摘　　要：固体氧化物燃料电池(Solid Oxide Fuel Cells,SOFCs)具有燃料适用性广、余热利用价值高、能量转化效率高的优点,成为当下能量转化技术的研究热点。但是,在商业化之前,SOFCs仍然存在着一些亟待改善的问题,其中,稳定性和工作寿命便是最关键的问题。鉴于流场与温度场、电场相互耦合,不均匀的流场极易导致电池局部热失控,产生热应力,对电池产生不可逆损坏,影响SOFCs系统寿命。改善流场设计、保证流动均匀性是提高稳定性和寿命的关键。对平板型SOFCs的流场设计及优化进行了概述。Solid Oxide Fuel Cells(SOFCs)are energy conversion devices,which have various advantages,such as wide fuel applicability,high energy conversion efficiency and easy utilization of waste heat.However,SOFCs still have problems for commercialization,such as low stability and short working life.Due to the interaction of flow field,temperature field and electric field,the non-uniform flow field can easily lead to local temperature gradient and thermal stress in single cells,which causes irreversible damage to the SOFCs stack.Optimizing the uniformity of the flow field is a key to improve the stability and life of SOFCs.This paper summarizes the flow field design and optimization of planar SOFCs stacks.
