摘要：
PSCF3737(Pr0.3Sr0.7Co0.3Fe0.7O3) is a good candidate cathode material for IT-SOFC(intermediate temperature solid oxide fuel cell) because of high MIEC(mixed ionic electronic conductor) conductivity. In this study, the characteristics of PSCF3737 was investigated and optimizations of sintering temperature and thickness for PSCF3737(Pr0.3Sr0.7Co0.3Fe0.7O3) was carried out. Impedance responses were divided into two parts by frequency region. Middle frequency part (similar to 10(2) Hz) was concerned with oxygen reduction reaction on surface and low frequency part (similar to 10(-1) Hz) was related with oxygen diffusion. The reasonable sintering temperature and thickness of cathode were 1200 degrees C and about 27 mu m with regard to EIS(electrochemical impedance spectroscopy). ASR(areas specific resistance) of optimized cathode is 0.115 Omega . cm(2) at 700 degrees C.
