Summary: The development of solid oxide cell (SOC) based on proton-conducting electrolyte is hindered by performance degradation caused by mismatch in thermal expansion coefficients between the electrolyte and the oxygen electrode. This paper proposes a solution by increasing the TEC of the electrolyte and demonstrates the improved stability of SOC with Fe-doped electrolyte and oxygen electrode materials. The Fe doping increases the TEC of BaZr0.3Ce0.5Y0.1Yb0.1O3-delta electrolyte and decreases the TEC of PrNi0.5Co0.5O3-delta oxygen electrode material.

Summary: Innovations in materials science are crucial for addressing technological challenges, requiring the design of materials with tailored properties. This study developed ceramic materials in the BaZr0.8Y0.2-xMnxO3-delta series, finding that thermal expansion and hydration decrease, and total electrical conductivity reduces with increasing Mn content. XPS analysis and NEXAFS indicated varying oxidation states of Mn atoms depending on ambient conditions, suggesting a hydration mechanism mediated by Mn oxidation and proton attachment to oxygen neighbors.

Summary: The bonding nature of hydroxide ions in two proton-conducting oxy-hydroxides, BZT and BZW, was studied using FT-IR spectroscopy at temperatures of 40-600°C. A broad absorption peak at 2500-4000 cm-1, attributed to O-H stretching vibration, was deconvoluted into four components representing proton sites in the crystal lattice. The different temperature variations of peak intensities indicated a difference in proton site preference between BZT and BZW, suggesting the importance of B-site cationic order in proton distribution and conduction properties.

Summary: Yttrium-doped barium zirconate, a solid electrolyte with advantageous properties for fuel cells, was characterized using photoluminescence and photoluminescence excitation spectra to understand the atomic arrangement near the oxygen vacancy. The study found that the photoluminescence spectra consisted of recombination at the grain boundary region, recombination at a vacancy defect with an unpaired electron, and the transition of the electronic state of the oxygen vacancy. By analyzing the peak position and corresponding excitation spectrum, information on the atomic arrangement adjacent to the oxygen vacancies, which is crucial for designing materials with high protonic conductivity, was obtained.

Summary: This study investigates the effect of polarization resistances on current leakage and the distribution of relaxation times (DRT) analysis of electrochemical impedance spectra (EIS) for solid oxide cells (SOCs) with GDC electrolyte and protonic ceramic cells (PCCs) with BZYb electrolyte. The results show that the polarization resistances increase with increasing current density in SOC with GDC electrolyte, but exhibit the opposite tendency in PCC with BZYb electrolyte. This suggests that the effect of current leakage on polarization resistance is related to the conductivity of the electrolyte.

Summary: We demonstrate that protons strongly inhibit certain phonons in hydrated barium zirconate. By conducting terahertz spectroscopy and infrared reflection spectroscopy measurements on anhydrous and hydrous acceptor-doped barium zirconate sintered pellets, we provide evidence for this effect. Last and Slater phonon modes are significantly suppressed with proton doping, while phonons are not damped with trivalent dopants. This phenomenon is attributed to the picosecond motion of protons, such as hydroxyl rotation and attempt motion of proton hopping, coupled with the phonon.
