Embodiments of the present invention provide a method of making an interconnect comprising a) connecting a metallic material to at least a portion of a ferritic stainless steel, the metallic material being nickel or a nickel alloy, copper or a copper alloy, or a nickel-copper alloy, and b) forming an interconnect from the ferritic stainless steel. The invention further provides a method of making an interconnect comprising a) forming an interconnect from a ferritic stainless steel sheet material, the interconnect having a fuel side and an oxidant side opposite the fuel side, each of the oxidant side and the fuel side comprising a via and a gas flow channel, and b) selectively electropolishing at least a portion of at least one gas flow channel of the oxidant side of the interconnect. The invention further provides a method of making an interconnect comprising a) forming an interconnect from a ferritic stainless steel, the interconnect comprising a via and a gas flow channel, b) electropolishing at least a portion of the oxidant side of the interconnect, and c) physically or chemically removing material from at least one electropolished surface of at least one via of the oxidant side of the interconnect. |
