Abstract
In this study, we will report our investigation for La0.75Sr0.25Cr0.5Mn0.5O3âδ (LSCrM) based anodes impregnated with solutions of cobalt (Co) nitrate. A YSZ supported SOFC with pure LSCrM anode and La0.7Sr0.3MnO3 (LSM) cathode exhibits the maximum power density (Pmax) of 58.7 and 5.2 mW cmâ2 at 850 °C in dry H2 and dry CH4. After the modification of anode with Co nitrate, the Pmax reaches 196.2 mW cmâ2 in dry H2 and 28.5 mW cmâ2 in dry CH4, about 3.34 times and 5.48 times increase, respectively. These results indicate that Co is also a potential catalyst for LSCrM anode. Moreover, the effect of impregnation amount of catalyst on the cell performance is also evaluated in this study.
