Alkaline electrolytic cells usually use potassium hydroxide (KOH) or sodium hydroxide (NaOH) solution as the electrolyte, with a concentration of generally 20% -30%.
Under the action of direct current, water molecules undergo a reduction reaction at the cathode, generating hydrogen gas (H ₂) and hydroxide ions (OH ⁻). Under the action of an electric field, hydroxide ions pass through the membrane and reach the anode, where they lose electrons and generate oxygen (O ₂) and water molecules.
Advantage
1. Mature technology
The alkaline electrolysis cell technology has been industrialized since the mid-20th century. After years of development, the technology has become very mature and widely used in various industries, accumulating a large number of practical cases and experience.
2. Cost effectiveness
Low equipment cost: The alkaline electrolysis cell has a relatively low cost and does not require precious metal catalysts, thereby reducing overall costs.
3. Easy to operate
The structure of the alkaline electrolytic cell is simple, easy to operate, and user-friendly
4. Widely applicable
The alkaline electrolysis cell is widely recognized in the hydro electrolysis hydrogen production industry and has a large number of application examples, which can meet the needs of continuous and stable operation.
