(FR) CATALYSEUR D'ÉLECTRODE POSITIVE POUR ACCUMULATEUR MÉTAL-AIR ET ACCUMULATEUR MÉTAL-AIR
(JA) 金属空気電池用正極触媒及び金属空気電池
Abstract:
(EN) Provided is a positive-electrode catalyst which has excellent durability and excellent activity in the environment in which a metal-air battery is operated. The positive-electrode catalyst for a metal-air battery according to the present invention includes a melilite composite oxide represented by general formula (BazSr1-z)2CoxFe2-2x(SiyGe1-y)1+xO7 (in the formula, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, and 0 ≤ z ≤ 1).
(FR) L'invention concerne un catalyseur d'électrode positive qui présente une excellente durabilité et une excellente activité dans l'environnement de fonctionnement d'un accumulateur métal-air. Le catalyseur d'électrode positive pour un accumulateur métal-air selon la présente invention comprend un oxyde composite de mélilite représenté par la formule générale (BazSr1-z)2CoxFe2-2x(SiyGe1-y)1+xO7 (dans la formule, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, et 0 ≤ z ≤ 1).
(JA) 金属空気電池の動作環境下において、耐久性や活性に優れる正極触媒を提供すること。 本発明に係る金属空気電池用正極触媒は、一般式(BaSr1-zCoFe2-2x(SiGe1-y1+x(式中、0≦x≦1,0≦y≦1,0≦z≦1)で表されるメリライト型複合酸化物を備える。
