Abstract
An electrochemical device (10) capable of generating oxygen from air (23) upon application of an electrical current, is made containing a plurality of adjacent cells (12) and (12') electrically connected in series, where each cell contains optional support (22), inner, porous oxygen electrode (20), dense, solid oxide electrolyte (14) on top of the inner oxygen electrode, and outer, porous air electrode (16) on top of the electrolyte, where dense segments of interconnection material (18) are disposed between cells, the interconnection electrically connecting the outer air electrode from one cell to the inner oxygen electrode from an adjacent cell, where the device contains gas impermeable, dense, contacting segments of electrolyte (14) and interconnection material (18) and can contain two end portions at least one of which provides for oxygen delivery.
