PURPOSE: To continue operation of a fuel cell main body by switching to emergency-use liquid fuel even when regular gaseous fuel is cut off. CONSTITUTION: When the supply of city gas is cut off and operation of a fuel cell main body 13 is continued by switching to methanol 26, the total amount of carbon atoms of fuel on the inlet side of an ejector 5 is detected with a first gas analyzer 40, and the total amount of carbon atoms of vaporized methanol is detected with a second gas analyzer 41. The total amount of carbon atoms detected with the second gas analyzer 41 is set as a target value, and the total amount of carbon atoms detected with the first gas analyzer 40 is used as reference to move a control mode and a control variable of the ejector 5. |
