[0026] In one embodiment of this utility model, a fixing mechanism 4 is provided inside the frame 1. A block 41 is fixedly installed on the surface of the frame 1, a small block 42 is fixedly installed on the surface of the block 41, and a cathode circulation pump 43 is fixedly installed on the surface of the small block 42. A movable groove 44 is opened on one side surface of the frame 1, and a long block 45 is fixedly installed on the surface of the frame 1.

The platform is designed with multiple PP material electrolyte leakage collection tanks 313, which are installed in the form of drawers below the electrolytic cell and the anode and cathode circulation tanks. PP material is resistant to alkali corrosion and hydrogen peroxide oxidation. When electrolyte leakage occurs, the leaked electrolyte will flow into the electrolyte leakage collection tank 313. This leakage collection tank design can greatly reduce the corrosion and oxidation of the frame 1, equipment, and instruments by the electrolyte, prevent electrolyte leakage to other areas of the laboratory, avoid corrosion of other items, and ensure the safety of operators, preventing personnel from being harmed by the electrolyte.

[0027] Working principle: In the cathode circulation, the cathode solution is stored in the cathode circulation tank 37. The cathode circulation pump 43 is fixed by the fixing mechanism 4, such as the square block 41 and small block 42 on the frame 1. Its output end is connected through the connecting pipe 46 to draw the cathode solution from the cathode circulation tank 37 and send it to the cathode of the fuel cell stack 311. At the cathode of the fuel cell stack 311, the cathode solution undergoes an electrochemical reaction with oxygen to generate alkaline hydrogen peroxide. To ensure the continuous and stable reaction, water is continuously added to the cathode circulation tank 37. This maintains a stable balance of hydrogen peroxide concentration and ensures the consistency of reaction conditions. As water is added, the liquid level in the cathode circulation tank 37 rises. At this time, the solution is discharged by the cathode drain pump to control the liquid level stability. The discharged solution is the product alkaline hydrogen peroxide, which can be collected and further processed. The anolyte solution is stored in the anolyte circulation tank 38. The anolyte circulation pump 312 draws the anolyte solution from the anolyte circulation tank 38 and sends it to the anode of the fuel cell stack 311. At the anode, sodium hydroxide undergoes an electrochemical reaction and is oxidized into oxygen and water. The continuous replenishment of liquid alkali into the anolyte tank 38 will cause the anolyte liquid level to rise. At this time, excess sodium hydroxide solution will be discharged. The discharged sodium hydroxide solution can be used in the bleaching process, realizing the effective utilization of resources and avoiding raw material waste. During the electrolysis process, excess oxygen is generated on both the anode and cathode sides. This oxygen eventually enters the low-pressure oxygen tank 31 together. The low-pressure oxygen tank 31 is connected to the oxygen tank 32 via pipe 32. Connected to oxygen compressor 34, which is mounted on protrusion 33 of frame 1, oxygen compressor 34 pressurizes oxygen in low-pressure oxygen tank 31 and sends it to high-pressure oxygen tank 36. The oxygen in high-pressure oxygen tank 36 mixes with fresh oxygen and is then sent to the cathode side to participate in an electrochemical reaction, forming an oxygen recycling system. This improves oxygen utilization efficiency and reduces operating costs. DC power supply 39 provides the necessary DC power for the electrolysis of fuel cell stack 311, ensuring energy supply for the electrolysis reaction. The power distribution cabinet on the right provides an instrumentation control system, controlling and monitoring the electrical equipment and instruments of the entire test platform. Data generated during the test is transmitted to the operating computer for recording, facilitating operator monitoring of the test. The process and results are analyzed and managed. Considering the corrosive and oxidizing properties of the anode and cathode electrolytes, leakage may occur during testing. The platform is designed with multiple PP electrolyte leakage collection tanks 313, which are installed in the form of drawers under the electrolytic cell, anode and cathode circulation pump, and anode and cathode circulation tank. PP material is resistant to alkali corrosion and hydrogen peroxide oxidation. When electrolyte leakage occurs, the leaked electrolyte will flow into the electrolyte leakage collection tank 313. This leakage collection tank design can greatly reduce the corrosion and oxidation of the frame 1, equipment, and instruments by the electrolyte, prevent electrolyte leakage to other areas of the laboratory, avoid corrosion of other items, and ensure the safety of operators, preventing personnel from being injured by the electrolyte.
