This invention relates to devices for separating oxygen from more complex gasses such as air which contains oxygen, and delivering the separated-oxygen at an elevated pressure for use immediately, or for storage and use later. More particularly, the invention relates to solid state electrochemical devices for separating oxygen from more complex gasses to produce the desired oxygen and delivering the oxygen at elevated pressures up to and exceeding 2000 psig.

A method of manufacturing a thin film electrochemical apparatus is disclosed. A near net shape ceramic element is molded including a planar base region and a plurality of tubular regions. The planar base region is infiltrated with a non-conductive material. Each of the tubular regions is infiltrated with a porous conductive material. A porous catalytic electrode material is applied onto the infiltrated regions to form one of a cathodic and anodic surface. A ceramic electrolyte coating is deposited onto the porous catalytic electrode material. A porous catalytic electrode material is applied onto the deposited ceramic electrolyte coating. A porous conductive material is deposited onto the porous catalytic electrode to form the other of the cathodic and anodic surface.

A porous ceramic substrate structure () having an interior portion () formed with an outer surface () is porous to at least one selected gas (). A first ceramic coating layer () is applied to the outer surface () of the ceramic substrate structure () in a suspension state. The first ceramic coating suspension () has a desired level of viscosity for application to the substrate and is formed with a ceramic electrolyte powder and at least one organic additive. A second ceramic coating layer () is applied to the outer surface () following application of the first coating (). The second coating () is initially applied after the first coating () and in a suspension state. The ceramic layers (and ) substantially prevent gas leakage through the outer surface ().

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 pressure and 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 ().
