Polymer Exchange Membrane (PEM) electrolyzers are advanced electrochemical devices designed for green hydrogen production through the electrolysis of water. They stand out for their high effectiveness, continuity and ease of operation, making them a core technology for the global transition to a low-carbon energy system.
The PEM electrolyzer consists of a polymer exchange membrane (PEM) which enabling proton (H⁺) transfer, two electrodes (anode and cathode). When an electric current is applied, water molecules are split into oxygen gas, protons, and electrons at the anode and protons (H⁺) migrate through the PEM toward the cathode. At the anode, electrons from the external circuit combine with protons to form hydrogen gas (water motes are resolved into hydrogen ions( protons) and oxygen ions. The protons pass through the membrane to the cathode, while the oxygen ions resettle to the anode. At the cathode, the protons combine with electrons to form hydrogen gas (H₂). Then, high-purity hydrogen can be collected from the cathode side.
Technical Advantages
Optimizing Flow Field Structure VS High-Performance Durability Test
Flow field simulation optimization, PEM electrolytic cell to achieve uniform distribution of electrolyte and gas, significantly improve the electrolysis efficiency, reduce energy consumption, effectively reduce the performance deviation of each electrolysis unit, to ensure the stability of equipment operation and hydrogen production consistency.
The PEM electrolyzer builds a solid barrier for the safe and reliable operation of the equipment by virtue of multiple safety protection designs. In the face of 4 MPa extreme working conditions, the double-channel sealing structure plays a central role. Special sealing materials and precision manufacturing processes are used to strictly control the leakage rate below 0.1 %/h, effectively eliminating the risk of hydrogen leakage and avoiding safety hazards caused by gas leakage.
The polarization curve test verifies that the PEM electrolytic cell has efficient electrochemical reaction performance, and there is no obvious performance attenuation with the durability test. The stable and reliable quality is proved by the data, so that customers are confident in the safety and efficiency of the long-term operation of the equipment.
