Proton Exchange Membrane (PEM) water electrolysis provides a sustainable solution for the future clean production of high pure hydrogen.

When a water molecule passes through electrochemical process water molecules split into hydrogen and oxygen gases, this process is called water electrolysis. Electricity is used for splitting hydrogen and oxygen into their gaseous phase. The basic equation of water electrolysis is written as Eq.1. This technique produces clean energy without the emission of pollution by utilizing electricity.
