Original Paper


Novel NiCo2O4 nanoarrays have been in-situ grown on a La0.8Sr0.2MnO3-δ(LSM) cathode through a hydrothermal method, which presents the enhanced electrochemical performances of the LSM cathode for the intermediate temperature solid oxide fuel cells. XRD and SEM have been used to characterize phase structure and morphology of NiCo2O4 nanoarrays. The LSM cathode, modified by the NiCo2O4 nanoarrays, exhibits excellent electrochemical performances compared with the bare LSM cathode. The maximum peak power density of single cell, based on the NiCo2O4 nanoarrays modified the LSM cathode, reaches 957 mW cm−2 at 800 °C, which is almost two times higher than that for the cell based on the bare LSM cathode.
