Proton Exchange Membrane (PEM) Technology
Proton Exchange Membrane (PEM) electrolyzers are cutting-edge devices that utilize an electrolytic process to split water into hydrogen and oxygen gases. Using a proton exchange membrane as an electrolyte, these systems efficiently transform water into clean, high-purity hydrogen fuel, making them a cornerstone technology for a sustainable energy future.
PEM electrolyzers are known for their high energy efficiency, fast response times, ability to operate at low temperatures, and versatile deployment across applications. With their smaller footprints and modular designs, PEM electrolyzers are ideal for hydrogen production and energy storage in both industrial and renewable energy sectors.

Key Features of PEM Electrolyzers
- High energy efficiency and fast dynamic response.
- Self-pressurized hydrogen gas up to 30 bar (without compression).
- Scalable production from 250 Nm³/h to 1000 Nm³/h with modular designs.
- High hydrogen purity, meeting industrial and renewable energy needs.
- Smaller footprints for easy installation and deployment.
- Standardized systems simplify authority approvals.
