Abstract: An oxygen or ozone generating device having a plurality of ceramic composite cells, a resistance heat element, a cathode, an anode, a gas manifold interconnecting a gas output passageway from each of the cells, and a thermal shell in which the ceramic composite cells are stacked or arranged in electrical series and gas parallel surrounded by shock absorbing and insulating materials, respectively. Also provided are an exhaust fan, thermocouple sensors, a power source, a programmable computer controller with user interface, and a container supporting the computer user interface and having passageways for providing air into the device, and an oxygen output for supplying oxygen from the device. Methods for manufacturing the ceramic composite cells are also provided, including a method for manufacturing bismuth baria oxide and bismuth calcia baria oxide for use in the ceramic materials used within the ceramic composite cell.

Abstract: An electrical power generating device having a plurality of ceramic composite cells, each cell having a cathode and an anode. A thermal shell in which the ceramic composite cells are stacked or arranged in electrical series and gas parallel surrounded by shock absorbing and insulating materials, respectively, is preferably included. Also provided are an exhaust fan, thermocouple sensors, a fuel supply, a programmable computer controller with user interface, and a container supporting the assembly and having passageways for providing air ingress and egress to the device, and power output terminals for the electrical power from the device. Methods for manufacturing the ceramic composite cells are also provided, including a method for manufacturing stabilized zirconia for use in the ceramic materials used within the ceramic composite cell. The cell utilizes a ceramic composite body electrolyte which contains a metal member having a regular pattern of openings.

Abstract: An oxygen welding apparatus capable of generating its oxygen needs without an external oxygen source from a self-contained solid state electrolytic cell which separates oxygen from the air. The cell employs a flexible, ductile ceramic composite as the solid electrolyte. The ductile ceramic composite electrolyte comprises a continuous, ordered, repeating, interconnected ductile metallic array substantially surrounded by and intimately integrated within a ceramic matrix. The cell is connected to a power supply so when current is passed through the cell, oxygen or nitrogen is separated from the air passing through the cell.
