Solid oxide fuel cells represent a promising option for sustainable energy production as global energy demand is projected to increase by 50 percent by 2050. These devices achieve electrical efficiencies of up to 60 percent while maintaining a minimal environmental footprint. Compared to alternative fuel cell systems, they offer superior energy efficiency and more favourable ecological outcomes. The technology is versatile, with potential utility across transportation, power generation, grid storage, portable electronics, and residential heating and power. Realising widespread deployment requires improvements in cell component materials and manufacturing, particularly concerning durability and resistance to impurities. Key barriers to adoption include high capital costs, component longevity, long-term operational reliability, and the engineering complexities of integrating cells into existing energy networks, alongside a requirement for supportive policies and regulatory frameworks.
Global energy demand is projected to rise dramatically over the coming decades, driving the need for cleaner, highly efficient power sources. Solid oxide fuel cells can generate clean electricity across sectors from homes to transport. Overcoming remaining hurdles around durability and manufacturing costs will be critical to deploying them as dependable components of a sustainable low-carbon energy system.
Potential applications encompass stationary power generation, energy storage, transportation, portable electronics, and residential systems. Likely users include power utilities, automotive manufacturers, and consumer electronics developers. However, the technology faces barriers in manufacturing cost, long-term reliability, component longevity, and system integration. Given these challenges, the work points to an applied technology that requires further manufacturing optimisation, cost reduction, and regulatory support before achieving large-scale market adoption.

In light of the anticipated 50% increase in global energy demand by 2050, the demand for innovative, environmentally conscious, efficient, and dependable energy technologies is paramount. Solid oxide fuel cells (SOFCs) offer a promising solution for sustainable energy production. This comprehensive review provides a detailed analysis of SOFCs, covering their fundamentals, materials, performance, and diverse applications, while also addressing technological challenges and future prospects. The review emphasizes the key advantages of SOFCs, including their high efficiency of up to 60% and minimal environmental impact. It explores the significance of impurity resistance and durability in materials and manufacturing processes for SOFC components. Comparative evaluations demonstrate the superior energy efficiency and ecological effects of SOFCs compared to other fuel cell technologies. SOFCs’ versatility and potential are showcased through their applications in transportation, power generation and storage, portable devices, and residential usage. However, challenges such as cost, longevity, reliability, and integration with other energy systems are identified, emphasizing the need for supportive policies and regulations.
