Abstract	The proton-conducting reversible solid oxide cell (PC-RSOC) is one of the cleanest and most efficient energy conversion devices. At present, to reduce the polarization loss of PC-RSOCs at intermediate temperatures is key. In this work, a micro-nanostructured La1.2Sr0.8NiO4-delta (LSN).BaCe0.68Zr0.1Y0.1Yb0.1Cu0.02O3-delta (BCZYYC2) composite electrode is prepared by infiltration method. The impedance spectrum results of symmetrical cells indicate that the 42.2 wt% LSN-infiltrated BCZYYC2 electrode exhibits the lowest polarization resistance of 0.039 Omega cm(2) at 700 degrees C. Moreover, a hydrogen electrode-supported single cell with the 42.2 wt% LSN-infiltrated BCZYYC2 electrode shows a high maximum power density of 1.22 W cm(-2) and an electrolysis current density (at 1.3 V) of -3.02 A cm(-2) at 700 degrees C, respectively. These encouraging results suggest the applicability of the LSN-infiltrated BCZYYC2 as an oxygen electrode for high-performance PC-RSOCs.
