|発明の名称||OXYGEN GENERATING DEVICE AND OXYGEN GENERATING METHOD IN MOLTEN SALT|
PROBLEM TO BE SOLVED: To provide an oxygen generating method and an oxygen generating device where, in an electrolytic reduction process for oxide in a molten salt, carbon dioxide is not generated, and also, electrodes are not consumed during electrolysis.
SOLUTION: The electrolytic reduction device 20 is equipped with: a cathode 1; an anode 2; a molten salt 3; a reaction vessel 4 for storing the molten salt 3; and a d.c. power source 5 for flowing electric current through the cathode 1 and the anode 2, and in which oxide ions comprised in the molten metal 3 are oxidized in the reaction vessel 4, so as to generate oxygen. It is characterized in that the anode 2 is a diamond electrode. Further, the oxygen generating method contains a process where, to the molten salt 3 inserted with the cathode 1 and the anode 2 and comprising oxide ions, electric current is made to flow through the cathode 1 and the anode 2, and it is characterized in that a diamond electrode is used as the anode 2. The oxide ions are electrolytically oxidized on the diamond electrode, so as to generate oxygen.
