  • Hydrogen purifier
    Patent number: 3972695
    Abstract: Pressurized impure hydrogen gas from a hydrogen generator, bottled hydrogen, or other source is fed to a separate palladium purifier unit having an ultrapure hydrogen output for analytical use, and the like. A palladium-silver tube is inserted into a jacket tube to form a tube assembly which is coiled around a heated block. The jacket tube receives the impure hydrogen and the palladium-silver tube passes pure hydrogen which is transferred to an outlet for use with the gas impurities being discharged at a vent end of the jacket tube.
