Abstract
Described herein are new solid oxide fuel cell interconnects and methods for making same that may comprise a novel bilayer construct on an anode substrate to provide a dense microstructure, low area specific resistance, and negligible oxygen permeability to form a bilayer ceramic interconnect that is a strong candidate for next-generation, durable, and low-cost tubular solid oxide fuel cells.
