Summary: | The purpose of the present invention is to provide a catalyst which has excellent activity in oxygen reduction reaction. This catalyst comprises a catalyst support and a catalyst metal supported on the catalyst support, wherein the catalyst has a specific surface area of 715 m2 or greater per g of the support or the degree of coverage of the catalyst metal by an electrolyte is less than 0.5, and wherein the catalyst contains acidic groups in an amount of 0.75 mmol or less per g of the support.
L'objet de la présente invention est de fournir un catalyseur qui présente une excellente activité dans la réaction de réduction de l'oxygène. Ledit catalyseur comprend un support de catalyseur et un métal catalyseur supporté sur le support de catalyseur, le catalyseur ayant une surface spécifique supérieure ou égale à 715 m2 par g du support ou le degré de couverture du métal catalyseur par un électrolyte est inférieur à 0,5, et le catalyseur contenant des groupes acides en proportion inférieure ou égale à 0,75 mmol par g du support. |
