PEM Water Electrolysis – Compact Ultra-High Purity Solution

We are a specialist manufacturer of small-scale PEM electrolysis hydrogen gas generator for global laboratory, semiconductor and light industrial clients, with a growing installed reference base across Asia, Europe and North America. Our systems adopt integrated Proton Exchange Membrane electrolysis paired with metal membrane secondary purification, delivering certified 9N ultra-pure hydrogen directly to user process lines.

This is the most compact, responsive and clean hydrogen generation technology for low-to-medium flow requirements, requiring only electrical power and deionised water as feed inputs, with zero alkaline electrolyte handling, different from Alkaline Electrolyzer large-scale hydrogen production devices.

PEM Water Electrolysis – PPH Series Solid Membrane Technology

The PPH series PEM electrolysis platform delivers instant, dry ultra-pure hydrogen output, with modular production capacities ranging from 0.1 Nm³/hr up to 0.6 Nm³/hr per standalone unit. For higher aggregate hydrogen demand, multiple PPH modules can be paralleled with shared utility and control subsystems for scalable on-site supply, applicable to small-sized renewable hydrogen plant.

HOW IT WORKS

Proton Exchange Membrane (PEM) Electrolysis Principle

Our PPH electrolyser utilises solid polymer proton exchange membrane core technology. Purified deionised water is split into hydrogen and oxygen via DC electrical power supplied to the membrane stack. High-purity hydrogen evolves at the cathode side of each cell assembly, while oxygen is released at the anode at near-atmospheric pressure and vented safely.

The membrane’s ultra-low gas crossover characteristic completely prevents oxygen contamination of the hydrogen product stream, eliminating secondary purification losses for critical high-purity applications. Differential pressure stack architecture ensures inherently safe, low-complexity continuous operation, a core device for producing Renewable Hydrogen.

What noise levels does the PPH hydrogen generator produce during operation?

The equipment features optimised silent blower and pump assemblies, with sound pressure levels below 70 dB(A) at a 1-metre distance, making it suitable for quiet laboratory, medical and office-adjacent production spaces.

What is the standard preventive maintenance schedule?

Full detailed maintenance timelines and component replacement cycles are documented within the official equipment Operation & Maintenance Manual. Routine minor inspections are scheduled monthly, with major stack and purification module service intervals spanning multiple years of continuous operation.
