固体氧化物燃料电池SOFC（solid oxide fuel cell）的一致性和连接方式是影响电堆整体性能的重要因素。通过线性扫描伏安法、电化学阻抗谱等方法评价了扁管式SOFC堆内电池的一致性，并结合弛豫时间分布技术研究了一致性和连接方式对电堆输出性能的综合影响及潜在的电化学机理。结果表明，一致性和连接方式共同作用于电堆性能，一致性影响电堆寿命，连接方式影响电堆输出功率。在串联方式下，电池一致性低会使性能较差的电池过度放电，加速电堆的性能衰退。相较于串联，并联会造成较大功率损失，损失主要源自欧姆电阻及氧交换、电荷转移过程的影响，但其对电堆寿命的影响较小。综上所述，串联电堆峰值功率高，但一致性低时对电堆寿命影响较大；并联电堆的功率损失明显，但对电堆寿命的影响小。

The cell uniformity and connection mode of solid oxide fuel cell (SOFC) are important factors affecting the overall performance of the stack. The uniformity of flat-chip cells in the SOFC stack is evaluated by methods such as linear sweep voltammetry and electrochemical impedance spectroscopy. Then, the comprehensive effect of cell uniformity and connection mode on the stack's output performance and the underlying electrochemical mechanism are investigated by combining with the method of distribution of relaxation times. Results indicate that the cell uniformity and connection mode jointly affect the stack performance, i.e., the cell uniformity affects the stack lifetime, while the connection mode affects the stack's output power. In a series mode, a low cell uniformity will cause the poor-performance cell to over-discharge, which may accelerate the deterioration of the stack performance. Compared with the series mode, the parallel mode will cause a higher power loss, which mainly comes from ohm resistance, oxygen exchange and charge transfer processes but affects the stack lifetime to a small degree. In general, the peak power of the series stack is high, but the lifetime is greatly affected when the cell uniformity is low. The power loss of the parallel stack is obvious, but the influence on the stack lifetime is weak.
