Summary: In this study, In-doped swedenborgite oxide materials were prepared and thoroughly investigated for their phase structure, electrical conductivity, thermal expansion coefficient, thermal stability, and electrochemical properties. The partial substitution of In for Y and Ca had minimal effect on the properties of the materials. The samples showed excellent tolerance to CO2 at high temperatures and the YCI0.2BCZ composition exhibited low resistance and high power density, making it a promising cathode material for IT-SOFCs.

Summary: This study evaluates the properties of BaO-Al2O3-SiO2 (SAB) glasses incorporated with CaO and V2O5 as modifiers and additives. The addition of CaO decreases the electrical resistivities of the glasses, while increasing the V2O5 content increases the resistivities due to lower ionic mobility. The presence of V2O5 improves the wettability and fracture strength of the glasses on the substrate. The SAB glass with 20 wt% CaO and 2 wt% V2O5 exhibits excellent sealing properties and compatibility with high-temperature substrates, making it suitable for solid oxide fuel cell applications.

Summary: The polycrystalline samples of BaNi2(V1-xPxO4)2 (x = 0-1) were synthesized via a solution combustion synthesis. The substitution of vanadium (5+) cations by smaller phosphorus (5+) cations leads to compression of the [Ni2(V1-xPxO4)2]infinity layers in the ab plane and elongation of the BaO12 polyhedra along the c axis. The melting point of the samples increases with increasing phosphorus concentration. The electrical conductivity of BaNi2(V1-xPxO4)2 is measured and electron transfer is explained by the formation of Ni3+ along the Ni-O-Ni chains.

Summary: In this study, a three-dimensional electro-thermomechanical coupled model is established to investigate the influence of interconnector (IC) structure on the electrical performance and mechanical stability of solid oxide fuel cells (SOFCs). The results show that IC design with discrete ribs can enhance the maximum power density without significantly affecting the stress on the electrodes. The stress distribution is primarily determined by the geometrical structure of the IC. Discrete cylindrical ribs and discrete cubic ribs with rounded corners are better choices for balancing electrical power output and mechanical stability.

Summary: A low leakage rate sealant of 10 wt% ZrO2-added CaO-K2O-Na2O-BaO silicate glass for SOFC was studied. The sealant's structure remained stable at high temperatures with leakage rates below 10(-4) sccm.cm(-1), and no crystals, except for ZrO2, were found in XRD analysis after heating at 800 degrees C for 100 hours. ZrO2 was distributed in the glass matrix and played a role in preventing over-softening at operating temperature. SEM analysis at 750 degrees C for 100 hours confirmed good compatibility between the sealant and SUS430 interconnect in both oxidizing and reducing atmospheres.

Summary: This study demonstrates an approach to achieving full thermo-mechanical compatibility between the cathode and other cell components for solid oxide fuel cells. By introducing a thermal-expansion offset and using reactive sintering to form a composite electrode, the research shows high activity and excellent stability of the electrode. The introduction of reactive negative-thermal-expansion components may provide a general strategy for developing fully compatible and highly active electrodes for SOFCs.

Summary: The effect of interconnect deformation on the temperature and thermal stress of a solid oxide fuel cell (SOFC) stack was simulated based on the thermal-chemical-electrical-mechanical multiphysics coupling theory. The results show that the interconnect mainly experiences a compressive strain when the operating voltage is above 0.85 V, and a tensile strain with increasing voltage below 0.85 V. Interconnect deformation significantly increases the thermal stress of the cells within the stack, but improves the uniform distribution of thermal stress. The coupling effect of interconnect deformation on cell thermal stress within the stack varies at different operating voltages.

Summary: The thermomechanical reliability and lifetime of solid-oxide fuel cells are significantly affected by thermal mismatch between anode and electrolyte layers. This study presents a numerical analysis of topology optimization of the microstructure of Ni-8YSZ anode to minimize the thermal mismatch. The optimized microstructures show high three-phase boundary density and increased Ni-pore interfacial areas, providing potential for enhancing ion conductivities and aiding in the design of future electrodes.
