What is Alkaline Electrolyzer?
An alkaline electrolyzer is a device that splits water into hydrogen and oxygen through electrolysis. It uses an alkaline electrolyte, typically potassium hydroxide, and two electrodes separated by a porous diaphragm. This setup allows for the passage of hydroxyl ions, enabling the electrochemical reactions. At the cathode, water is reduced to hydrogen gas and hydroxyl ions. At the anode, hydroxyl ions are oxidized to oxygen gas and water. Alkaline electrolyzers are robust and can utilize non precious metal catalysts, making them economically attractive for producing high purity hydrogen. Their simplicity and established technology contribute to their significance in industrial hydrogen production and emerging energy applications.
