Abstract

A tritium imaging plate technique has been applied to visualize hydrogen distribution and examine hydrogen solubility and diffusivity in a proton-conducting oxide, Y-doped BaCeO₃ (BaCe_0.9Y_0.1O_{3 - α}). Tritium charging of the BaCe_0.9Y_0.1O_{3 - α} specimens was carried out by a gas absorption method using partially tritiated water vapor (HTO, 3 kPa, T/H ~ 10^{- 6}) at temperatures ranging from 673 K to 873 K for a given time. After charging, tritium distributions of the surface and cross section of the halved specimens were visualized using an imaging plate technique. From the tritium concentration and distributions of the surface and cross section, hydrogen solubility and hydrogen (tritium) diffusivity of the BaCe_0.9Y_0.1O_{3 - α} specimens were determined.
