摘要： The present invention provides a production method for a metal separator plate for a fuel cell which can maintain superior electrical conductivity and corrosion resistance without other adverse effects not just initially but even when used for an extended period of time under operating conditions involving severe vibration such as in a vehicle, which allows continuous production processing, and which allows high production efficiency. The production method for a metal separator plate for a fuel cell of the present invention is characterised in that it comprises: (a) a stage in which a base material made of a metal plate is made ready; (b) a stage in which the surface of the metal plate is subjected to acid cleaning; (c) a stage in which the surface of the acid-cleaned metal plate is coated with a composition comprising a binder resin, carbon particles and a solvent; and (d) a stage in which the metal plate, whose surface has been coated with the said composition, is dried at a temperature lower than the thermal decomposition temperature of the binder resin and higher than the boiling point of the solvent, and in which a coating layer, comprising carbon particles dispersed in a binder resin matrix, is formed on the surface of the metal plate; and these processes are carried out in a continuous process.
