    摘要: The gas 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 for coating the substrate portion and the underlying coating layer, and a second coating layer formed thereon. The second coating layer is formed from a carbon material, and is sufficiently conductive. Moreover, the second coating layer protects the underlying layer. 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.

    摘要: 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.

    摘要: A manufacturing method of a multi-laminated body according to the present invention includes a step 1 (L-flow path) for vertically dividing a laminated flow obtained by arranging at least two molten resins adjacent to each other in a lengthwise direction into two sections, guiding the divided laminated flows to opposite directions relative to the flow direction, and then guiding both laminated flows toward the center of the flow direction, and rearranging the laminated flows adjacent to each other in the horizontal direction and thereby joining the laminated flows together, and a step 2 (R-flow path) for vertically dividing a laminated flow obtained by arranging at least two molten resins adjacent to each other in a lengthwise direction into two sections, guiding the divided laminated flows to directions opposite to the above-mentioned directions relative to the flow direction, and then guiding both laminated flows toward the center of the flow direction, and rearranging the laminated flows adjacent to each other in the horizontal direction and thereby joining the laminated flows together, in which the step 1 (L-flow path) and the step 1 (R-flow path) are alternately repeated in this listed order, and a number of the steps to be performed is at least three. According to this method, it is possible to prevent the layer disappearance at both ends, prevent the layer thickness variations or the disruption in the lengthwise arrangement, and thereby manufacture a multi-laminated body having a more excellent uniformity.

    摘要: 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.
