In this paper, one step method was investigated to prepare La0.4Sr0.6Co0.2Fe0.7Nb0.1O3-δ-Gd0.2Ce0.8O2-δ (LSCFN-CGO) compound symmetrical electrode, La0.8Sr0.2Ga0.83Mg0.17O3-δ (LSGM) was used as electrolyte and symmetrical cells with a con?guration of LSCFN-CGO||LSGM||LSCFN-CGO were successfully fabricated. Phase-analysis and electrode microstructure of LSCFN-CGO were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). LSCFN-CGO was identified to be pure phase and perovskite structured LSCFN chemically compatible with ?uorite structured CGO. Using H2 (3% H2O) and C3H8 (3% H2O) as fuel for the cell, the maximum power densities were 980 mW/cm2 and 869 mW/cm2 at 850 ℃. Moreover, the long-term stability of the cell is demonstrated to be stable for 420 h under constant current of 0.3 A/cm2 using C3H8 (3% H2O) as fuel, 8 redox cycles were carried out, and the symmetrical electrode had ideal redox regeneration ability under carbon-based fuel. Results show that, one step method is a facile and optimized electrode fabrication procedure and owns promising application prospects.
