“…As predicted from the literature [27], there is a clear shift of the n-p transition point with deviation of the A/B cation ratio from unity in ABO 3 perovskite. With increasing concentration of negatively charged cation vacancies, the compensation for this excess negative charge results in a corresponding increase in hole or oxygen vacancy concentration.…”

“…Our results are one or two orders of magnitude lower than the previously reported corresponding values, at all measured temperatures. This discrepancy was attributed to the dependency of the n-p transition point on the electron concentration and on the cation nonstoichiometry [27]. However, because negatively charged cation vacancies and electron/hole concentrations may play different roles in the shift of the n-p transition point, these two effects should be considered separately.…”

In this paper, we report the electrochemical properties of Ni-Ba 0.5 Sr 0.5 Ce 0.6 Zr 0.2 Gd 0.1 Y 0.1 O 3-δ (BSCZGY) anode composites in 3% H 2 O-H 2 for proton conducting solid oxide fuel cells (H-SOFCs). Ni-BSCZGY composites with volume ratio of 30:70, 40:60, and 50:50 were synthesised through mechanical mixing and combustion methods. In combustion method, auto-ignition step led to brown coloured ash, which was calcined at 1000

“…7(a) shows the AC impedance results, along with the equivalent circuit used in fitting. The impedance response of the CaMoO 4 samples according to measured temperature typically showed a single overlapped arc in the Nyquist plot, related to the electrode response [18]. Due to the similar capacitance of the bulk/grain boundary over the studied temperature range, the high frequencies intercept at the overlapped arc could not be further analyzed.…”
