Description

Technical Field

[0001] This utility model relates to the field of electrolyte tank technology, and more specifically, to an electrolyte tank. Background Technology

[0002] An electrolytic cell is a device used to produce hydrogen and oxygen through water electrolysis. Its core components include the cell body, anode, and cathode, typically separated by a diaphragm between the anode and cathode chambers. Under direct current, an oxidation reaction occurs in the anode chamber to produce oxygen, while a reduction reaction occurs in the cathode chamber to produce hydrogen. Electrolytic cells are widely used in renewable energy fields such as photovoltaics and wind power, supporting sustainable energy development and clean energy conversion. With advancements in green hydrogen production technology, electrolytic cells occupy an important position in the hydrogen energy industry chain. However, the water entering the cell naturally comes into contact with the electrodes, affecting electrolysis efficiency. Furthermore, existing electrolyte tanks do not filter the incoming water, and impurities in the water affect the quality of electrolysis. Additionally, some impurities easily adhere to the electrodes and pipe walls, making cleaning difficult. Therefore, we propose an electrolyte tank design. Utility Model Content
