摘要

利用固相反应法合成CaZr0.9In0.1O3-α质子导体并将其作为电解质组装成浓差电池短路氢泵

在电池短路情况下

通过改善物理条件（真空抽取、O2或Ar气体携带）下实现对铝液的无污染脱氢过程。结果表明

该氢泵显著降低铝液中的氢含量

100g铝液中的氢含量由79.84mL降至0.15mL。此外

试验还探索了氢泵在外加电压1.5V条件下的脱氢效果

发现可将100g铝液中的氢含量由6.43mL降至3.67mL

也达到了一定的脱氢效果。

Abstract

Hydrogen pump apparatus was made up of CaZr0.9In0.1O3-αproton conductor as solid electrolyte

Ni-Cr wire as electrode wire.The molten aluminum was dehydrogenated by short-circuiting the pump.Furthermore

both the gas carrying and extracting hydrogen methods were used to increase the dehydrogenation rate.Meanwhile

the hydrogen sensor was employed to measure the hydrogen content in the molten aluminum quantitatively to monitor the dehydrogenation effect.The results reveal that under the extracting hydrogen condition

the hydrogen content can be reduced from 79.84mL/100g·Al to 0.15mL/100g·Al.It proves that short-circuit method to dehydrogenate aluminum is practicable.In addition

the dehydrogenation effect was analyzed with the pump applied 1.5Vvoltage.The results reveal that the hydrogen content is dropped from 6.43mL/100g·Al to 3.67mL/100g·Al.
