Abstract: A method of fabricating a ceramic tube with electrodes thereon suitable for use as a tubular reaction chamber for a fuel cell. In one embodiment, the method includes wrapping a first electrode material around a mandrel, then wrapping a green ceramic material over the first electrode material, and then wrapping a second electrode material over the green ceramic material. The wrapped layers are laminated together, and then removed from the mandrel and sintered, in either sequence, to produce the laminated ceramic tube having an inner first electrode and an outer second electrode. Alternatively, a first electrode tube is provided in place of the mandrel and around which the green ceramic material is wrapped. The outer second electrode may be produced by wrapping a second electrode material around the green ceramic material, before or after laminating, or by printing the electrode material onto the sintered ceramic tube. The present invention further provides a method of making a ceramic tube in which a sacrificial organic material is first wrapped around the mandrel to a desired thickness prior to wrapping the green ceramic material to increase the green material thickness. During sintering, the organic material is burned away leaving only a laminated ceramic tube, optionally with electrodes thereon.

Abstract: A fuel cell device is prepared by dispensing and drying electrode and ceramic pastes around two pluralities of removable physical structures to form electrode layers having constant width and a shape that conforms lengthwise to a curvature of the physical structures. An electrolyte ceramic layer is positioned between electrode layers, forming an active cell portion where anode is in opposing relation to cathode with electrolyte therebetween, and passive cell portions where ceramic is adjacent the active cell portion. The layers are laminated, the physical structures pulled out, and the lamination sintered to form an active cell with active passages in anodes and cathodes and passive support structure with passive passages in ceramic. End portions of at least one of the two pluralities of physical structures are curved away from the same end portion of the other of the two pluralities resulting in a split end in the fuel cell device.

Abstract: Fuel cell devices and systems are provided. In certain embodiments, the devices include a ceramic support structure having a length, a width, and a thickness with the length direction being the dominant direction of thermal expansion. A reaction zone having at least one active layer therein is spaced from the first end and includes first and second opposing electrodes, associated active first and second gas passages, and electrolyte. The active first gas passage includes sub-passages extending in the y direction and spaced apart in the x direction. An artery flow passage extends from the first end along the length and into the reaction zone and is fluidicly coupled to the sub-passages of the active first gas passage. The thickness of the artery flow passage is greater than the thickness of the sub-passages. In other embodiments, fuel cell devices include second sub-passages for the active second gas passage and a second artery flow passage coupled thereto, and extending from either the first end or the second end into the reaction zone. In yet other embodiments, one or both electrodes of a fuel cell device are segmented.

Abstract: A fuel cell device with a rectangular solid ceramic substrate extending in length between first and second end surfaces where thermal expansion occurs primarily along the length. An active structure internal to the exterior surface extends along only a first portion of the length and has an anode, cathode and electrolyte therebetween. The first portion is heated to generate a fuel cell reaction. A remaining portion of the length is a non-heated, non-active section lacking opposing anode and cathode where heat dissipates along the remaining portion away from the first portion. A second portion of the length in the remaining portion is distanced away from the first portion such that its exterior surface is at low temperature when the first portion is heated. The anode and cathode have electrical pathways extending from the internal active structure to the exterior surface in the second portion for electrical connection at low temperature.

At least three elongate portions extend from the active central portion, each having a length substantially greater than a width transverse thereto such that the elongate portions each have a coefficient of thermal expansion having a dominant axis that is coextensive with its length. A fuel passage extends from a fuel inlet in a first elongate portion into the active central portion in association with the anode, and an oxidizer passage extends from an oxidizer inlet in a second elongate portion into the active central portion in association with the cathode.

Abstract: A fuel cell device having an exterior surface defining an interior ceramic support structure. An active zone is along an intermediate portion of the length for undergoing a fuel cell reaction, and opposing non-active end regions are along end portions extending away from the active zone without being heated. Fuel and oxidizer passages extend within the interior support structure from respective first and second inlets in respective ones of the opposing non-active end regions. The active zone has an anode associated with each of the fuel passages and a cathode associated with each of the oxidizer passages in opposing relation to a respective one of the anodes with an electrolyte therebetween. The opposing non-active end regions lack the anode and cathode in opposing relation so as to be incapable of undergoing a fuel cell reaction.
