Combustion synthesis and characterization of nanocrystalline proton conducting Sr(Ce0.6Zr0.4)0.95Yb0.05O3−δ

Stability and electrical property of Ba1−xSrxCe0.8Y0.2O3−δ high temperature proton conductor

“…Methods such as substituting isovalent and aliovalent ions into either A site or B site for the ABO 3 structure [9][10][11][12][13][14] may result in modified point defect concentrations which have impact on the electrical conductivity. In addition, materials synthesis using different preparation methods can affect the local stoichiometry and grain boundary interfaces resulting in conductivity modifications [15,16].…”

Material characterization and electrochemical performance of Sr(Ce_0.6Zr_0.4)_0.8Y_0.2O_{3−δ} proton conducting ceramics prepared by EDTA-citrate complexing and solid-state reaction methods

“…In contrast, SrCeO 3 -base oxide has high proton conductivity at high temperature; 10), 11) therefore, the hydrogen flux of SrCeO 3 -base oxide is higher than that of BaCeO 3 -base oxide. 12), 13) In addition, the structure stability of SrCeO 3 -base oxide is better than that BaCeO 3 -base oxide in humid or CO 2 -contained atmospheres. 14) From the literatures, 4),8),14)18) it was found that yttrium doping can enhance the conductivity of SrCeO 3 -base oxide proton conductor, but the structure stability is still not good enough to prevent structure decomposition in humid atmosphere.…”
