Paper Title:
Research on LSCMCo-CDC Composites as Improved Anode Material for IT-SOFC
  Abstract

La1-xSrxCr1-yMnyO3-δ(LSCM) has unique advantages over the traditional anodes for it’s stability and high catalytic activity being an anode of solid oxide fuel cell(SOFC). Doped cerium material and Co element are used to improve the conductivity both in oxidative and reductive conditions. La0.7Sr0.3Cr0.5Mn0.5-xCoxO3-δ-Ce0.8Ca0.2O2(LSCMCo-CDC) composite anode materials are synthesized in one-step by glycine nitrate process(GNP). X-ray diffraction patterns(XRD), scanning electron microscopy(SEM) and energy dispersive X-ray spectroscopy(EDS) are used to characterize the powders. The conductivity of LSCMCo-CDC increases with increasing the quantity of Co when the temperature is above 750°C, and the maximum values are 10.5 Scm-1 and 0.7 Scm-1 of LSCMCo0.15-CDC at 800°C in air and H2 atmosphere, respectively. It’s conductivity in intermediate temperature have been promoted obviously comparing to that of LSCM-CDC and LSCMCo. Good chemical compatibility between LSCMCo-CDC and La0.9Sr0.1Ga0.8Mg0.2O3-δ(LSGM) is confirmed by XRD results.
