[0002] Hydrogen energy is an ideal clean energy with huge development potential. The use of hydrogen energy needs to start with hydrogen production. The hydrogen production process is divided into gray hydrogen, blue hydrogen and green hydrogen according to the carbon emission intensity. Green hydrogen is produced by electrolyzing water in an electrolyzer and is a renewable energy source. The original intention of the development of the hydrogen energy industry is zero carbon or low carbon emissions. Therefore, green hydrogen produced by electrolyzing water is the development direction of the future energy industry.

[0003] Hydrogen production by water electrolysis is a common method of hydrogen production. However, the traditional process of hydrogen production by water electrolysis has the problem of being unable to accurately detect changes in the electrolyzer voltage, making it difficult to determine the product efficiency of the electrolyzer. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] Furthermore, the slide rail is embedded in the diaphragm and the bottom side of the cylinder frame.

[0012] Furthermore, the sliding block is slidably installed in the sliding groove, and the first screw rod is screwed and sleeved with the screw hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the electrolyzer is conducting water electrolysis to produce hydrogen, the probe rod is used to probe into the inside of the electrolyzer and contact the electrolyte. The probe rod and the limit slider are both made of conductive materials. The limit slider is slidably connected to the conductive slide rail to keep the circuit unobstructed. Then, the voltage monitoring device is connected to the power-on interface. The conductive slide rail is connected to the power-on interface by wires to monitor the voltage state of the electrolysis reaction at all times. This allows the staff to adjust the voltage and the water content in the electrolyte in a timely manner according to the monitored electrolyte voltage to maintain the electrolysis efficiency. The slider can also be controlled to slide in the inspection track to change the voltage monitoring position and improve the monitoring effect.

[0015] 2.

The two probe rods are used as the positive and negative poles of the voltage detection circuit to perform voltage detection. When the probe rod is raised, it is inserted from the insertion slot and pushes open the one-way valve port to enter the anode chamber or cathode chamber. The one-way valve port keeps the insertion slot sealed.

[0016] 3. Use motor No. 1 to rotate screw No. 1 and rub the screw hole, thereby controlling the slider to slide in the slide slot to change the position of the slider below the anode chamber and cathode chamber in the electrolytic cell, so as to achieve the effect of changing the monitoring location.
