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.
