Patent

CA 2304157

Nanostructured elements are provided for use in the electrode of a membrane electrode assembly for use in fuel cells, sensors, electrochemical cells, and the like. The nanostructured elements comprise acicular microstructured support whiskers bearing acicular nanoscopic catalyst particles which may comprise alternating layers of catalyst materials, which may comprise a surface layer that differs in composition from the bulk composition of the catalyst particles, and which may demonstrate improved carbon monoxide tolerance.

Cette invention se rapporte à des éléments nanostructurés servant à constituer l'électrode d'un ensemble électrode à membrane utilisé dans des piles à combustible, des capteurs, des cellules électrochimiques et similaires. Ces éléments nanostructurés comprennent des filaments de support microstructurés aciculaires, portant des particules catalytiques nanoscopiques aciculaires, qui peuvent comporter des couches alternées de matériaux catalytiques, pouvant être constituées par une couche de surface dont la composition diffère de la composition de la masse des particules catalytiques, et qui peuvent présenter une tolérance accrue au monoxyde de carbone.
