Abstract

An electronic controller (16) controls the operation of an electrochemical oxygen generating system (14) producing a desired gas. The product gas is fed to a storage unit (12) or a regulator (28) and pulsing valve (28) controlling the gas flow to a user. A two-stage system (180) combines a low pressure 100 and a high pressure (150) gas generating subsystems. The low pressure subsystem (100) uses IMAT's (106) to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem (150) uses IMAT's (160) to pump oxygen to high-pressure oxygen storage devices (194).
