PEM Hydrogen Production Electrolyzers

PEM hydrogen production electrolyzers (Proton Exchange Membrane Electrolyzers) use proton exchange membranes as solid electrolytes and pure water as raw materials to produce high-purity hydrogen and oxygen through electrolysis. With titanium-based coated electrodes as core anode/cathode components, they feature high energy efficiency, high hydrogen purity, safety and environmental friendliness, widely used in energy, chemical, transportation and energy storage fields, and are one of the important technical paths to realize the hydrogen economy. The manufacturing process includes: anodes (Gr1/Gr2 titanium coated with Pt, IrO₂, RuO₂ for excellent oxygen evolution), cathodes (titanium/stainless steel with Pt-group metals for efficient hydrogen evolution), MEA (high-performance Nafion membrane hot-pressed with catalyst/diffusion layers), and bipolar plates (titanium flow plates with anti-corrosion coatings). These electrolyzers have ≥99.999% hydrogen purity, second-level start-stop respons…
