Abstract:
A system for oxygen generation, comprising:(a) a plurality of cells arranged to form a stack of cells, each said cell comprising an electrolyte composed of BICUVOX having the formula Bi.sub.2 V.sub.0.9 Cu.sub.0.1 O.sub.5.35, said electrolyte comprising a thin square plate, and a pair of electrodes placed in electrical contact with said BICUVOX electrolyte so as to produce a flow of oxygen ions therethrough, said electrodes comprising square plates having gas flow channels formed on each side in contact with said BICUVOX electrolyte plate, said channels being oriented such that oxygen flow and oxygen-depleted gas flow may be separated, said BICUVOX electrolytes and said electrodes have common lengths and widths; and(b) a tubular manifold enclosing said stack of cells wherein the diameter of said manifold is slightly larger than the common diagonal length of said plates and wherein said stack is sealed at its four corners to the inside surface of said manifold thereby creating between the sides of said cell and the inside surface of said manifold a first passage for oxygen-containing gas flow, a second passage for oxygen-depleted gas flow, and third and fourth passages for oxygen gas flow, said flow passages being separated from each other.
