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.

[Problem] To prepare a thin plate having excellent corrosion resistance, conductivity, and formability at low cost. [Solution] 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. An obtained thin plate has a conductive material component that exists, without dissolving, in a metal matrix exhibiting corrosion resistance by passivation, thereby having aforementioned characteristics.

An apparatus for forming an amorphous coating film by jetting flame containing particles of a flame spray material from a flame spray gun toward a base material, causing the particles to be melted by the flame, and cooling both the particles and the flame with the means of a cooling gas before they reach the base material. The apparatus includes a tubular member provided among the path along which the flame is jetted that it surrounds the flame passing through a melting zone in which the particles are melted. The tubular member has a flow channel for the cooling gas, formed along and integrally to the tubular member.
