    An intermediate temperature solid oxide fuel cell (SOFC) module was developed using electrochemically active cells composed of (La, Sr)(Ga, Mg, Co)O3 electrolyte, Ni-(Ce, Sm)O2 anode, and (Sm, Sr)CoO3 cathode. Seal-less planar type stack design was employed. The first generation module successfully provided the output power of 1 kW with thermal self-sustainability below 800°C. Maximum electrical efficiency obtained with this module was 43%[LHV] together with the corresponding fuel utilization of 78%. Dynamic performance tests demonstrated the capability of output power alteration from 0.6 to l kW while maintaining a high electrical conversion efficiency. Further testing and modification of the module for methane fuel utilization are in progress.
