    Abstract: Electrochemical cell electrode (100) comprising a nanostructured catalyst support layer (102) having first and second generally opposed major sides (103,104). The first side (103) comprises nanostructured elements (106) comprising support whiskers (108) projecting away from the first side (103). The support whiskers (108) have a first nanoscopic electrocatalyst layer (110) thereon, and a second nanoscopic electrocatalyst layer (112) on the second side (104) comprising a precious metal alloy. Electrochemical cell electrodes (100) described herein are useful, for example, as a fuel cell catalyst electrode for a fuel cell.

    Abstract: 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.
