Anode-supported cells were fabricated with optimized cathodes showing high power density of at under a cell voltage of and an active area of . A microstructure study was performed on such cell using a field-emission gun scanning electron microscope, which revealed that the (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 . The degree of contact between cathode and electrolyte is 39% on average.
