Abstract:
A ceramic oxygen generator is described which is capable of modular construction to permit the oxygen generation capacity to be expanded. An ionically conducted ceramic electrolyte is formed into a series of rows and columns of tubes (12) on a tube support member (14) and like electrolyte bodies can be connected together to form a manifold (24) therebetween for oxygen produced in the interiors of the tubes (12). An electrical connection between tubes (12) is formed such that the anodes and cathodes of tubes in a column are connected in parallel while the tubes (12) in the row are, respectively, connected anode to cathode to form a series connection.
