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.
