Abstract
Abstract In this study?nanocomposites of LaCePr-oxide (LCP) and Ni0.8Co0.15Al0.05LiO2-? (NCAL) with different contents of polyvinylidene fluoride (PVDF) were prepared and applied to solid oxide fuel cells. The composite materials were characterized by X-ray diffraction analysis (XRD), scanning electron microscope (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and electrochemical impedance spectrum (EIS). The effect of {PVDF} concentration on the conductivity and performance of the fuel cells was investigated. It was found that {PVDF} plays a template role of pore forming in the nanocomposites, and the changed microstructure by as-formed pores greatly influences the electrochemical property of the nanocomposites. The cell with 3 wt% {PVDF} heat-treated at 210
