摘要 固体氧化物燃料电池(SOFC)是一种将储存在燃料和氧化剂中的化学能通过电化学反应的方式直接转换为电能和中高温热能的全固态发电装置,被认为是最接近商业化的先进清洁高效发电技术之一。为了考察SOFC在变负荷条件下的稳态和非稳态特性,在MATLAB模拟环境下,建立了板式SOFC的一维稳态和非稳态分布参数模型,该模型充分考虑了SOFC中传热传质、流体流动、化学与电化学反应等因素相互耦合的影响,模拟分析了SOFC在不同条件下的工作参数变化对系统性能的影响。 Solid Oxide Fuel Cell(SOFC) is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or other oxidizing agents.In order to investigate the variable load performance,one dimensional steady and unsteady distributed parameter model for plate SOFC is developed using MATLAB software.The developed model fully considers the coupling effects of heat and mass transfer,fluid flow,chemical and electrochemical reaction,and the effects of operation parameters variations on the system performance are investigated.
