CA 2584637

A flooding phenomenon in a high current density loading region of fuel cells is suppressed so as to improve cell performance. An electrode catalyst for fuel cells comprises conductive carriers having ternary catalyst particles, which contain platinum, a base metal element, and iridium, supported thereon. A fuel cell uses the electrode catalyst for fuel cells.

Un phénomène d'engorgement dans une région de charge à haute densité de courant de piles à combustible est supprimé de manière à améliorer le rendement d'une pile. L'invention concerne un catalyseur d'électrode pour piles à combustible comprenant des supports conducteurs présentant des particules de catalyseur ternaire renfermant du platine, un élément métallique de base et de l'iridium fixés sur le support. L'invention concerne en outre une pile à combustible utilisant le catalyseur d'électrode pour piles à combustible.
