TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Device: The tubes and support are an integrally molded structure, the tubes positioned in an array of columns and rows. The electrolyte has vias formed in an array of columns and rows adjacent and corresponding to the tubes.First and second conductive coatings cover the exterior (exterior surface of the tubes) and interior (interior surface of the tubes, each interior surface being electrically isolated from each other) of the respective elements, and are connectable to first and second polarity electric potentials respectively. The vias are also covered with an electroconductive coating which connects the coating on one column of tubes with that on an adjacent column of tubes. Plugs are inserted into the vias.    TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Element: An electrode coating of La1-xAxMnO3 is formed on the inner and outer surfaces of the electrolyte element, and is especially a coating of La1-xSrxCo1-yMnO3Fey;x = 0.0-1.00;A = Sr, Ca or Ba.A current collector coating of Au, Pd, Pt or their alloys is formed on the electrode coating.The electrolyte itself consists of Zr1-xAxO2, Ce1-xAxO2, (Bi2O3)1-x(A2O3), Bi2V1-xAxO5.5-3x/2 or La1-xSrxGa1-yMgyO3 or their mixtures together with a binder for use during injection molding.x, y = each 0-0.30;A = Y, Yb, Sc, Ca, Mg, Sm, Gd, La, Sr, Nd, Er, Dy, Cu, Ti, Zr, Al, Co or Ni,The seal is a ceramic loaded cement, and the seal chamber is capable of holding 2000 psi.    TECHNOLOGY FOCUS - POLYMERS - Preferred Binder: The binder is 0-75 vol% of a polymer selected from polystyrene, polyethylene, polypropylene, ethylene vinyl acetate, polyvinyl alcohol, polyethylene glycol, polyethylene chlorate, polyvinyl chlorate and polyacetal, 0-75 vol% of a wax selected from paraffin, micro crystalline, carnauba and beeswax, 0-75 vol% of an oil selected from peanut, vegetable and mineral, 0-20 vol% of an acid selected from stearic, oleic and boric, at most 10 vol% agar, at most 10 vol% glycerin, at most 80 vol% water, or 5-30 vol% methyl cellulose. EXAMPLE - None Given.
