CA 2430666

A separator of a fuel cell includes a base material and a surface treatment layer formed on the base material. The surface treatment layer includes a base material-side portion made from metal and a base material opposite-side portion made from carbon formed at an atom level or composite materials of carbon and metal or semi- metal. The surface treatment layer may further include carbon particle composite layer formed on the base material opposite-side portion formed at an atom level. In a manufacturing method of the above separator of a fuel cell, the base material opposite-side portion is formed by dry coating.

Un séparateur de pile à combustible comprend un matériau de base et une couche de traitement de surface formée sur le matériau de base. La couche de traitement de surface inclut une portion latérale du matériau de base faite de métal et une portion du côté opposé du matériau de base faite de carbone formé au niveau de l'atome ou un matériau composite de carbone et de métal ou de semi-métal. La couche de traitement de surface peut aussi inclure une couche composite en particules de carbone formé sur la portion du côté opposé du matériau de base formée au niveau de l'atome. Dans la méthode de fabrication du séparateur de pile à combustible susmentionnée, la portion du côté opposé du matériau de base est formée par enduit sec.
