The mini-review paper discusses the comparative electrochemical performance of Solid Oxide Fuel Cells (SOFCs) when fueled by hydrogen and ammonia. It explores how these carbon-free energy carriers could contribute to achieving net-zero emissions. The analysis indicates that while hydrogen-fueled SOFCs exhibit stability, ammonia-fueled SOFCs offer higher electrical efficiencies, improved fuel utilization, and advanced power densities. Despite facing challenges like NOx emissions and environmental impacts, ammonia as a fuel source shows promise, particularly at elevated temperatures. The study highlights recent advances in electrode materials, electrolytes, fabrication techniques, and cell structures that could enhance the performance of ammonia-fueled SOFCs. Through a comprehensive literature survey, the review provides insights into future prospects for SOFC research and stresses the importance of further investigating and developing ammonia as a sustainable fuel alternative for SOFCs.
