评估管式分段串联 (SIS) 固体氧化物燃料电池 (SOFC) 的运行特性对于设计、制备、集成和运行管式电池和电池组具有重要的指导意义。本研究考察了 30-电池管式 SIS SOFC，并评估了其物理参数的分布，例如轴向电压和温度。以及在电流、气流、阳极惰性气体流量 (N2)、阳极入口温度 (Tain)、阴极入口温度 (Tcin) 和氢气流量等敏感干扰下的运行特性，并提出了电池平均表面温度 (Tavercs) 的表征方程。结果表明，管式 SIS SOFC 轴向电化学反应不均匀，反应强度、电压和温度沿燃料流动方向降低。
研究亮点包括：
提出管式SOFC表面平均温度的表征方程。
明确管式SOFC的温度和电压轴向分布。
揭示30单元管式SIS SOFC的实验运行特性。

Abstract: Evaluating the operating characteristics of tubular segmented-in-series(SIS) solid oxide fuel cells (SOFCs) holds significant guiding value for designing, preparing, integrating, and operating tubular cells and stacks. This study examines a 30-cell tubular SIS SOFC and assesses the distribution of its physical parameters, such as axial voltage and temperature. As well as the operating characteristics under sensitive disturbances such as current, airflow, anode inert gas flow (N2), anode inlet temperature(Tain), cathode inlet temperature(Tcin), and hydrogen flow, and proposes a characterization equation for the cell average surface temperature(Tavercs). The results indicate heterogeneity in the axial electrochemical reactions of tubular SIS SOFC and the reaction intensity, voltage, and temperature, decrease along the direction of the fuel flow.
