We have studied the separation performance of the catalyst using polymer electrolyte membrane water electrolysis (PEMWE). In this study, deuterium was concentrated in the electrolyte in a batch process by circulating the electrolyte. The relationship between the electrolysis volume and deuterium concentration was investigated and evaluated from the mass balance. As a result, approximately 95 at.% deuterium was produced.
