DEVICE FOR ELECTROCHEMICALLY TRANSPORTING OXYGEN

摘要

PURPOSE:To selectively transport concd. pure oxygen to oxygen utilizing equipment from an oxygen-contg. gas source by using an electrochemical cell divided into a cathode chamber and an anode chamber by the cation-exchange membrane. CONSTITUTION:The electrochemical cell main body 4 is divided into an anode chamber 8 provided with an anode collector 10 and a cathode chamber 5 furnished with a cathode collector 7 by a cation-exchange membrane 1 with an anode 9 bonded to one side and a cathode 6 to the other side. The main body 4, oxygen-contg. gas source 1 (closed structure) and oxygen utilizing equipment are connected to the second dehumidifier 18, gas-liq. separator 14, first dehumidifier 15 and water tank 17. Consequently, oxygen alone is selectively transported from the source 1, and oxygen having 99.9% purity is transported to the oxygen utilizing equipment.
