PEM electrolyzers have emerged as a leading technology for the environmentally friendly production here of hydrogen. These devices utilize a proton exchange membrane (PEM) to separate water into its constituent molecules: oxygen and hydrogen. The PEM acts as a selective barrier, allowing protons to travel between while blocking the passage of ions.

PEM electrolyzer technology has undergone significant progresses in recent years, driven by the growing demand for clean and sustainable energy solutions. These advancements encompass improvements in catalyst materials, membrane efficiency, and system design. As a result, PEM electrolyzers are becoming increasingly competitive for various applicati
