  • Fuel cell with proton conducting membrane and with improved water and fuel management
    Patent number: 7951511
    Abstract: The present invention provides a cathode and a fuel cell, which are built to prevent escape of liquids, e.g. water and fuel solution, from the cell. Thus, according to a first aspect thereof, the present invention provides a cathode suitable for use in a fuel cell having a proton conducting membrane, the cathode comprising a plurality of layers including a catalyst layer and a hydrophobic porous support layer, wherein at least one of said plurality of layers is a liquid water leak-proof layer, which allows gas to pass through it and prevents passage of liquid water and/or aqueous fuel solution.
    Type: Grant
    Filed: April 21, 2010
    Date of Patent: May 31, 2011
    Assignee: Tel-Aviv University Future Technology Development L.P.
    Inventors: Emanuel Peled, Tair Duvdevani, Arnon Blum, Vladimir Livshits, Adi Aharon
