  • Nel Hydrogen S Series Gas Generators

Nel S Series Hydrogen Generators

Nel S10, S20, and S40 hydrogen generators effectively operate by utilizing a Proton Exchange Membrane (PEM) to produce high purity hydrogen gas from water. A PEM hydrogen generator cell consists of two electrodes (an anode and a cathode), which are separated by the ion exchange membrane. To produce the highest purity of hydrogen up to up to 99.9995% purity. Commercial hydrogen generators that are used for on-site hydrogen production provide a safe, convenient, and cost-effective alternative to using high pressure cylinders of H2.
Nel S Series hydrogen generator units are efficiently designed and use load-following technology to sense demand and adjust production accordingly. Nel hydrogen S Series generators can produce the equivalent of three 6-pack cylinders per week of better than UHP-grade hydrogen 99.9995% every day. Since they are pre-built into integrated, automated, and site-ready enclosures, S Series PEM hydrogen generators replace the need for multiple cylinders and save space while providing quiet and steady operation.
