What is Alkaline hydrogen electrolyzer？

Alkaline hydrogen electrolyzer is a chemical process that splits water molecules into hydrogen and oxygen gases using an alkaline electrolyte solution, typically potassium hydroxide (KOH). It involves using an electrolyzer, consisting of an anode and a cathode immersed in the electrolyte solution.

When an electric current is passed through the electrolyzer, water molecules are ionized, and hydrogen ions (H+) migrate toward the cathode while hydroxide ions (OH-) move toward the anode. At the cathode, hydrogen ions are reduced to form hydrogen gas (H2), while oxygen gas (O2) is evolved at the anode through the oxidation of water molecules. The overall process can be represented as:

2H2O(l) → 2H2(g) + O2(g)
