Fundamental and technological aspects of thermochemical expansion of proton-conducting oxides: a case study of BaSn_1−<i>x</i>Sc_<i>x</i>O_{3−<i>δ</i>}

Abstract

This work provides insight into the thermal and chemical expansion behaviors of proton-conducting oxides, using Sc-doped BaSnO 3 materials as examples. Both fundamental and applied aspects related to thermo-chemical expansion are thoroughly discussed.
