Abstract: A system and method in which a high temperature fuel cell stack exhaust stream is recycled back into the fuel inlet stream of the high temperature fuel cell stack. The recycled stream may be sent to a carbon dioxide separator that separates carbon dioxide from the fuel exhaust stream. The carbon dioxide separator may include a carbon dioxide separation membrane, an oxygen blocking membrane, and a water blocking membrane.

Abstract: A method of making an interconnect for a solid oxide fuel cell stack includes providing a chromium alloy interconnect and providing a nickel mesh in contact with a fuel side of the interconnect. Formation of a chromium oxide layer is reduced or avoided in locations between the nickel mesh and the fuel side of the interconnect. A Cr—Ni alloy or a Cr—Fe—Ni alloy is located at least in the fuel side of the interconnect under the nickel mesh.

Abstract: A fuel cell interconnect includes fuel ribs disposed on a first side of the interconnect and a least partially defining fuel channels, and air ribs disposed on an opposing second side of the interconnect and at least partially defining air channels. The fuel channels include central fuel channels disposed in a central fuel field and peripheral fuel channels disposed in peripheral fuel fields disposed on opposing sides of the central fuel field. The air channels include central air channels disposed in a central air field and peripheral air channels disposed in peripheral air fields disposed on opposing sides of the central air field. At least one of the central fuel channels or the central air channels has at least one of a different cross-sectional area or length than at least one of the respective peripheral fuel channels or the respective peripheral air channels.
