Abstract:
Solid oxide fuel cells (SOFCs) offer high efficiency and fuel adaptability but face challenges like high operating temperatures and material
degradation. This study focuses on innovative solutions, including doped ceria-based electrolytes with ionic conductivity of 0.1 S/cm at 600◦C,
reducing operating temperature by 200◦C and extending lifespan by 29.15%. Composite anodes with hierarchical pores achieved a power density
of 1.2 W/cm2 (25% improvement) and maintained stability over 5000 h with <1% degradation per 1000 h. Hybrid integration with micro gas
turbines improved efficiency to 69.48% (14.28% increase) and cut CO2 emissions by 21%, advancing SOFC viability as sustainable energy
solution.
