Abstract
ⶠUrgent publication is justified due to the rapid pace of development in the fabrication and application of solid oxide fuel cells (SOFCs). We have demonstrated long-term testing of microtubular SOFCs at intermediate temperature operations. The small-scale SOFCs supported by a microtubular NiO-GDC anode, which were developed in this study, generated very high power density of 150 mW cmâ2 and 340 mW cmâ2 at 500 °C and 550 °C, respectively, under the operation conditions of 0.7 V. The cell exhibited good stability with a degradation rate of 0.25%/100 h under operation conditions of 200 mA and 0.75 V.
