Abstract:
(EN) The present invention provides an electrically conductive material having high conductivity and excellent resistance to high electric potential and strongly acidic environments, and an electrode material and fuel cell using the electrically conductive material. The present invention also provides a method for simply and easily obtaining such an electrically conductive material. The electrically conductive material according to the present invention comprises titanium suboxide powder, wherein the titanium suboxide powder has a composition represented by TiOn (n represents a value of 1.5-1.90), a rutile crystal phase as the main phase, and a lightness L* of 35-45 in the L*a*b* color system.
(FR) La présente invention concerne un matériau électroconducteur présentant une conductivité élevée et une excellente résistance à un potentiel électrique élevé et à des environnements fortement acides, et un matériau d'électrode et une pile à combustible utilisant le matériau électroconducteur. La présente invention concerne également un procédé permettant d'obtenir de manière simple et facile un tel matériau électroconducteur. Le matériau électroconducteur selon la présente invention comprend de la poudre de sous-oxyde de titane, ladite poudre de sous-oxyde de titane ayant une composition représentée par TiOn (n représente une valeur de 1,5 à 1,90), une phase cristalline rutile en tant que phase principale, et une luminosité L* de 35 à 45 dans le système couleur L*a*b*.
