  • Unsupported palladium alloy membranes and methods of making same
    Patent number: 9044715
    Abstract: The invention provides support-free palladium membranes and methods of making these membranes. Single-gas testing of the unsupported foils produced hydrogen permeabilities equivalent to thicker membranes produced by cold-rolling. Defect-free films as thin as 7.2 microns can be fabricated, with ideal H2/N2 selectivities as high as 40,000. Homogeneous membrane compositions may also be produced using these methods.
    Type: Grant
    Filed: August 22, 2008
    Date of Patent: June 2, 2015
    Assignee: Colorado School of Mines
    Inventors: J. Douglas Way, Paul Thoen, Sabina K. Gade
