14 A Theoretical Study on Proton Conduction Mechanism in BaZrO 3 Perovskite

Fig. 14.18 The potential
energy curves for proton
conduction in Ba 2 Zr 3 O 4 H
model: proton conduction
paths along (a) Zr–O–Zr,
(b) O–O diagonal line and
(c) toward centre
proton conductive SrTiO 3 and BaZrO 3 are used in electrolyte of solid oxide fuel
cell (SOFC). In a practical use, safety problem cannot be negligible. The relationship between H 2 defect and safety should be explored.
