PEM technology

PEM technology uses direct current to split pure water into hydrogen and oxygen.

The water molecules react to form oxygen and protons; the electrons are freed. The protons move across a very thin conducting membrane and combine with electrons from the external circuit to form hydrogen gas.

PEM electrolysis is the most effective technology for producing hydrogen from renewable energies.
