The blanket tritium recovery system using the hydrogen pump with solid electrolyte membrane has been proposed by the present authors. Perovskite-type ceramic such as SrCe_0.95Yb_0.05O_3-a, is one of the candidate protonic conductor for hydrogen pump and its ionic hydrogen transportation properties are being investigated. Deuterium transportation properties were investigated and were compared with H₂ to understand the isotope effect. The basic hydrogen isotope transportation property of SrCe_0.95Yb_0.05O_3-a, its technical feasibility, and issues for further development toward practical devices were revealed.
