Abstract

Abstract: In order to improve the polarization property of LSCN as an anode material of direct-hydrocarbon SOFC, the LSCN powder was mixed with nanometer SDC in weight ratio of 1:1. The conductivity and polarization properties of LSCN-SDC anode in H₂ and CH₄ atmospheres were examined and discussed, relating to the SEM morphologies. The interface structure between the anode and the YSZ electrolyte is obviously modified when nanometer SDC is added. The AC
impedance of the anode with SDC is only tenth of that without SDC, and the polarization property is greatly improved. After polarization test, no carbon species was observed from the microstructure morphology of the LSCN-SDC anode.

Key words: LSCN-SDC, microstructure, conductivity, polarization
