[0002] AEM water electrolysis is a method of producing hydrogen and oxygen by electrolyzing water, using an anion exchange membrane to separate the anode and cathode regions. This method has the potential to be more efficient and less costly than traditional alkaline electrolysis or proton exchange membrane electrolysis.
[0003] Existing AEM water electrolysis experiments usually involve pouring water into a test tube and applying electricity through different electrodes to decompose the water. However, since the amount of water gradually decreases during the experiment, water needs to be added manually repeatedly. Moreover, during the experiment, if the pressure inside the test tube exceeds the safety threshold, accidents may easily occur, which is quite inconvenient.
[0004] Therefore, it is necessary to design an AEM water electrolysis experimental device that can automatically replenish water when the water source in the experimental cylinder is insufficient to improve the experimental efficiency, and can cut off the power and sound an alarm when the pressure inside the experimental cylinder is too high to prevent accidents.

DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0020] An AEM water electrolysis experimental device, such as Figure 1 and Figure 2 As shown, it includes an experimental tube 1, a power supply 2, an electrode 3, a wiring block 4, a wire 5, a connector 6, a fixing plate 7, an experimental tube 8, a protection component, a collection component and an automatic water replenishment component. The experimental tube 1 is made of polytetrafluoroethylene and has excellent chemical corrosion resistance. A water injection hole is opened in the front middle of the experimental tube 1 to facilitate water injection. The power supply 2 is placed on the left side of the experimental tube 1. The upper sides of the left and right parts of the power supply 2 are connected to the electrodes 3. The left and right wiring blocks 4 are connected behind the power supply 2. The upper side of the experimental tube 1 is connected to a fixing plate 7. The upper sides of the left and right parts of the fixing plate 7 are connected to connectors 6. The left connector 6 is connected to the left wiring block 4 through a wire 5, and the right connector 6 is also connected to the right wiring block 4 through a wire 5. The middle of the fixing plate 7 is connected to the left and right experimental tubes 8. A protection component is provided between the power supply 2 and the fixing plate 7, a collection component is provided between the rear of the experimental tube 1 and the fixing plate 7, and a collection component is provided at the front of the experimental tube 1.
[0021] like Figure 3 As shown, the protection component includes a current protector 9, a pressure gauge 10 and an alarm 11. The current protector 9 is connected to the front side of the power supply 2, the pressure gauge 10 is connected to the upper front side of the fixing plate 7, and the alarm 11 is connected to the right side of the power supply 2. The alarm 11 is electrically connected to the pressure gauge 10.
[0022] like Figure 4 As shown, the collecting assembly includes a base 12, a connecting frame 121, a collecting bottle 122, a connecting tube 123, an air pump 124 and a support frame 125. The base 12 is placed on the rear side of the experimental tube 1, the connecting frame 121 is connected to the upper side of the base 12, the support frame 125 is connected to the inner side of the upper part of the connecting frame 121, the collecting bottle 122 is connected to the support frame 125, a connecting tube 123 is connected between the collecting bottle 122 and the fixing plate 7, the air pump 124 is connected to the upper side of the collecting bottle 122, and the air pump 124 is connected to the base 12.
[0023] like Figure 5 As shown, the automatic water replenishment component includes a track 13, a buoyancy ball 131 and a slide 132. The track 13 is connected to the inner side of the front of the experimental tube 1. The slide 132 is slidably connected to the track 13. The buoyancy ball 131 is connected to the inner side of the slide 132.
[0024] When using the device, first place the experimental tube 1 in the AEM water electrolysis experimental area, then connect the junction block 4 and the connector 6 through the wire 5, and then connect the water pipe through the water injection hole to allow water to enter the experimental tube 1. The rising water level drives the buoyancy ball 131 to move upward, so that the slide 132 moves on the track 13. After moving to a certain position, the water injection hole is blocked by the slide 132 and no water is injected. Then, power is supplied by the power supply 2. The AEM water electrolysis experiment is carried out through the contact between the experimental tube 8 and the water and the power supply 2. The fixed plate 7 is used for sealing, so that hydrogen and oxygen are generated inside. Then, the air pump 124 is started so that the gas is sucked in through the connecting pipe 123. The hydrogen and oxygen are collected into the collection bottle 122, so that the hydrogen and oxygen can be collected quickly, which is convenient for subsequent separation processing and improves the collection efficiency of hydrogen and oxygen. When the pressure gauge 10 detects that the internal pressure of the experimental cylinder 1 is too high, the current protector 9 is activated to cut off the power, and an alarm is sounded through the alarm 11. When the water source component inside the experimental cylinder 1 is reduced, the buoyancy ball 131 is driven to move downward, so that the slide 132 moves downward, and then the water automatically enters the experimental cylinder 1 through the external water pipe, so that when the water source in the experimental cylinder 1 is insufficient, water can be automatically replenished, thereby improving the experimental efficiency, and when the internal pressure of the experimental cylinder 1 is too high, the power can be cut off and an alarm can be sounded to prevent accidents.
