The core principle of the PEMHPS System is centered on advanced Proton Exchange Membrane (PEM) water electrolysis. Under the influence of direct current, the system utilizes high-activity catalysts to split pure water into hydrogen and oxygen. The proton exchange membrane acts as the critical separator, allowing only protons to pass through and combine into hydrogen gas. This physical isolation inherently ensures an output purity of 99.999%, meeting the stringent requirements of precision industrial and scientific research without extensive post-processing.

Operationally, the system emphasizes pressure controllability and rapid response. With a production range of 5–50 Nm³/h and an adjustable outlet pressure of 0–3 bar, it can dynamically tune hydrogen flow based on downstream demand. The architecture incorporates a modular, explosion-proof design to guarantee structural stability and operational safety under all conditions. By seamlessly coupling with fuel cell generators, PEMHPS establishes a sustainable "Power-to-Gas-to-Power" loop, transforming intermittent renewable energy into a stable hydrogen reserve and serving as a pivotal tool for green hydrogen supply.
