PURPOSE:To prevent hindrance due to rapid heating of a cell to make temperature rise of the cell safe by raising temperature while retaining a temperature difference between an inlet and outlet of cathode gas within a predetermined range. CONSTITUTION:At the time of starting a fuel cell 3, a cathode gas inlet valve 2 and a cathode gas outlet valve 4 are fully closed so that a closed loop is formed of a cathode gas circulation line 6 and a cathode C, and cathod gas is circulated in this closed loop and heated by a heater 8. Gas temperature at a gas inlet of the closed loop is detected by a detector 12 while gas temperature at a gas outlet is detected by a detector 13, and respective detection signals are transmitted to a controller 14 to obtain a temperature difference between the inlet and outlet. A signal in accordance with this temperature difference is transmitted to an adjuster 15 to adjust heaving quantity of the heater 8 so as to raise temperature while retaining the temperature difference within a perdetermined range. |
