Further, there is provided a second method for producing a stainless steel three-ply clad sheet for a fuel cell separator, comprising heating the source blank produced by the first method and then performing rough rolling, hot rolling and cold rolling thereto, whereby the clad steel sheet for the fuel cell separator or a solid polymer type fuel cell separator thereby is obtained. According to this, a source blank for a stainless steel three-ply clad sheet and a separator steel sheet, including B-containing steel as a face layer, which are most suitably used as a solid polymer type fuel cell separator can be provided.

摘要： A stainless steel having excellent corrosion resistance to ozone added water, such as ozone added ultrapure water used in semiconductor manufacturing processes and the like, as well as a manufacturing method. The stainless steel comprises a base metal and an oxide film formed on the surface of the base metal, the base metal being a stainless steel which contains 12 to 30% of Cr, 0 to 35% of Ni, and 1 to 6% of Al and Si while the contents of the other alloying elements are limited to as low a level as possible, the oxide film mainly comprising Al oxide or a Si oxide or both. The oxide film may be formed on the base metal surface through the dry oxidation process or the wet oxidation process. In the stainless steel, metallic ions are rarely dissolved from the base metal into the ozone added water. Also, since the contents of alloying elements, other than Cr, Ni, Al, Si, and like necessary elements, are limited to a low level, the stainless steel exhibits excellent corrosion resistance and reduced particle emission.

摘要： A separator material effective for decreasing the weight of fuel cells is provided which is lightweight, has good corrosion resistance, and exhibits a minimized increase in electrical contact resistance during use for a long period. Titanium or a titanium alloy is prepared by melting so as to contain not greater than 5 mass % B, thereby forming a titanium-based material in which fine TiB-type boride particles are precipitated and dispersed. The material is then etched in an aqueous acidic solution such that some of the TiB-type boride particles are exposed on the surface through the passive film formed thereon.
