The effect of trapping protons and vacancies on the hydration defect thermodynamics acceptor-doped ABO<sub>3</sub>oxides was theoretically studied.
The effects of the cell voltage and external conditions on characteristics protonic ceramic fuel are theoretically elucidated.
Barium stannate is known as a promising proton-conducting material for clean energy applications. In this work, we elucidate the effect of interaction protons and oxygen vacancies with acceptor impurities on proton conduction in acceptor-doped BaSnO3. The analysis relies our theoretical developments hydration hopping perovskites. transport theory, based master equation effective medium approximation, provides analytical description considering effects disorder changes potential landscape...
The tracer diffusion coefficient D* and the mobility of protons in proton-conducting oxides АIIВIV 1-xRIII xO3-δ family have been calculated using Monte Carlo method as functions temperature concentration x acceptor impurity RIII. effect protondopant interactions (proton trapping) protonic sites blocking caused by protonproton proton - oxygen vacancy interactions, are analyzed. It is shown that diffusivity depends significantly on dopant content considerably reduced already at small x. value...
Defect formation in yttria with a small content of acceptor impurities equilibrium hydrogen-containing gas phase is studied theoretically. A statistical-thermodynamic description the yttriagas based on approach developed for compounds complex electronic structure [Phys. Stat. Sol. B (1991) Vol. 168, p. 233]. The considered model Y 2 O 3 includes, besides valence and conduction bands, F-center states. energy F-centers was calculated framework variational quantum-mechanical combined molecular...
