煤基/碳基固体氧化物燃料电池技术发展前沿

作为新一代能源技术，固体氧化物燃料电池（solid oxide fuel cell, SOFC）发电系统具有能量转化效率高、燃料适应性广、价格低廉、安全方便等特点。SOFC技术通过长期研究和发展，其电解质、阴极、阳极等关键材料核心技术已经突破，并初步具备产业化发展的基础，但其整体性能的优化仍有待深入研究，其中解决碳基燃料SOFC长期稳定性是实现SOFC商业化的关键所在。必须进一步探索SOFC发电技术中碳基燃料电化学和催化化学过程，解决材料稳定性、界面相容性和耐热循环性，系统中传热、传质与电极反应耦合等科学问题；发展纳米微米级薄膜制备技术、SOFC电池堆装配和系统集成技术，实现SOFC整机性能的稳定和优化，推动SOFC跨越式发展。

Development of Coal/Carbon Based Solid Oxide Fuel Cell

As a new energy technology, solid oxide fuel cells (SOFCs) are the most efficient energy conversion devices, which hold some advantages, such as fuel versatility, low cost, safety, conveniency and so on. After a long term research and development, now, the core technology including fabrication and industrialization of SOFC key materials, such as electrolyte, cathode, and anode, have been achieved, whereas it still needs to be focused on the performance optimization. It is the most important issue of SOFC commercialization to achieve long term stable operation of carbon based SOFC. On the other hand, it is necessary to do basic research, such as carbon based electrochemical and catalytic chemical process, materials stability, interface compatibility, thermal cycle, heat transfer, mass transfer, and electrode reaction. It is also necessary to develop nano micro film fabrication, SOFC stack assemble, system integration, SOFC performance optimization and so on. All of above will put forward the rapid development of SOFC.
