PEM hydrogen generator
A PEM hydrogen generator is a device that produces hydrogen on demand by electrolysing purified water across a solid proton-exchange membrane.
- Uses a solid polymer membrane instead of a liquid alkaline electrolyte.
- Generates gas while running, so no bulk storage vessel is needed.
- Output rate is set by applied electrical current.
Definition
A PEM hydrogen generator is a device that produces hydrogen on demand by electrolysing purified water across a solid proton-exchange membrane.
Purity
With no dissolved alkali in the cell, the output stream carries moisture rather than caustic aerosol, so conditioning focuses on drying and filtration.
Production
Rated by nominal hydrogen output, electrical input, feed-water quality and service interval for consumables such as deionising resin.
Applications
Industrial units supply combustion equipment; small units serve consumer modality equipment. Neither application is a claim about results.
