Proton exchange membrane (PEM) electrolyzers have emerged as a promising technology for the synthesis of hydrogen, driven by the increasing demand for clean and sustainable energy options. These systems utilize a solid polymer electrolyte to partition hydrogen and oxygen ions, facilitating an efficient electrochemical process. This review provides

The PEM electrolyzer stands as a frontrunner in the realm of clean hydrogen production. This innovative technology leverages an electrochemical process to split H2O into its constituent elements: hydrogen and oxygen. The electrochemical reaction is driven by an external electrical current, facilitated by a specialized membrane that selectively allo
