A solid oxide fuel cell (SOFC) includes a plurality of sub-cells. Each sub-cell includes a first electrode in fluid communication with a source of oxygen gas, a second electrode in fluid communication with a source of a fuel gas, and a solid electrolyte between the first electrode and the second electrode. The SOFC further includes an interconnect between the sub-cells. The interconnect includes a first layer in contact with the first electrode of each sub-cell, and a second layer in contact with the second electrode of each sub-cell. The first layer includes at least one material selected from the group consisting of a doped M-ferrite based perovskite, a doped M'-ferrite based perovskite, a doped MM'-ferrite based perovskite and a doped M'-chromite based perovskite, wherein M is an alkaline earth metal and M' is a rare earth metal. The second layer includes a doped M''-titanate based perovskite, wherein M'' is an alkaline earth metal. A solid oxide fuel cell having a plurality of cells as described above is formed by connecting each of a plurality of sub-cells with an interconnect as described above. |
