One end of an exhaust channel B24 in the exhaust passage fixing plate 14 is connected with the inner wall of the lower end of the opening, and the other end is connected with an exhaust channel A3 on the wall surface of the liquid storage tank 5. Hydrogen gas is generated in the discharge breakdown region between the high voltage electrode wire 20 and the low voltage electrode metal ring 23, i.e., inside the opening of the low voltage electrode fixing plate 14. During the hydrogen generation, the liquid level inside the liquid storage tank 5 needs to be controlled, and the liquid level needs to submerge the low-voltage electrode metal ring 23 and be lower than the upper surface of the low-voltage electrode fixing plate 14. The high-voltage electrode wire 20 is inserted into the high-voltage electrode insulating sleeve 21, the upper end of the high-voltage electrode wire is connected with a power supply circuit inside the high-voltage electrode fixing plate 11, the downward pointed end is the discharge position of the high-voltage electrode, the high-voltage electrode wire is always immersed in reaction liquid, and gas is generated from the discharge position of the pointed end of the high-voltage electrode wire 20.
The principle of hydrogen generation is that plasma is generated by discharging and breaking down in liquid at high and low voltage electrodes, and the reaction liquid is decomposed into gas by the synergistic catalysis of high energy aggregation in a plasma discharge channel, so that the premise of stable hydrogen generation is to ensure the stable power supply between the high and low voltage electrodes. The high-voltage end of the power supply is connected with the high-voltage electrode power supply channel 9 in a plug-in mode, and the interface is subjected to insulation sealing treatment. The inside of the high-voltage electrode power supply channel 9 is communicated with the sliding groove 16 of the electrode structure shell 2, the high-voltage end of the power supply source is directly inserted into the bottom end of the sliding groove 16 through the high-voltage electrode power supply channel 9, power is supplied to one end of a high-voltage electrode power supply circuit 19 connected with the high-voltage electrode power supply channel through a metal layer on the inner side of the sliding groove 16, and the other end of the high-voltage electrode power supply circuit 19 is connected with a high-voltage electrode metal wire 20 to finish power supply of the high-voltage end. The low-voltage end of the power supply is connected with the low-voltage electrode power supply channel 8 in a plug-in mode, and the interface is subjected to insulation sealing treatment. The low-voltage end of the power supply source is arranged in the low-voltage electrode power supply channel 8 and is connected with one end of a low-voltage electrode power supply line 22, and the other end of the low-voltage electrode power supply line 22 is connected with a low-voltage electrode metal ring 23, so that the low-voltage end power supply is completed.

The exhaust passage functions to discharge the generated gas out of the hydrogen production module. The gas is generated between the high voltage electrode wire 20 and the low voltage electrode metal ring 23, i.e., inside the opening of the low voltage electrode fixing plate 14. The gas is discharged into the lower section opening of the exhaust passage fixing plate 13 from the inside of the opening of the low-voltage electrode fixing plate 14, the gas enters the exhaust channel B24 inside the exhaust passage fixing plate, the outlet end of the exhaust channel B24 is connected with the exhaust channel A3 on the liquid storage tank 5, and the exhaust process is completed. The exhaust channel B24 connects the lower openings of the exhaust passage fixing plate 13 in series according to the array mode of the high voltage electrode 12, and discharges the gas by stages to reduce the pipe diameter and the internal pressure of the exhaust channel B24, thereby preventing the gas leakage caused by damaging the sealing structure. And trace gas leaks at the radial opening of the high-voltage electrode insulating sleeve 21 in the electrolytic structure shell 2 and the connection between the upper section opening of the exhaust passage fixing plate 13 and the high-voltage electrode insulating sleeve 21, and the pressure balance channel 17 can exhaust the gas in the electrode structure shell 2 to keep the internal pressure stable.

The liquid inlet channel 4 is divided into two ends, which are respectively located at the wall surface of the liquid storage tank 5 and the corresponding position of the low-voltage electrode fixing plate 14, as shown in fig. 5 and 12. The liquid enters the low-voltage electrode fixing plate 14 from the liquid inlet channel 4 and then is discharged into the liquid storage tank 5 through the liquid inlet pipe 25 at the lower end. Liquid can be discharged out of the hydrogen production module through the liquid discharge channel 7, when the reaction liquid is alcohol substances, carbon deposition is separated out and deposited at the bottom of the liquid storage tank 5, and the liquid can be cleaned through the cleaning channel 6 positioned at the bottom of the liquid storage tank 5. The liquid inlet and outlet process is controlled by an external system, and the liquid level is always higher than the discharge area. Partial electric energy which can not be converted into chemical energy in the discharge breakdown process can be converted into internal energy to increase the temperature of the solution, and when the temperature is higher than the boiling point of the liquid, a large amount of liquid is vaporized and discharged through an exhaust channel, so that the difficulty in post-treatment of gas is increased. Therefore, the liquid in the liquid storage tank 5 is controlled to be in a proper temperature range through liquid inlet and outlet heat exchange, and meanwhile, the research finds that the discharge parameters at different liquid temperatures have large differences, and the heat exchange process of the liquid inlet and outlet can be reasonably controlled according to the temperature change and the theoretical model of energy efficiency.
