Denise M. Katona has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multilayered composite proton exchange membrane and a process for manufacturing the same
    Patent number: 9023553
    Abstract: A multilayered membrane for use with fuel cells and related applications. The multilayered membrane includes a carrier film, at least one layer of an undoped conductive polymer electrolyte material applied onto the carrier film, and at least one layer of a conductive polymer electrolyte material applied onto the adjacent layer of polymer electrolyte material. Each layer of conductive polymer electrolyte material is doped with a plurality of nanoparticles. Each layer of undoped electrolyte material and doped electrolyte material may be applied in an alternating configuration, or alternatively, adjacent layers of doped conductive polymer electrolyte material is employed.
    Type: Grant
    Filed: September 3, 2008
    Date of Patent: May 5, 2015
    Assignee: Chemsultants International, Inc.
    Inventors: Pasco R. Santurri, James H. Duvall, Denise M. Katona, Joseph T. Mausar, Berryinne Decker
