An electronic controller () controls the operation of an electrochemical oxygen generating system () producing a desired gas. The product gas is fed to a storage unit () or a regulator () and pulsing valve () controlling the gas flow to a user. A two-stage system () combines a low pressureand a high pressure () gas generating subsystems. The low pressure subsystem () uses IMAT's () to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem () uses IMAT's () to pump oxygen to high-pressure oxygen storage devices ().

Oxygen generator with storage and conservation modes

An oxygen concentrator system includes at least one oxygen concentrator sub-system and a plenum subsystem. The at least one oxygen concentrator sub-system produces oxygen-enriched air which is outputted to both the oxygen concentrator system output and to a plenum chamber within the plenum subsystem. The plenum chamber is trickle charged with the oxygen-enriched air when the at least one oxygen concentrator sub-system produces an excess amount of oxygen-enriched air. Should the demand for oxygen-enriched air exceed the capability of the at least one oxygen concentrator sub-system, additional oxygen-enriched air is provided by the plenum chamber until such time that the capability of the at least one oxygen concentrator sub-system exceeds the demand of oxygen-enriched air. At that time, oxygen-enriched air is no longer provided by the plenum chamber but rather the plenum chamber is again trickle charged.
