Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydrogen production by hydrolysis, and in particular relates to an electrolytic cell. Background Art
[0002] An alkaline electrolyzer, a device that uses direct current to decompose water into hydrogen and oxygen, is one of the core components of hydrogen production technology. An electrolyzer is typically assembled from components such as terminal blocks, gaskets, plates, electrodes, and a diaphragm. During the electrolysis process, water molecules gain electrons at the cathode, forming hydrogen and hydroxide ions. The hydroxide ions then pass through the diaphragm to the anode, where they are reacted with voltage to produce oxygen and water.
[0003] Traditional electrolyzers mostly use a timed fixed structure, which cannot adjust the position of the electrolytic components, limiting the adaptability of the equipment. In specific application scenarios, the fixed support and adjustment mechanism cannot meet the needs of different heights and support positions, resulting in inconvenient operation. In addition, traditional equipment lacks multi-position adjustment functions, which affects the precise control of the electrolysis process and is difficult to adapt to complex process requirements, resulting in low production efficiency. The flexibility and applicability of the equipment are greatly limited and need to be improved. At the same time, in the process of electrolytic hydrogen production, electrical energy is converted into chemical energy, and part of the energy is released in the form of heat energy, which not only causes energy waste, but also poses a safety hazard.

[0018] like Figures 1 to 3 As shown, the present application provides an electrolytic cell, comprising two end plates 1 arranged relative to each other, the inner surfaces of the two end plates 1 are respectively provided with an anode plate and a cathode plate, the anode plate is connected to the positive pole of a DC power supply, and the cathode plate is connected to the bipolar pole of a DC power supply, and a number of electrolysis chambers are provided between the two end plates 1, the end plates 1 and the electrolysis chambers are pressed together by screws to form a columnar structure, and electrolyte channels, hydrogen channels and oxygen channels are provided in communication between the end plates 1 and each electrolysis chamber. Each electrolysis chamber is divided by two adjacent plates and includes positive and negative bipolar plates, an anode electrode, a diaphragm, a sealing gasket, and a cathode electrode. During electrolysis, an oxidation reaction occurs at the anode electrode interface, and a reduction reaction occurs at the cathode electrode interface. The diaphragm separates the water electrolysis chambers of the water electrolyzer into a cathode region and an anode region, and separates the generated hydrogen and oxygen to prevent hydrogen and oxygen from penetrating each other, but ions can migrate. In a water electrolysis cell, two isolated volumetric units are called cathode chambers: one is the cathode chamber, also known as the hydrogen chamber; the other is the anode chamber, also known as the oxygen chamber. The channels connecting each of the cathode chambers and transporting alkaline solution into them are called liquid channels. Channels located inside the water electrolyzer are called internal liquid channels; those located outside are called external liquid channels. Gas channels connect to each hydrogen or oxygen chamber and discharge hydrogen or oxygen gas. The channels that discharge hydrogen are called hydrogen channels, and those that discharge oxygen are called oxygen channels. Channels located inside the water electrolyzer are called internal gas channels, while those located outside are called external gas channels.
[0019] A support assembly is provided at the lower end of each end plate 1. The support assembly includes a base 2, an outer shell 3, and a support body 4. The outer shell 3 is provided on the upper end surface of the base 2. The support body 4 is provided within the outer shell 3 and can reciprocate in the vertical direction. The lower end of the end plate 1 is fixedly provided on the upper end surface of the support body 4. Specifically, a lifting motor 5 is provided on the base 2. A ball screw pair 6 is connected to the output shaft of the lifting motor 5. A lifting frame 7 is provided on the nut of the ball screw pair 6. The lifting frame 7 is connected to the support body 4, so that the support body 4 is provided within the outer shell 3 and can reciprocate in the vertical direction. This ensures the precise vertical movement of the lifting frame 7 and the support body 4, and the structure is stable and the operation is reliable, and stable lifting performance can be maintained even after long-term operation. Furthermore, a buffer groove is provided on the lower end surface of the base 2.
[0020] The electrolytic cell also includes a heat pipe 10, which is coiled around the periphery of the electrolytic chamber along the length of the electrolytic cell.

Both ends of the heat exchange copper pipe 15 are connected to the connecting pipes 11 on both sides of the water tank 12, forming a closed heat exchange circuit with the heat exchange copper pipe 15 and the heat pipe 10.
[0021] Furthermore, a scale groove 9 is provided on the outer shell 3 away from the installation side of the lifting motor 5, and a pointer 8 is provided on the lifting frame 7 facing the scale groove 9. The scale groove 9 provides a clear and intuitive height indication, which facilitates the operator to accurately locate the position of the support body 4, thereby enhancing the accuracy and convenience of equipment operation.
[0022] Working Principle: The lifting motor 5 drives the ball screw 6, which in turn controls the lifting frame 7 to drive the support body 4 in vertical reciprocating motion within the outer shell 3, adjusting the height of the electrolytic cell to suit different process requirements. A pointer 8 is fixed to the lifting frame 7 and slides within the graduated groove 9, accurately indicating the current height position. The heat pipe 10 is connected to the connecting pipe 11, with both ends connected to the water tank 12. A water pump 13 operates on the side of the water tank 12, pushing water through the heat pipe 10 and the heat exchange copper tube 15, achieving efficient heat conduction and enabling heat recovery.
[0023] The advantages and technical effects of the present invention are as follows: Due to the adoption of the above-mentioned technical solution, the electrolytic cell can be adjusted and fixed at different positions, which not only meets the diverse requirements of the electrolytic cell in terms of height and support position, but also improves the adaptability of the equipment under different working conditions. At the same time, it can collect heat from the electrolytic cell during use, which is beneficial for improving electrolysis efficiency, reducing energy consumption, allowing energy recycling, and reducing safety hazards. The adjustable support body 4 ensures stability, facilitates precise positioning, and adapts to different reaction conditions, thereby improving electrolysis efficiency and convenient operation.
