How does a Proton Exchange Membrane (PEM) Electrolyzer work?
Using an electrochemical process, the Proton Exchange Membrane Electrolyzer (PEM) splits water molecules into hydrogen and oxygen through a proton exchange membrane. Electrolysis occurs within the PEM electrolyzer's cell stack, which is composed of multiple layers of specialized materials.
An electrolyzer's proton exchange membrane is made of polymer material, which acts as a selective barrier that allows only protons (positively charged ions) to pass through while blocking other particles. By applying an electric current and feeding water into the electrolyzer, a series of chemical reactions occurs.
By traveling through the membrane towards the cathode side, positively charged protons create electrical energy while negatively charged electrons travel through an external circuit. In order to produce pure hydrogen gas, these protons combine with electrons on the cathode side and reduce hydrogen ions from water molecules.
On the anode side, oxygen gas is generated by oxidizing the hydroxyl ions produced during water splitting. These distinct processes occur simultaneously, but are physically separated by the proton exchange membrane.
In comparison to other technologies like alkaline electrolyzers, PEM electrolyzers can operate at lower temperatures and pressures, making them more efficient and versatile.
We will explore how this remarkable technology revolutionizes sectors such as energy production, industrial processes, and even transportation!
What is the working principle of a PEM electrolyzer?
Proton Exchange Membrane Electrolyzers, or PEMs, are electrochemical devices that use an innovative technology to split water molecules into hydrogen and oxygen.
In a PEM electrolyzer, the proton exchange membrane acts as a solid polymer electrolyte. It allows protons (H+) to pass through while blocking electrons and other ions.
As water is fed into the electrolyzer's cathode compartment, it is split into protons (H+) and hydroxide ions (OH-) via an electric current applied across electrodes coated with catalysts like platinum or iridium oxide.
Through specialized channels called flow fields, hydroxide ions migrate towards the anode compartment, while protons move through the proton exchange membrane.
More catalyst-coated electrodes in the anode compartment facilitate another reaction where these migrating protons combine to form hydrogen gas (H2). The oxygen produced from hydroxide ions escapes.
Electrical energy is converted into chemical potential energy by PEM electrolyzers by separating water with electricity. In addition to fuel cells for transportation, hydrogen can also be used in industrial processes that require clean energy.
PEM electrolyzers have a unique design that delivers high purity hydrogen gas on-demand without producing greenhouse gases during operation, making them a promising solution for sustainable energy production.
