对于氢同位素回收，已经提出了在阴极室中真空下使用CaZr 0.9In 0.1O3 −α的电化学氢泵。两种类型的电极-粘贴和化学镀电极-被用来评估的传质过程。当氢泵使用直流电操作时，无论电极类型如何，真空下的电极之间的电压小于大气压下的电压。这一结果表明，在真空下氢泵的性能得到改善。然而，在膏状电极的情况下，电压降低大于镀覆电极的情况。电化学阻抗谱表明，在粘贴电极的扩散系数小于在大气压力下比在真空下。通过对两种电极微观结构的比较，认为膏状电极具有较大的孔隙，更适合于真空氢泵。
For hydrogen isotope recovery, an electrochemical hydrogen pump using CaZr0.9In0.1O3−αunder vacuum in the cathode compartment has been proposed. Two types of electrodes—pasted and electroless plated electrodes—were used to evaluate the mass transfer process. When the hydrogen pump was operated using direct current, the voltage between electrodes under vacuum was less than that under atmospheric pressure, regardless of electrode type. This result indicates that the hydrogen pump performance is improved under vacuum. In the case of the pasted electrode, however, the voltage decrease was larger than that in the case of the plated electrode. Electrochemical impedance spectroscopy revealed that the diffusivity in the pasted electrode was smaller under atmospheric pressure than under vacuum. From comparing the microstructures of the two electrode types, the pasted electrode has larger pores and would be more suitable for the hydrogen pump under vacuum.
