ABSTRACT:
An oxygen generator having a honeycomb body made of oxygen ion conducting material separates oxygen from a first gas, such as air. The honeycomb body has a plurality of generally parallel first and second channels coated with a layer of porous metal conductor which serve as electrodes. The first and second channels are arranged in alternating rows across the face of the honeycomb and the respective electrodes therein are oppositely charged by connection to a voltage source. Oxygen ions from a first gas in the first channels are caused to tranit across the channel walls to the second channels under an applied voltage. Oxygen generated in the second channels may be collected in a manifold through a set of third channels which intersect the sealed second channels, and used in applications such as home breathing apparatus'. Additional features are included in the honeycomb body and in the design of manifolds to facilitate the supply of a first gas and collection of oxygen. Preferably operating at elevated temperatures, the oxygen generator may also incorporate a heater and valve for start up and a heat exchanger for thermally efficient steady state operation.
