Materials for Solid Oxide Fuel Cells

Solid oxide fuel cells (SOFCs) proposed a bright pathway towards efficient and sustainable energy conversion, yet certain challenges remained in achieving long– term stability and optimal performance. This chapter provided a comprehensive overview of recent advancements in materials tailored to enhance the stability and performance of SOFCs. The chapter also commenced with an analysis of the fundamental aspects of SOFC materials, encompassing electrolyte, electrode, and interconnect materials. It proceeded to elucidate degradation mechanisms, such as sintering, poisoning, and thermal/chemical instabilities, which impeded operational longevity. Strategies to mitigate these challenges were explored, encompassing the creation of different electrolyte resources by enhanced ionic conductivity and stability of chemical, advanced electrode architectures, and resilient interconnect materials. Nano structuring, surface modification, and innovative fabrication techniques were discussed for tailoring material properties to optimize performance and durability. The integration of advanced characterization methods for predictive insights into material behavior was also highlighted. Ultimately, this chapter underscored the significance of recent research in advancing SOFC materials toward commercial viability, thereby facilitating their broader adoption as a clean and efficient energy technology.
