Abstract
An oxygen concentration system for producing oxygen from air comprises an electrochemical oxygen generator mounted within an inner housing. The generator has an outer surface and is adapted to extract oxygen from air by an electrochemical reaction. The oxygen generator fits within a inner housing having the form of an annulus. The inner housing is insulated and is spaced from the outer surface of the oxygen generator to create a first passageway. Air in the first passageway is heated by the generator and rises upwardly out of the passageway by means of convection.
