Abstract
Methods for fabricating an interconnect for a fuel cell stack include placing a compressed metal powder interconnect on a porous support, and sintering the interconnect in the presence of a non-oxidizing gas. The method may further include placing the sintered interconnect on a porous support, and oxidizing the interconnect in the presence of flowing air, or placing the sintered interconnect on a dense, non-porous support, and oxidizing the interconnect in the presence of a gas comprising pure oxygen or an oxygen/inert gas mixture that is substantially nitrogen-free.
