摘要： PROBLEM TO BE SOLVED: To realize sufficient corrosion resistance in metallic gas separator. SOLUTION: The separator 30 is equipped with a substrate 60, ground coat layers 62 provided thereon, the first coating layers 64 covering these, and the second coat layers 66 further provided thereon. The second coating layers 66 are constituted with carbon material, and have a sufficient electroconductivity and protect the lower layers as well. The first coating layers 64 are made of a low melting-point metal and formed by applying molten processing to this low melting-point metal. What is meant by the molten processing is a method that the object is once heated to a temperature at which the low melting-point metal melts but the substrate 60 or the ground coating layer 62 does not, followed by cooling again. With this procedure, crystal grains of the metal becomes larger and the grain boundary density smaller in the first coating layer 64.

摘要： PROBLEM TO BE SOLVED: To provide a male forming method which restricts droop and deformation of a forming goods. SOLUTION: An outer circumference frame 2 is attached to the circumference edge part 2 of a base plate 1, and a supporting tool 3 is mounted on the central part of the base plate 1. Further, a metal sheet 4 is held on the upper face of the outer circumference frame 2 with bolts 10 so that the metal sheet 4 is brought into contact with the peak of the supporting tool 3. A set of jigs in this state is fixed on a table of an NC vertical milling machine. Next, based on a forming contour data assembled with a male die working contour data and a circumference working contour data, a tool 5 is moved so as to alternately repeat circumference forming and male die forming, the metal sheet 4 supported with the supporting tool 3 is formed with pressing from the upper side by every one layer or every plural layers, and formed into the male die shape. In this time, the tool 5 is always moved from the range of outskirts of the outer circumference frame 2 toward the center.

摘要： PROBLEM TO BE SOLVED: To provide a separator for fuel cell that is of low cost and has excellent conductivity, and is superior in durability and corrosion resistance, and a method of manufacturing the separator simply and easily. SOLUTION: The separator, which is used for a solid polymer fuel cell, is made by a base material by forming an iron based material having a carbon content of 0.1 wt.% or more and 1 wt.% or less and by forming a carbide coated on the surface of the base material by TRD treatment. The separator is made which has a good property demonstrating the characteristics of the carbide coating by TRD treatment. And the base material is formed by press molding and then it undergoes the TRD treatment, and, then, distortion is eliminated. Since the thermal distortion due to the TRD treatment is eliminated, a separator having a stable configuration is manufactured simply and easily.
