Abstract

The vapor deposition methods of planar magnetron sputtering and electron-beam evaporation are used to synthesize materials with nanostructured morphological features that have ultra-high surface areas with continuous open porosity at the nanoscale. These nanostructured membranes are used in a variety of fuel cells to provide electrode and catalytic functions. Specifically, stand alone and composite nickel electrodes for use in thin film solid-oxide, and molten carbonate fuel cells are formed by sputter deposition and electron beam evaporation, respectively. Also, a potentially high-performance catalyst material for the direct reformation of hydrocarbon fuels at low temperatures is deposited as a nanostructure by the reactive sputtering of a copper-zinc alloy using a partial pressure of oxygen at an elevated substrate temperature.
