Abstract: An apparatus for generating high purity oxygen is described which comprises a linear actuator, a dual acting air cylinder, two molecular sieve beds, and valving. The linear actuator drives the air cylinder back and forth, compressing air on both the forward and return stroke. On each stroke, fresh air is compressed into one of the beds, generating oxygen. Simultaneously, the opposite bed exhausts to ambient pressure and the non-compressing side of the cylinder draws in fresh air. The cylinder then reverses, which compresses air into the opposing bed and allows the first bed to exhaust.

Abstract: A oxygen generation system comprising a plurality of cells arranged in a stack. Each cell is comprised of a BICUVOX electrolyte and a pair of Inconel® electrodes placed in electrical contact with the BICUVOX electrolyte to produce a flow of oxygen therethrough. The BICUVOX electrolyte is comprised of a square thin plate. The electrodes are plates having the same dimensions as the electrolyte. The electrode plates are machined with gas flow channels oriented to separate high purity oxygen gas flow from oxygen-depleted gas flow. The stack is enclosed in a tubular manifold composed of magnesium oxide and has a diameter slightly larger than the diagonal length of the electrolyte and electrode plates. The stack is sealed at its four corners to the inside surface of the manifold creating four separate passages for flow of oxygen-containing gas, high purity oxygen gas, and oxygen-depleted gas.
