Title:
OXYGEN PUMP, METHOD FOR MANUFACTURING OXYGEN PUMP, AND STORING WAREHOUSE COMPRISING OXYGEN PUMP
Document Type and Number:
WIPO Patent Application WO/2010/041396
Kind Code:
A1
Abstract:
Disclosed is an oxygen pump comprising an external direct current power supply that takes in current from outside, a porous negative electrode (3) having gas exchangeability, a porous positive electrode (2) having gas exchangeability, a porous separator (1) that is held between the negative electrode (3) and the positive electrode (2) and has been impregnated with a metal ion-containing electrolysis solution, a negative electrode-side current collecting electrode (5) that is connected to the external direct current power supply and is provided outside the negative electrode (3), and a positive electrode-side current collecting electrode (4) that is connected to the external direct current power supply and is provided outside the positive electrode (2). An electric power is fed by the external direct current power supply to the negative electrode-side current collecting electrode (5) and the positive electrode-side current collecting electrode (4) to allow oxygen to migrate from a negative electrode-side gas phase (10) into a positive electrode-side gas phase (9). An aqueous solvent which is actuated at ordinary temperatures and pressures is used, and a very small amount of an electrolyte is impregnated and held. Accordingly, the oxygen pump is advantageously free from, for example, leakage of the electrolyte and can have a large area to increase an oxygen carrying capability.
