The performance of a conventional anode‐supported microtubular SOFC using doped ceria as an electrolyte and N i‐based cermet as an anode is evaluated at low operating temperature between 294 and 542°C. An open‐circuit voltage ( OCV ) of >0.9 V is obtained at all measured operating temperatures, and power generation is observed at temperatures as low as 294°C. The power density of the cell is 0.6 W/cm 2 at 542°C operating temperature with 47% fuel utilization and is 5 mW/cm 2 at 294°C operating temperature with an open‐circuit voltage of 0.95 V. According to impedance spectroscopy, a greater influence of gas flow rate, on the cell performance, is observed at higher operating temperature.
