This review article provides an extensive overview of Solid Oxide Fuel Cell (SOFC) technology, focusing on its components, materials, design, operation, and integration strategies. SOFCs are highlighted as a commercially viable power source, particularly in small-scale applications, due to their high efficiency and low environmental impact. The paper discusses the performance and prospects of SOFCs in standalone and hybrid modes, along with their limitations. It also outlines ongoing research and commercialization efforts aimed at enhancing the potential applications of SOFCs as a sustainable and reliable energy system. The introduction emphasizes the growing global demand for energy and the environmental challenges posed by fossil fuel consumption. It highlights the inefficiencies and emissions associated with traditional thermal power plants, contrasting them with the advantages of fuel cells, which convert chemical energy directly into electrical energy with minimal emissions. The article delves into the design and operation of SOFCs, detailing the roles of cathodes, anodes, interconnections, and sealants. It explains the different types of SOFCs, such as planar, tubular, and monolithic designs, and their respective advantages and challenges. The paper also covers the integration of SOFCs with other power generation systems, including gas turbines, steam turbines, and biomass gasifiers, to enhance efficiency and reduce costs. Finally, the limitations of SOFCs, such as polarization losses and the need for hydrogen generation systems, are discussed. The article concludes by emphasizing the ongoing efforts to improve SOFC technology and its potential for contributing to a sustainable energy future.This review article provides an extensive overview of Solid Oxide Fuel Cell (SOFC) technology, focusing on its components, materials, design, operation, and integration strategies.
