Abstract
A planar oxygen pumping device (10) has a first and second oxygen ion conductive solid electrolyte material layer (12, 18). A first electrode (16) is between, and in contact with, the first electrolyte material layers and the second electrolyte material layer. A second electrode (14) is on the first electrolyte material layer. A third electrode (20) is on the second electrolyte material layer. At least one of the first and second electrolyte layers has a porosity sufficient to establish at the first electrode (16) an oxygen concentration dependent upon the ambient atmosphere.
