PROBLEM TO BE SOLVED: To prevent carbon deposition in a system even in an environment easy to deposit carbon like a fuel cell module wherein the flow of a fuel gas is slow, the resident time of the fuel gas is long, and a passage at low temperature is present, when a gas containing a high ratio of carbon constituent like a gasifying gas is used. SOLUTION: This fuel cell module provided with a reformer 2, a fuel cell module body 1 and a moisture feeder 6 is used. The reformer 2 reforms the fuel gas of a gasifying gas fed from a gasifying furnace 16. The module body 1 generates power by using the reformed fuel gas and an oxidizer gas. The moisture feeder 6 condenses moisture included in an exhausted fuel gas delivered from the module body 1, and converts the obtained water into steam to deliver it. The reformer 2 executes the reform by using the steam 56 delivered from the moisture feeder 6. COPYRIGHT: (C)2004,JPO
