Abstract:
(EN) [Problem] To provide: a carbon powder which is capable of providing a catalyst that exhibits high performance; and a catalyst. [Solution] A carbon powder for fuel cells, which is mainly composed of carbon, and wherein if A is the area of a peak 0 that is present at the position of 2θ=22.5°-25° as observed by XRD analysis and B is the area of a peak 1 that is present at the position of 2θ=26° as observed by XRD analysis when the carbon powder for fuel cells is subjected to a heat treatment at 1,800°C for one hour in an inert atmosphere, the ratio of the area B of the peak 1 to the area A of the peak 0, namely B/A is more than 0 but 0.15 or less.
(FR) Le problème décrit par la présente invention est de fournir : une poudre de carbone qui est capable de fournir un catalyseur qui présente une performance élevée ; et un catalyseur. La solution selon l’invention porte sur une poudre de carbone pour piles à combustible, qui est principalement composée de carbone, et où si A est la surface d'un pic 0 qui est présent à la position de 2θ = 22,5° à 25° telle qu'observée par analyse de diffraction par rayons X et B est la surface d'un pic 1 qui est présent à la position de 2θ = 26° telle qu'observée par analyse de diffraction par rayons X lorsque la poudre de carbone pour piles à combustible est soumise à un traitement thermique à 1 800 °C pendant une heure dans une atmosphère inerte, le rapport de la surface B du pic 1 à la surface A du pic 0, à savoir B/A, est supérieur à 0 mais inférieur à 0,15.
(JA) 【課題】高い性能を有する触媒を提供できる炭素粉末および触媒を提供する。 【解決手段】炭素を主成分とする燃料電池用炭素粉末であって、不活性雰囲気中で1800℃で1時間熱処理した際のXRD分析によって観測される2θ=22.5°~25°の位置に存在するピーク0の面積をA、XRD分析によって観測される2θ=26°の位置に存在するピーク1の面積をBとした場合、ピーク0の面積Aに対するピーク1の面積Bの比(B/A)が0を超えて0.15以下である、燃料電池用炭素粉末。
