Abstract: Methods and systems for oxidizing an interconnect for a fuel cell stack include introducing at least one interconnect to an oxidizing gas containing water vapor, the oxidizing gas being at least substantially free of nitrogen, and oxidizing the at least one interconnect in the presence of the oxidizing gas at an elevated temperature. The oxidation may be performed at a sub-atmospheric pressure. The oxidation of the interconnect may be a controlled oxidation that is performed prior to incorporating the interconnect into a fuel cell stack.
