Hydrogen Generator Using Proton Exchange Membrane (PEM)

Nel Hydrogen offers the Hydrogen H-Series generators that use Proton Exchange Membrane (PEM) cell stack and PSA technology to generate ultra-high purity hydrogen for a wide range of applications, such as semiconductor fabrication, generator cooling, materials processing, etc.

The generators are field-upgradeable, modular and designed to contend with delivered hydrogen anywhere across the world. A single H6 unit offers the equivalent of one and one-half jumbo tube trailers every month. In addition multiple systems can be integrated for additional capacity at no extra cost.

The Hydrogen H-Series generators benefit users by enhancing site safety and supply reliability, while reducing hydrogen storage space.
