  • Electrochemical compression system
    Patent number: 9005411
    Abstract: An electrochemical compressor includes one or more electrochemical cells through which a working fluid flows, and an external electrical energy source electrically connected to the electrochemical cell. Each electrochemical cell includes an anode connected to the electrical energy source; a cathode connected to the electrical energy source; an ion exchange membrane disposed between and in electrical contact with the cathode and the anode to pass an electrochemically motive material of the working fluid from the anode to the cathode, the ion exchange membrane comprising polar ionic groups attached to nonpolar chains; and a non-aqueous solvent comprising polar molecules, the polar molecules of the non-aqueous solvent being associated with and electrostatically attracted to the polar ionic groups of the ion exchange membrane.
    Type: Grant
    Filed: January 11, 2013
    Date of Patent: April 14, 2015
    Assignee: Xergy Inc
