Book

Description

Ammonia is a promising carbon-free energy carrier, and solid oxide fuel cells offer an efficient route for its direct utilization. However, ammonia-fueled micro-tubular solid oxide fuel cells face coupled challenges arising from endothermic ammonia decomposition, thermal non-uniformity, and the risk of nickel nitridation in the anode. This book presents a spatially decoupled design based on an internal catalytic layer integrated into the fuel inlet tube. By relocating ammonia decomposition away from the electrochemically active anode, the proposed configuration provides a means of regulating fuel conversion, heat distribution, and anode gas composition. The design is investigated through fixed-bed kinetic experiments, multiphysics modelling, thermodynamic risk assessment, machine-learning surrogate modelling, and multi-objective optimization. The book provides a systematic framework for evaluating the trade-offs among flow resistance, electrochemical performance, thermal uniformity, and anode stability. It is intended for researchers, engineers, and graduate students working in solid oxide fuel cells, ammonia energy systems, catalytic reforming, multiphysics modelling, thermal management, and data-assisted engineering design.
