PURPOSE:To feed the reformed gas to a heated fuel cell at good timing so that no harmful effect is given to the electrode catalyst of a fuel cell by the carbon monoxide concentration in the reformed gas from a heated carbon monoxide converter when a fuel cell power generating device is started. CONSTITUTION:The relation between the carbon monoxide concentration in the reformed gas detected by a concentration detector 30 and the temperature of a fuel cell main body 5 detected by a temperature detector 6 is stored in a memory section 31, and the relation between the carbon monoxide concentration giving no harmful effect to an electrode catalyst and the temperature of the fuel cell main body 5 is read out. When no effect is given, an electric valve 13 is closed and electric valves 11, 16, 18 are opened by a controller 32, and the reformed gas and air are fed to the fuel cell main body 5. |
