Abstract:
The invention provides solid oxide fuel cell devices and systems, each including an elongate substrate having an active end region for heating to an operating reaction temperature, and a non-active end region that remains at a low temperature below the operating reaction temperature when the active end region is heated. An electrolyte is disposed between anodes and cathodes in the active end region, and the anodes and cathodes each have an electrical pathway extending to an exterior surface in the non-active end region for electrical connection at low temperature. The system further includes the devices positioned with their active end regions in a hot zone chamber and their non-active end regions extending outside the chamber. A heat source is coupled to the chamber to heat the active end regions to the operating reaction temperature, and fuel and air supplies are coupled to the substrates in the non-active end regions.

Claim (Index 1):
A solid oxide fuel cell device comprising:\n an elongate substrate having a length between first and second ends that is at least five times greater than the width, opposing first and second sides along the length, a non-active end region adjacent the first end, and an active end region adjacent the second end; a first multi-layer anode-cathode structure comprising a plurality of anodes in opposing relation with a plurality of cathodes within the elongate substrate in the active end region and an electrolyte disposed between each of the opposing anodes and cathodes for undergoing a fuel cell reaction when supplied with heat, fuel and oxidizer, wherein the non-active end region lacks the anodes and cathodes in opposing relation and extended length-wise away from the non-active end region without being heated to dissipate heat and to thereby remain at a lower temperature than the active end region when the active end region is supplied with heat; at least one tab portion extending from each one of the plurality of anodes and cathodes within the active end region of the elongate substrate to one of the opposing first and second sides to form electrical pathways to a respective plurality of exposed anode and cathode surfaces in the active end region; at least one first exterior metallization on one of the opposing first and second sides in contact with at least one exposed anode in the active end region and extending length-wise to the non-active end region for electrical connection at the lower temperature; at least one second exterior metallization on one of the opposing first and second sides in contact with at least one exposed cathode in the active end region and extending length-wise to the non-active end region for electrical connection at the lower temperature; and one or more third exterior metallizations on one or both of the opposing first and second sides, applied over at least one pair of adjacent exposed anode and cathode surfaces to electrically connect respective anodes and cathodes in series in the active end region.
