Understanding the Fundamentals of PEM Electrolysis Technology
PEM electrolysis is a technology for producing hydrogen gas by splitting water molecules into their constituent elements. This electrolytic reaction is driven by an electric current passed through a specialized membrane, known as a proton exchange membrane (PEM). The PEM acts as a selective barrier, allowing only protons to pass through while blocking the flow of electrons and hydroxide ions. As a result, hydrogen gas is created at one electrode, and oxygen gas at the other.
This core process offers several advantages over traditional electrolysis methods, including higher efficiency, faster reaction rates, and the ability to operate at minimal temperatures. PEM electrolysis is becoming increasingly attractive as a clean and sustainable source for hydrogen production, particularly in applications such as fuel cells, industrial processes, and grid-scale energy storage.
