In this paper, the dynamic characteristics of a single tubular solid oxide fuel cell were discussed. The single cell was put vertically inside an electric furnace, and the operating temperature inside the furnace was kept constant during the experiments. Hydrogen, nitrogen and steam mixture was supplied to the anode side channel. Air was supplied to the cathode side of the cell tube. The transient responses of the terminal voltage to the electric current reference value change were measured. Throughout the experiments, it was found that the cell voltage responds quickly to the current change. The effect of the fuel utilization, i.e. fuel flow rate, on the voltage response pattern was not remarkable. In the case of the constant fuel utilization, the fuel flow rate was changed during the current change. This type of the fuel supply operation causes the response delay of the cell voltage.
