  • Aqueous ionomeric gels and products and methods related thereto
    Publication number: 20060260935
    Abstract: An aqueous ionomer gel having a high viscosity, particularly a proton conducting ionomer, as well as to related products incorporating such gels. Such aqueous ionomer gels are suitable for suspending catalysts for formation of catalyst inks, which in turn are suitable for screen printing on a variety of surfaces. Representative surfaces are the electrode or membrane surfaces in an electrochemical fuel cell. Methods for making aqueous ionomer gels are also disclosed.
    Type: Application
    Filed: May 11, 2006
    Publication date: November 23, 2006
    Inventors: Wesley Gervais, Michael Lauritzen, Kristi Zychowka, Lawrence Vanderark, Kevin Colbow
