ELECTROCHEMICAL CELL ELECTRODE

摘要

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.
