Alkaline Water Electrolysis

Alkaline water electrolysis utilizes two electrodes operating in a liquid alkaline electrolyte solution, usually potassium hydroxide (KOH). Potassium hydroxide is a strong base and is caustic. When water is alkaline,  there are ions in the water to conduct electricity for electrolysis to occur. These electrodes are separated by a diaphragm, separating the product gases and transporting the hydroxide ions from one electrode to the other. Proton exchange technology removes the need for strong and caustic bases that are necessary in order to drive the electrolysis process.
