摘　　要：直接将燃料化学能转化为电能的固体氧化物燃料电池是一种高效的发电设备,是解决环境问题的有效途径。以固体氧化物燃料电池为研究对象,探索了阳极集流肋的构型设计对阻抗、放电性质等的影响。研究结果显示:合理排布阳极集流肋位置可以缩短电荷传输路径,增加阳极集流肋数量可以增大电接触表面,减小带电粒子的传导输运阻力,使欧姆极化下降,电池的放电功率得到提升。通过优化电池组件构型实现高效输运电荷是简易可行的方法。Solid oxide fuel cell, which directly converts fuel chemical energy into electric energy, is a kind of efficient power generation equipment and an effective way to solve environmental problems. In this paper, the influence of the configuration design of the anode collector fin on the impedance and discharge properties of solid oxide fuel cell was investigated. The results show that reasonable arrangement of anode collecting ribs can shorten the charge transmission path, increasing the number of anode collecting ribs can increase the electric contact surface, reduce the conduction and transport resistance of charged particles, reduce the ohmic polarization, and improve the discharge power of the battery. It is a simple and feasible method to realize efficient charge transport by optimizing the configuration of battery components.
