing of each electric ball valve based on the information, ensuring stable operation of the equipment. When a malfunction occurs in the hydrogen production device, the first pressure relief valve 15, the second pressure relief valve, and the third pressure relief valve 35 can promptly release pressure, improving equipment safety.

[0047] The present invention also provides a production method for a novel hydrogen production device, comprising the following steps:

[0048] S1. Fabrication of composite electrode 8: Take multiple positive electrodes 19, negative electrodes 20 and porous insulating layer 4, place the porous insulating layer 4 between the positive electrodes 19 and negative electrodes 20, and encapsulate the multiple positive electrodes 19, porous insulating layer 4 and negative electrodes 20 together to obtain composite electrode 8. Connect the multiple positive electrodes 19 to positive relay 6 and positive terminal 3, and connect the multiple negative electrodes 20 to negative terminal 5 and negative relay 7.

[0049] S2. Feeding and energizing: Sodium hydroxide aqueous solution and distilled water are added to the mixing chamber 11 inside the reaction chamber 9 through the feeding pipe 10. The mixing concentration ratio of sodium hydroxide aqueous solution and distilled water is 1:200. The positive relay 6 and negative relay 7 are controlled by the controller 28 to energize the positive electrode 19 and negative electrode 20, with a voltage of about 1.2 volts.

[0050] S3. After the positive electrode 19 and negative electrode 20 are connected to the electrolyte in the water, a direct current is applied. An oxidation reaction occurs at the positive electrode, where water molecules lose electrons to produce oxygen. A reduction reaction occurs at the negative electrode, where water molecules gain electrons to produce hydrogen. Through this reaction, water electrolysis produces oxygen and hydrogen. The resulting hydrogen and oxygen mixture is transported through a pipeline to the inside of the gas collecting chamber 14. The two outlets of the gas collecting chamber 14 respectively transport hydrogen and oxygen to the inside of the first density stratification tower 24 and the second density stratification tower 33 through pipelines. The hydrogen and oxygen have different densities inside the first density stratification tower 24 and the second density stratification tower 33. Hydrogen and oxygen will complete the stratification process in the first density stratification tower 24 and the second density stratification tower 33, with hydrogen on top and oxygen at the bottom. At this time, the outlets of the third electric ball valve 23 and the sixth electric ball valve 31 supply oxygen to the outside, and the outlets of the fourth electric ball valve 25 and the seventh electric ball valve 34 supply hydrogen to the outside.

200. Control the positive relay (6) and negative relay (7) through the controller (28) to supply DC current to the positive electrode (19) and negative electrode (20). The voltage is 1.15-1.25 volts. S3. Hydrogen production: After the positive electrode (19) and negative electrode (20) are connected to the electrolyte in the water, direct current is applied. An oxidation reaction occurs at the positive electrode, where water molecules lose electrons and produce oxygen. A reduction reaction occurs at the negative electrode, where water molecules gain electrons and produce hydrogen. Through this reaction, water electrolysis produces oxygen and hydrogen. The resulting hydrogen and oxygen mixture is transported through a pipe to the inside of the gas collecting chamber (14). The two outlets of the gas collecting chamber (14) respectively transport hydrogen and oxygen to the first density stratification zone through pipes. Inside the first density stratification tower (24) and the second density stratification tower (33), the hydrogen and oxygen have different densities. The hydrogen and oxygen will complete the stratification process in the first density stratification tower (24) and the second density stratification tower (33), with hydrogen on top and oxygen on the bottom. At this time, the outlet of the third electric ball valve (23) and the sixth electric ball valve (31) supplies oxygen to the outside, and the outlet of the fourth electric ball valve (25) and the seventh electric ball valve (34) supplies hydrogen to the outside.
