Hydrogen Purifiers

The ACI Proton Purifier produces ultra pure hydrogen by the process of selective diffusion through palladium alloy membranes. Hydrogen molecules are absorbed onto the surface of the palladium alloy membrane where they dissociate into separate hydrogen atoms. Electrons from the atoms are transferred into the electron cloud of the metal alloy releasing protons.

Pressure differential across the membrane forces the protons to pass through the alloy lattice. When they emerge from the other side, they combine with free electrons to reform hydrogen molecules.

The output hydrogen gas typically contains less than 1ppb oxygen and water vapour. Other impurities are below detection level.
