PEM electrolysis is a process utilized to produce hydrogen gas by electrolyzing water. This system involves passing an electric PEM electrolyzer 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 enables the movement of protons (H+) across itself.
The process begins with an input of electricity, which propels the chemical reaction within the electrolyzer. As the current flows through the membrane, water molecules are separated into hydrogen ions (H+) and hydroxide ions (OH-). The H+ ions then travel 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 harvested for various applications, such as fuel cells, industrial processes, or as a potential energy copyright. PEM electrolysis offers several advantages over conventional methods of hydrogen production, including its high efficiency, low operating temperatures, and ability to produce pure hydrogen gas.
