Research Abstract

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.
