Abstract: The invention relates to a method of making fuel cell devices. Anode and cathode layers are applied on respective first and opposing second sides of a first portion of a first green ceramic layer, and a second green ceramic layer of thickness approximately equal to that of the anode and cathode layers is applied on a second portion of each of the first and second sides of the first green ceramic layer. A sacrificial layer is applied over each of the anode, cathode and second green ceramic layers, and a third green ceramic layer is applied over the sacrificial layers. The layered structure is heated to sinter all the layers and burn out the sacrificial layers. A pair of gas passages is thus formed with a thick sintered ceramic therebetween as a passive supporting portion and an anode, thin electrolyte and cathode therebetween as an active portion of the device.

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.
