Abstract: A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. When the matrix of the thin plate is crystal-structure metal, the plate can be formed at room temperature, and when the matrix is metallic glass, the plate can be formed in a supercooled liquid state. Therefore the plate can be finished into a separator with an intended shape.

Abstract: A full enclosed forging apparatus comprising a construction in which an upper die holder and a lower die holder are respectively disposed as to face a press machine, at least one of the upper die holder and the lower die holder is composed of a holder main body holding a die and a holder base attached to the press machine, and the holder main body is attached to the holder base through plural spring mechanisms with an aperture as an interference of the spring mechanisms as that an upper punch proceeds into the upper die and a lower punch proceeds into the lower die after the upper die held by the upper die holder and the lower die held by the lower die holder contact.
