Abstract: Methods for deoxidizing metallic surfaces are disclosed. Such a method may include contacting a surface of a metal strip with one or more chemical solutions until a potential drop across a thickness of the metal strip is less than a pre-selected value. To process a metal strip such that it may be suitable for fabrication of a bipolar plate for use in a fuel cell, the metal strip may be processed until the potential drop is less then about 15 mV. A surface of the metal strip may be contacted for a first period of time with a first chemical solution having a pH of between 10 and 14. Thereafter, the surface may be contacted for a second period of time with a second chemical solution having a pH of between 1 and 3. A conductive organic coating may then be applied to the surface. Such methods are particularly suitable for use in connection with a coil coating process.
