<P>PROBLEM TO BE SOLVED: To provide a low-cost fuel cell generator, and its operation method, with an excellent maintenance property by preventing high CO-concentration reformed gas from diffusing to a fuel cell main body. <P>SOLUTION: The device is to be provided with a reformer 3, the fuel cell main body 1, an exhaust hydrogen supply line 19, a reformed gas bypass line 18 having a battery bypass valve 10, a water sealing unit 12 consisting of a water storage part and a gas space part fitted in its upward, and a switching control device of gas flow channels drawn out from the fuel cell main body. The gas flow channels drawn out from the fuel cell main body in the exhaust hydrogen supply line are shut off by water of the water storage part of the water sealing unit before start of power generation, and are made communicated with a burner for the reformer via the gas space part of the water sealing unit after the start of the power generation. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
