Fuel cells are efficient energy conversion devices that convert the chemical energy of a fuel into electricity via electrochemical reactions. Proton Exchange Membrane Fuel Cells (PEMFCs), Alkaline Fuel Cells (AFCs), and Direct Methanol Fuel Cells (DMFCs) are typically operated at room temperature and thus are featured by fast startup and are suitable for portable and mobile applications. In contrast, Solid Oxide Fuel Cells (SOFCs) are typically operated at a high temperatures ranging from 400 °C to 1000 °C. The high-temperature operation enables the direct use of alternative fuels in SOFCs as internal reforming of hydrocarbons can be achieved in the porous anode of SOFC. In addition, the waste heat from a SOFC stack is of high quality and can be recovered by integrating the stack with other thermodynamic cycles for co- or tri-generation to achieve enhanced system efficiency. Hence, SOFCs are particularly suitable for large-scale stationary applications.
This book aims to provide an overview of the SOFC technology with a focus on the recent developments in new technologies and new ideas for addressing the key issues associated with SOFC developments. The contributing authors consist of both young, promising experts and renowned senior scientists in the field. Key issues related to SOFC performance improvements, long-term stability, mathematical modelling, as well as system integration/control are addressed, including material developments, novel infiltration technique for nano-structured electrode fabrication, advanced focused ion beam- scanning electron microscopy (FIB-SEM) technique for microstructure reconstruction, Lattice Boltzmann Method (LBM) simulation for understanding the fundamental transport and reaction phenomena at pore-scale, multi-scale modeling and simulation, SOFC integration with buildings and other cycles for stationary applications.
The editors express their appreciation to the contributing authors for their contributions to this book. Last, but not least, the editors acknowledge the efforts of the professional staff at RSC for providing invaluable editorial assistance.
