Extraction of hydrogen into vacuum by electrochemical hydrogen pump using a high temperature type proton conductor

为了回收氢同位素，提出了一种负极室真空下的电化学氢泵。两种电极--粘贴电极和化学镀电极--被用来评价传质过程。当氢泵采用直流运行时，真空下的氢泵性能得到了改善。电化学阻抗谱表明，常压下粘贴电极的扩散系数小于真空下的扩散系数。

For hydrogen isotope recovery, an electrochemical hydrogen pump under 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 hydrogen pump performance is improved under vacuum. Electrochemical impedance spectroscopy revealed that the diffusivity in the pasted electrode was smaller under atmospheric pressure than under vacuum.
