Hexagonal perovskite-related oxides BaTaMoO (BTM) have recently been reported as promising electrolyte materials for intermediate-temperature solid oxide fuel cells (IT-SOFCs). In this work, sintering properties, thermal expansion coefficient, and chemical stability of BTM were studied. In particular, the chemical compatibilities of (LaSr)MnO (LSM), LaSrCoO (LSC), LaSrCoFeO (LSCF), PrBaMnO (PBM), SrFeMoO (SFM), BaCoFeZrYO (BCFZY), and NiO electrode materials with the BTM electrolyte were evaluated. The results show that BTM is highly reactive with these electrodes, in particular, BTM tends to react with Ni, Co, Fe, Mn, Pr, Sr, and La elements in the electrodes to form resistive phases, thus deteriorating the electrochemical properties, which has not been reported before.
最近有报道称，六方钙钛矿相关氧化物BaTaMoO（BTM）是用于中温固体氧化物燃料电池（IT-SOFCs）的有前景的电解质材料。在这项工作中，研究了BTM的烧结性能、热膨胀系数和化学稳定性。特别地，评估了（LaSr）MnO（LSM）、LaSrCoO（LSC）、LaSrCoFeO（LSCF）、PrBaMnO（PBM）、SrFeMoO（SFM）、BaCoFeZrYO（BCFZY）和NiO电极材料与BTM电解质的化学相容性。结果表明，BTM与这些电极具有高反应活性，特别是BTM倾向于与电极中的Ni、Co、Fe、Mn、Pr、Sr和La元素反应形成电阻相，从而使电化学性能恶化，这在以前尚未见报道。
