Summary: The study found that in a solid oxide fuel cell-gas turbine hybrid system, higher fuel utilization factors and pressure ratios increase the air flow requirement to maintain acceptable temperature differences and thermal gradients. The highest efficiency is achieved at higher operating voltage, moderate pressure ratio, and moderate fuel utilization, while the lowest cost of electricity is obtained at lower operating voltage, the same pressure ratio, and lower fuel utilization.

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: Scandia-stabilized zirconia (ScSZ) has higher conductivity compared to yttria stabilized zirconia (YSZ), but undergoes phase structure transition, affecting stability in SOFC applications. 10Sc1CeSZ, a commonly doped ScSZ, experiences Ce4+ - Ce3+ transition, resulting in lower fracture strength. Co-dopants such as Nd, Sm, and Gd show promise in enhancing the stability of ScSZ in reduced SOFC environments.

Summary: In this study, a facile and scalable urea assisted ultrasonic spray infiltration technique was proposed for the nanofabrication of durable nanostructured solid oxide fuel cell (SOFC) cathodes. The technique eliminates the need for high temperature calcination cycles and allows for faster fabrication of the cathodes. The results showed that the urea assisted infiltration combined with ultrasonic spray technique can be scaled up for any desired cathode area and lead to highly durable SOFC performance.

Summary: Pyrochlore structure materials have unique crystal structure, electrical properties, and thermal stability, making them widely applicable in catalysis, nuclear waste encapsulation, sensors, and electronic devices. The ionic/electronic conductivity of these materials is crucial for their performance in solid oxide fuel cells, where factors like cation radius ratio, oxygen migration, vacancy formation, and dopant addition play significant roles in enhancing the conductivity. Research has shown that controlling these factors can improve the ion and electron transport properties of pyrochlore materials, ultimately leading to better performance in various applications.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.

Summary: A single-step wet-chemical synthesis method for NiO-SDC colloidal ink has been developed for inkjet printing of nanostructured anodic layers with enhanced catalytic activity in solid oxide fuel cells (SOFCs). The ink solution contains stable nanoparticles with a main size of 11.85 nm, which leads to a significant reduction in the area-specific resistance of the inkjet-printed half-cell. The microstructure engineering using inkjet printing results in a cermet layer with enhanced catalytic activity for SOFCs.
