    摘要: A stainless steel for use in a fuel cell separator is produced by subjecting stainless steel containing 16 mass % or more of Cr to electrolytic treatment and thereafter to immersion treatment in a solution containing fluorine. The electrolytic treatment is carried out by anodic electrolyzation or by a combination of anodic electrolyzation and cathodic electrolyzation, and an anodic electrolytic quantity Qa and a cathodic electrolytic quantity Qc preferably satisfy Qa≧Qc. The solution containing fluorine preferably has a temperature of 40° C. or higher, and hydrofluoric acid concentration [HF] (mass %) and nitric acid concentration [HNO3] (mass %) satisfying [HF]≧0.8×[HNO3].

    摘要: An object is to provide at a low cost a metal sheet which can be ideally used as a separator of a proton-exchange membrane fuel cell and which has not only low contact resistance but also excellent durability in the environment in which the separator is used. Specifically, a metal sheet for a separator of a proton-exchange membrane fuel cell consists of a metal substrate on the surface of which a film made of a Sn alloy layer containing conducting particles is formed.

    摘要: A ferritic stainless steel plate of excellent ridging resistance and formability, as well as a manufacturing method thereof are proposed. Specifically, the rolling is conducted at a rolling reduction of 30% or more in at least 1 pass and at a temperature difference between the center of the plate thickness and the surface of 200° C. or lower in a pass for the maximum rolling reduction to cause the area ratio of a {111} orientation colony to be present by 30% or more in the regions of ⅛ to ⅜ and ⅝ to ⅞ of the plate thickness. The {111} orientation colony is an assembly of adjacent crystals in which the angle of orientation vector for each of the crystals relative to the direction vector vertical to the rolling surface is within 15°.
