Anode-supported cells were fabricated with optimized cathodes showing high power density of 1.2 W/cm(2) at 800 C under a cell voltage of 0.7 V and an active area of 4 x 4 cm. A microstructure study was performed on such cell using a field-emission gun scanning electron microscope, which revealed that the (La1-xSrx)(y)MnO3 +/-delta (LSM) composite cathodes consist of a network of homogenously distributed LSM, yttria-stabilized zirconia (YSZ), and pores. The individual grain size of LSM or YSZ is approximately 100 nm. The degree of contact between cathode and electrolyte is 39% on average. (c) 2005 The Electrochemical Society.
