PEM electrolysis is a method utilized to produce hydrogen gas by electrolyzing water. This methodology involves passing an electric current through a solution of water, which causes the substances in the water to split into hydrogen and oxygen gases. The PEM in PEM electrolysis stands for proton exchange membrane, a targeted material that promotes the movement of protons (H+) across itself.
The process begins with an input of electricity, which powers the chemical reaction within the electrolyzer. As the current flows through the membrane, water molecules are divided into hydrogen ions (H+) and hydroxide ions (OH-). The H+ ions then migrate through the proton exchange membrane to the cathode, where they combine with electrons to form hydrogen gas. Simultaneously, at the anode, the OH- ions react with each other to produce oxygen gas and water.
The resulting hydrogen gas can be collected for various applications, such as fuel cells, industrial processes, or as a potential fuel copyright. PEM electrolysis offers several advantages over traditional methods of hydrogen production, including its high efficiency, low operating temperatures, and ability to produce refined hydrogen gas.
