It is a type of electrolyzer that is characterized by having two electrodes operating in a liquid alkaline electrolyte solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) Alkaline water electrolysis is one of the easiest methods for hydrogen production although it is relatively expensive technology. If relatively small quantities of hydrogen are required, on-site electrolysis of water may result more economical than other methods. This technique is very clean and produces more than 99.989% purity of hydrogen gas Alkaline Electrolysis Alkaline electrolysis makes use of a diaphragm between the catholyte and the anolyte in order to avoid contact between the two gases produced, that is, the hydrogen and oxygen, respectively, and to allow transfer of the other liquid mixture components, particularly H2O and OH−
