SPE hydrogen generators, fully known as Solid Polymer Electrolyte Membrane water electrolysis hydrogen production, utilize proton exchange membranes (such as perfluorosulfonic acid membranes) to replace the liquid electrolyte in traditional alkaline electrolytic cells. The operational process is as follows: Reaction Process: Anode: Deionized water undergoes oxidation catalyzed by a catalyst (e.g., platinum), producing oxygen, hydrogen ions (H⁺), and electrons. Cathode: Hydrogen ions migrate through the proton exchange membrane to the cathode, where they combine with electrons to form hydrogen gas. Key Components: Membrane Electrode Assembly (MEA): The catalyst is directly embedded on both sides of the proton exchange membrane, forming a “zero-gap” structure that minimizes electrical resist.
