In this study, preparation of a core-shell structured proton-conducting solid electrolytes of 20 vol% BaZr0.8Y0.2O3-δ (20BZY20) for the core and 80 vol% BaCe0.8Y0.2O3-δ (80BCY20) for the shell is done by wet chemistry route.
The obtained samples were characterized for its structure, thermal stability, morphology and elemental distribution of the material.
To address these problems, synthesis of a core-shell structure composed of BZY for the core, to compensate the low chemical stability of BCY, and BCY for the shell, to lower the high grain boundary impedance and promote the sinterability of BZY, is done via wet chemistry modified Pechini method.
In addition, proton conductivity measurements of the synthesized 20BZY20/80BCY20 core-shell structured material is in progress.

Introduction The bond valence sum method is popular method in coordination chemistry to estimate the oxidation states of atoms.
The relation between bond length and bond valence , being a measure of the chemical bond strength and the related valence sum rule, plays a special role in the studies of crystal structure in structural chemistry and atomic microenvironment in coordination chemistry.
