  • Device and method for the measurement of gas permeability through membranes
    Patent number: 7088106
    Abstract: A device for the measuring membrane permeability in electrical/electrochemical/photo-electrochemical fields is provided. The device is a permeation cell and a tube mounted within the cell. An electrode is mounted at one end of the tube. A membrane is mounted within the cell wherein a corona is discharged from the electrode in a general direction toward the membrane thereby generating heated hydrogen atoms adjacent the membrane. A method for measuring the effects of temperature and pressure on membrane permeability and selectivity is also provided.
    Type: Grant
    Filed: December 23, 2004
    Date of Patent: August 8, 2006
    Assignee: University of Wyoming
