Proton PEM electrolyzer

Proton PEM electrolyzer

Proton PEM electrolyzer


The PEM electrolyzer provides a superb platform for numerous applications and its modular design makes it an excellent option for small to large-scale industrial solutions. Containerized for reliable, turn-key outdoor installations with minimal maintenance and including all sub-process equipment including hydrogen purification and a PLC control system.

PEM electrolyzers are an option for traditional industries but can also be applied to renewable energy hydrogen generation, as part of the hydrogen infrastructure system for a hydrogen refuelling station, used in the field of transportation, power storage, intelligent micro-grid and other specialist fields.

The suitability of PEM electrolyzers for use with renewable energy sources for hydrogen production, combined with the use of pure water rather than electrolytic solutions simplifies the process, leads to higher hydrogen purity and offers truly green hydrogen production. Compared with the Alkaline-type H2 generator, it can be operated at high current densities, which can result in reduced operational costs and electrolytic efficiency up to 85% or better.
