A low-cost fuel cell separator having a metallic substrate which is able to stably maintain low electric resistance (high electrical conductivity) and high corrosion resistance for a long period is provided. The separator has a metallic substrate having an oxide film forming a surface thereof and made from an oxidization of a metal of the substrate, and an electrically conductive thin film formed on a surface of the oxide film of the substrate. Due to this construction, low electric resistance (high electrical conductivity) is achieved by the electrically conductive thin film. Furthermore, even if the electrically conductive thin film has pinholes, the oxide film substantially prevents or reduces elution from the separator substrate, thereby achieving high corrosion resistance. Still further, since the oxide film is formed by oxidation of the substrate, the oxide film can be formed at a lower cost than an oxide film formed from a different metal.

Fuel cell separator and production method therefor

A separator is provided with a substrate portion having a predetermined concave-convex shape, an underlying coating layer formed on the substrate portion, a first coating layer coating the substrate portion and the underlying coating layer, and a second coating layer formed thereon. The second coating layer, which is formed from carbon materials, is sufficiently electrically conductive and protects the underlying layers. The first coating layer is formed from a low-melting-point metal subjected to a melting process. The melting process is a process of first conducting heating at such a temperature that melts the low-melting-point metal but does not melt the substrate portion and the underlying coating layer and then conducting cooling. Thus, in the first coating layer, the crystal grain size of the metal is increased and thus the grain boundary density is reduced.

Fuel cell separator, manufacturing method thereof and fuel cell

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.

The first coating layer is formed from a noble metal. Therefore, the first coating layer coated with the second coating layer exhibits extremely high corrosion resistance. The underlying coating layer and the substrate portion are coated with the first and second coating layers, so that the progress in corrosion can be sufficiently prevented. Thus, excellent overall corrosion resistance of the separator can be realized.
