Abstract

In this study, we will report our investigation for La _0.75Sr_0.25Cr_0.5Mn_0.5O _3-δ (LSCrM) based anodes impregnated with solutions of cobalt (Co) nitrate. A YSZ supported SOFC with pure LSCrM anode and La _0.7Sr_0.3MnO₃ (LSM) cathode exhibits the maximum power density (P_max) of 58.7 and 5.2 mW cm^-2 at 850 °C in dry H₂ and dry CH₄. After the modification of anode with Co nitrate, the P_max reaches 196.2 mW cm^-2 in dry H₂ and 28.5 mW cm^-2 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.
