本文介绍了原始结果的热成像阳极表面的全尺寸固体氧化物燃料电池（SOFC）在运行过程中。在该工作中，使用了具有圆形形状和100 mm直径的市售燃料电池。测定被测电池阳极表面发射率是一种新方法。在300-800 °C温度范围内测定了燃料电池阳极表面的发射率为0.95 - 0.48，并给出了空载电池阳极表面的轮廓和温度分布。在操作期间测定电池的表面温度，并且极性从OCV（开路电压）变化到0.0V。结果表明，电池自热效应随电池温度的升高而减小。
The paper presents the original results of thermal imaging of the anodic surface of a full-size solid oxide fuel cell (SOFC) during operation. In this work, a commercially available fuel cell with a circular shape and a diameter of 100 mm was used. It is new to determine the emissivity of the anode surface of the tested cell. The emissivity of the anodic surface of the fuel cell was determined to be from 0.95 to 0.48 in the temperature range 300–800 °C and the profile and temperature distribution of the anodic surface of the unloaded cell was given. The surface temperature of the cell was determined during operation and the polarity changes from OCV (open circuit voltage) to 0.0 V. It was found that the cell self-heating effect decreases with increasing temperature of the cell.
