The selective dissolution of Al from the Pt-alloy compound causes the formation of a highly porous nanowire network with a mean branch thickness below 25 nm and a pore intercept length below 35 nm. The oxygen reduction capability of the resulting electrodes was analysed in a micro-solid oxide fuel cell setup at elevated temperatures (598-873 K). Here, we demonstrate that these nanoporous thin films excel \"state-of-the-art\" fuel cell electrodes in","authors_text":"Anna Evans, Barbara Scherrer, Henning Galinski, Ludwig J.
