Abstract:
1. A system for separating oxygen from air so as to enhance oxygen content in an output stream, comprising: a substantially sealed container extending between a first exhaust port and a second exhaust port; an entry port opening into the container between the first exhaust port and the second exhaust port; first, second, and third gas-permeable electrodes disposed across the container, wherein the second gas-permeable electrode is spaced a distance away from the first gas-permeable electrode and the third gas-permeable electrode is spaced a distance away from the second gas-permeable electrode; a first container portion in fluid communication with the entry port, wherein the first and second electrodes define opposite ends of the first container portion: a voltage source configured to supply a voltage to the first and second gas-permeable electrodes so as to create a first static electric field therebetween; and a second container portion in fluid communication with the first container portion and configured to apply a second static electric field to gas therein, wherein the second electrode and the third electrode define opposite ends of the second container portion.
