The Preparation Research for IT-SOFC Anode Material LSCM

Abstract:

Perovskite-structure La0.7Sr0.3Cr0.5Mn0.5O3-δanode powder was prepared by glycine nitrate process. The result of characterization indicated that the pore morphology and mechanical property of anode support pellets using starch as pore-forming agent are superior to that of using activated carbon. The maximum value of porosity and specific surface area are 40%, 1.256m2/mg at 10MPa, respectively. The conductive mechanism is small-polaron conductive mechanism at low temperature, but it is metalloid conductive mechanism at high temperature.
