Abstract:
A method of forming a fuel cell interconnect includes depositing a Cr alloy powder, sintering the Cr alloy powder, and repeating the depositing and the sintering to form the fuel cell interconnect. The Cr alloy powder may include a pre-alloyed powder containing from about 4 wt. % to about 6 wt. % Fe, and from about 94 wt. % to about 96 wt. % Cr.
