Proton laboratory hydrogen generator, when connected to a suitable AC power source and fed with a suitable quality of DI (de-ionized/demineralized) water, produces a continuous stream of pressurized ultra high-purity (UHP) hydrogen gas and automatically maintains a user selected, downstream pressure.
Proton OnSite’s hydrogen generators provide high purity-grade hydrogen on demand. Guaranteed purity of hydrogen is achieved by using a platinum catalyst and Proton Exchange Membrane (PEM) technology to split deionized water into its constituent parts.
When a DC voltage is applied to the electrolyzer, water molecules at the anode are oxidized to oxygen and protons, while electrons are released. The protons (H+ ions) pass through the membrane to the cathode where they meet electrons from the other side of the circuit, reducing to hydrogen gas.
