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。
The solid state reaction method was used to synthesize CaZr0.9In0.1O3-α proton conductor and assemble it into a concentrated-battery short-circuited hydrogen pump. When the battery was short-circuited, the CaZr0.9In0.1O3-α proton conductor was modified by physical conditions (vacuum extraction, O2 or Ar gas) Realize the pollution-free dehydrogenation process of molten aluminum. The results show that the hydrogen pump significantly reduces the hydrogen content in the aluminum liquid and the hydrogen content in the 100 g aluminum liquid drops from 79.84 mL to 0.15 mL. In addition, the experiment also explored the dehydrogenation effect of the hydrogen pump under the applied voltage of 1.5V and found that the hydrogen content in 100g aluminum liquid can be reduced from 6.43mL to 3.67mL, and a certain dehydrogenation effect has also been achieved.
