Summary: Three different mixtures were developed as sealants for solid oxide fuel cell (SOFC), using natural volcanic rock basalt, waste window glass, and Na2CO3. The mixtures were melted and cast into molds, and the glass parts were analyzed to determine the coefficient of thermal expansion. Glass was then coated onto stainless steel substrates and subjected to heat treatment to ensure bonding and sealing. The interface between the glass-ceramic sealing and steel substrate, as well as the crystallization mechanisms, were examined to determine suitability for SOFC.

Summary: A series of Ce-doped coatings (Mn1.5-xCo1.5-xCe2xO4+delta, x = 0, 0.025, 0.05, and 0.1) were prepared to improve the electrical conductivity of solid oxide fuel cell (SOFC) interconnect coatings. Experimental results showed that Ce doping effectively reduced the area-specific resistance of the coatings. However, excessive Ce doping led to more structural defects and weakened the oxidation resistance of the coatings.

Summary: This review summarizes various types of solid oxide fuel cells (SOFC) and describes their structural features, advantages, and disadvantages. Among the well-studied dual-chamber SOFC, those with anode-supported design and oxygen-ion conducting electrolyte are found to be the most suitable for operation at temperatures below 800 degrees C. Other promising types for low-temperature operation include SOFC with proton-conducting electrolyte and electrolyte-free fuel cells, although further research and development are needed for commercialization.

Summary: This study investigates coatings to mitigate the dual-atmosphere corrosion effect in Solid Oxide Fuel Cells (SOFC). The results show that coatings on the air-side can improve the sample's lifetime by reducing Cr evaporation even in a dual-atmosphere. Fuel-side coatings suppress the dual-atmosphere effect and the best results are obtained with metallic Al and Al2O3 coatings.

The increase in Cu concentration in the coatings led to a transformation in the crystalline structure and improved electrical conductivity. However, the Cr-corrosion phenomenon at elevated temperatures weakened the oxidation resistance of the coatings. The Cu1.0Mn2.0O4 coating exhibited good electrical conductivity and resistance against Cr-corrosion, making it a promising candidate for SOFC applications.

Summary: The manganese ferrite was synthesized by milling reactive siderite and MnO2 powder mixtures, with and without subsequent heat treatment. The impact of milling conditions and calcination temperature on conversion of precursors was assessed, based on XRD peaks intensities and thermogravimetry. The best conditions for complete conversion were obtained by milling at 650 rpm for 6 h and calcination at 650 degrees C. The processing conditions affected the structural features of the spinel phase, and the conversion of FeCO3 occurred more readily than MnO2.

Summary: Ruddlesden-Popper La2-xBaxNiO4 +/-delta (x = 0-1.1) nickelates were synthesized and evaluated for electrocatalytic applications. The study included characterization of structural, microstructural, and dilatometric properties, determination of oxygen nonstoichiometry, measurement of electrical conductivity and oxygen permeability, and assessment of chemical compatibility. The formation of phase-pure solid solutions was limited to x = 0.5. The substitution of lanthanum by barium in La2-xBaxNiO4+delta resulted in a decrease in oxygen excess and the generation of electron-holes, leading to an increase in p-type electronic conductivity. The ceramics showed moderate thermal expansion coefficients and good chemical compatibility with BaZr0.85Y0.15O3-delta solid electrolyte.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
