Popis:	We have developed a 1 kW class solid oxide fuel cell (SOFC) stack composed of 40-50 anode supported planar 120-mm-diameter SOFCs. The 50-cell stack provided an electrical conversion efficiency of 53.4% (based on the lower heating value (LHV) of the methane used as a fuel) and an output of 1120 W when the fuel utilization, current density, and operating temperature were 67%, 0.28 A cm-2, and 1073 K, respectively. The stack operated stably for almost 700 hours. Moreover, the 40-cell stack provided an electrical conversion efficiency of 63.9% (LHV) and an output of 1560 W when the fuel utilization, current density, and operating temperature were 85%, 0.53 A cm-2, and 1073 K, respectively.
