在平面固体氧化物燃料电池（SOFC）中，燃料/氧化剂分布导致电极上的电流和温度分布，从而导致化学和热机械电池退化以及总电池性能和效率的衰减。本文重点研究开发实时异常诊断方法，以提高船用SOFC长期安全稳定运行所需的可靠性和耐久性.因此，我们解决了在平面内的空间电流和阻抗分布的原位测量沿着阳极支撑的平面固体氧化物燃料电池的流动通道的分段阴极相对于上，中间，和下游部分的阳极。
In planar solid oxide fuel cells (SOFCs), the fuel/oxidant distributions cause current and temperature distributions over the electrodes, giving chemical and thermo-mechanical cell degradations as well as decays in the total cell performance and efficiency. We focus on the development of real-time abnormaldiagnosis method to improve the reliability and durability required for the long-term safety and stable operation of the marine SOFC. We therefore address in-situ measurements of in-plane spatial current and impedance distributions along the flow channels of an anode-supported planar SOFC by segmented cathodes opposing to up, mid, and downstream parts of the anode.
