Mg0.4Zn0.6O/Ce0.8Sm0.2O2 deLi0.3Ni0.6Cu0.07Sr0.03O2 d layer

Electrolyte-free fuel cell (EFFC) which holds the similar function with the traditional solid oxide fuel cell (SOFC) but possesses a completely different structure, has draw much attention during these years. Herein, we report a complex of MZSDCeLNCS (Mg0.4Zn0.6O/Ce0.8Sm0.2O2� deLi0.3Ni0.6Cu0.07Sr0.03O2� d) for EFFC that demonstrates a high electrochemical power output of about 600 mW cm � 2 at 630 � C. The co- doped MZSDC is synthesized by a co-precipitation method. Semiconductor material of LNCS is synthe- sized by direct solid state reaction. The microstructure and morphology of the composite materials are characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and energy-dispersive X- ray spectrometer (EDS). The performance of the cell with a large size (6 � 6c m 2 ) is comparable or even better than that of the conventional solid oxide fuel cells with large sizes. The maximum power output of 9.28 W is obtained from the large-size cell at 600 � C. This paper develops a new functional nano- composite for EFFC which is conducive to its commercial use.
