Publication number: 20160149230Abstract: Processes for forming films comprising multiple layers of nanostructured support elements are described. A first layer of nanostructured support elements is formed by depositing a base material on a substrate and annealing. Further growth of the first layer of nanostructures is then inhibited. Additional layers of nanostructured support elements may be grown on the first layer of nanostructures through additional deposition and annealing steps. The multilayer films provide increased surface area and are particularly useful in devices where catalyst activity is related to the surface area available to support catalyst particles.Type: ApplicationFiled: January 21, 2016Publication date: May 26, 2016Inventors: Mark K. Debe, Raymond J. Ziegler, Susan M. Hendricks

Patent number: 6613106Abstract: Membrane electrode assemblies are described that include an ion conductive membrane a catalyst adjacent to the major surfaces of the ion conductive membrane and a porous particle filled polymer membrane adjacent to the ion conductive membrane. The catalyst can be disposed on the major surfaces of the ion conductive membrane. Preferably, the catalyst is disposed in nanostructures. The polymer film serving as the electrode backing layer preferably is processed by heating the particle loaded porous film to a temperature within about 20 degrees of the melting point of the polymer to decrease the Gurley value and the electrical resistivity. The MEAs can be produced in a continuous roll process. The MEAs can be used to produce fuel cells, electrolyzers and electrochemical reactors.Type: GrantFiled: November 13, 2000Date of Patent: September 2, 2003Assignee: 3M Innovative Properties CompanyInventors: Mark K. Debe, James M. Larson, William V. Balsimo, Andrew J. Steinbach, Raymond J. Ziegler
