Title (EN) ELECTRODE CATALYST FOR FUEL CELL, METHOD OF PRODUCING THE SAME, AND FUEL CELL
(FR) CATALYSEUR D'ÉLECTRODE POUR PILE À COMBUSTIBLE, SON PROCÉDÉ DE PRODUCTION, ET PILE À COMBUSTIBLE
Abstract: front page image
(EN) The present invention relates to an electrode catalyst for a fuel cell that includes a carbon support (11) having pores (13) and catalyst particles containing platinum or a platinum alloy supported on the carbon support (11). The pores (13) of the carbon support (11) have a mode size of pores (13) in a range of 2.1 nm to 5.1 nm. A total pore volume of the pores (13) of the carbon support (11) is in a range of 21 cm3/g to 35 cm3/g. A distance between the catalyst particles and a surface of the carbon support (11) is in a range of 2.0 nm to 12 nm as a distance of a 50% cumulative frequency.
(FR) La présente invention concerne un catalyseur d'électrode pour une pile à combustible qui comprend un support carboné (11) ayant des pores (13) et des particules de catalyseur contenant du platine ou un alliage de platine supportées sur le support carboné (11). Les pores (13) du support carboné (11) présentent une valeur modale de taille de pores (13) située dans une plage allant de 2,1 nm à 5,1 nm. Un volume poreux total des pores (13) du support carboné (11) est situé dans une plage allant de 21 cm3/g à 35 cm3/g. Une distance entre les particules de catalyseur et une surface du support carboné (11) est située dans une plage allant de 2,0 nm à 12 nm en tant que distance d'une fréquence cumulée de 50 %.
