本发明公开了一种调节液态铅铋合金氧浓度的电化学氧泵，电化学氧泵的工作原理是在外部施加的直流电动势下，作为阴极的界面上解离产生氧离子，氧离子在电场作用下通过固体氧化物电解质迁移，在阳极界面上转化成氧分子。因此，外部直流电源通过电极丝施加两个不同方向的电动势，驱使氧离子通过固体氧化物电解质向液态铅铋合金中迁移，或驱使液态铅铋合金中的氧离子通过固体氧化物电解质向参比电极迁移，析出氧分子，使液态铅铋合金中氧含量增大或减小，从而达到调节液态铅铋合金氧浓度的目的。

The invention discloses an electrochemical oxygen pump for regulating the oxygen concentration of liquid lead-bismuth alloy. The working principle of the electrochemical oxygen pump is to dissociate and produce oxygen ions at the interface of the cathode under the external applied DC electromotive force, and the oxygen ions migrate through the solid oxide electrolyte under the action of the electric field, and convert into oxygen molecules at the anode interface. Therefore, the external DC power supply applies two different directions of electromotive force through the electrode wire to drive the oxygen ions to migrate to the liquid lead-bismuth alloy through the solid oxide electrolyte, or to drive the oxygen ions in the liquid lead-bismuth alloy to migrate to the reference electrode through the solid oxide electrolyte, and precipitate oxygen molecules, so as to increase or decrease the oxygen content in the liquid lead-bismuth alloy, thus achieving the purpose of adjusting the oxygen concentration of the liquid lead-bismuth alloy.
