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(T_ain), cathode inlet temperature(T_cin), and hydrogen flow, and proposes a characterization equation for the cell average surface temperature(T_avercs). 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.

30 芯管式分段串联固体氧化物燃料电池的实验运行特性

评估管式串联（SIS）固体氧化物燃料电池（SOFC）的运行特性对管式电池和电池堆的设计、准备、集成和运行具有重要的指导意义。本研究考察了 30 芯管式 SIS SOFC，并评估了其物理参数的分布，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 的轴向电化学反应具有异质性，反应强度、电压和温度沿燃料流方向降低。
