<P>PROBLEM TO BE SOLVED: To provide a fuel cell co-generation device in which a moisture content contained in anode gas is made optimal in accordance with an operation condition of a fuel cell and a deterioration of a power generation efficiency can be prevented. <P>SOLUTION: The fuel cell co-generation device is provided with a condensing unit (an anode gas heat exchanger 84) arranged in an anode gas supplying passage (a first anode gas supplying passage 62a), a fuel cell heat exchanger 100 to recover an exhausted heat generated in the fuel cell 12, and heat exchangers (an anode offgas heat exchanger 80, a cathode offgas heat exchanger 82) arranged at least in either of an anode offgas exhausting passage 64 and a cathode offgas exhausting passage 78. After a cooling water is supplied from the fuel cell heat exchanger to the heat exchangers through a first cooling water supplying passage 110, the cooling water is supplied to the condensing unit through a second cooling water supplying passage 114, namely, the cooling water with which the anode offgas and the cathode offgas are heat-exchanged in the heat exchanger is supplied to the condensing unit. <P>COPYRIGHT: (C)2009,JPO&INPIT |
