| Abstract Scope |
Ammonia (NH3) has attracted increasing attention as the emerging “ammonia economy” is expected to facilitate the “hydrogen economy”. NH3 can be utilized through catalytic decomposition for hydrogen production, combustion for power generation, and direct electrochemical conversion in fuel cells. However, challenges remain in catalyst design, reactor development, system integration, and operational optimization. Building on more than five decades of research in ammonia catalysis, our team has developed low-temperature ammonia decomposition technologies, ammonia fuel cells, and low-NOx ammonia engines. Among them, direct ammonia solid oxide fuel cells (NH3-SOFCs) are particularly attractive owing to their high efficiency and direct conversion of NH3 into electricity. This report will focus on SOFC ceramic materials and present our recent advances in catalysts and electrode design, elementary reaction modeling, multiphysics simulations, and system development for NH3-SOFCs. These studies aim to advance high-performance NH3-SOFCs and accelerate the integration of renewable energy storage with zero-carbon energy solutions. |
