NOVELTY - The process comprises anodizing a conductive metal plate to form a corrosion resistant surface layer having a water contact angle of less than 40 degrees , and depositing a conductive layer above the corrosion resistant surface layer using atomic layer deposition method. The atomic layer deposition method is carried out for a long gas pulse time of 10-30 seconds. The conductive metal plate has a fuel cell reactant gas channel for fluid passage. The metal plate is exposed to a gas pulse comprising metal compound vapor so that an atomic layer of the metal compound is adsorbed on the surface.    USE - The process is useful for producing a fuel cell bipolar plate, which is useful in a product (claimed)such as a fuel cell stack.    ADVANTAGE - The process is capable of effectively and easily producing low-cost and light weight fuel cell bipolar plate with excellent corrosion resistance, low electric contact resistance and good water management properties.    DETAILED DESCRIPTION - The process comprises anodizing a conductive metal plate to form a corrosion resistant surface layer having a water contact angle of less than 40 degrees , and depositing a conductive layer above the corrosion resistant surface layer using atomic layer deposition method. The atomic layer deposition method is carried out for a long gas pulse time of 10-30 seconds. The conductive metal plate has a fuel cell reactant gas channel for fluid passage. The metal plate is exposed to a gas pulse comprising metal compound vapor so that an atomic layer of the metal compound is adsorbed on the surface of the metal plate. The deposition chamber is purged with an inert gas to remove the metal compound residue vapor. After the metal compound is adsorbed on the metal plate, the metal plate is exposed to a gas pulse comprising oxygen compound and nitrogen compound at 100-600 degrees C causing the adsorbed metal compound to react with the oxygen compound and nitrogen compound to form a metal oxynitride. INDEPENDENT CLAIMS are included for:    (1) a fuel cell bipolar plate; and    (2) a product of a fuel cell stack.
