<P>PROBLEM TO BE SOLVED: To provide a fuel cell cogeneration device in which a reformer is made to have an optimum state, reduction or the like of reforming efficiency is prevented, and driving efficiency as the whole device is improved even in the case a power generating state of a fuel cell changes. <P>SOLUTION: In an anode off gas supplying passage 40 to supply the anode off gas discharged from the fuel cell 12 by connecting the fuel cell 12 to the reformer 34 to the reformer 34 as a fuel for heating a reforming catalyst, a flow rate of the anode off gas supplied to the reformer 34 is adjusted by a flow rate adjusting valve 82, and the reforming catalyst is retained at a prescribed temperature. Moreover, out of the anode off gas connected to a branch route 84 branched from the anode off gas supplying passage 40 and discharged from the fuel cell 12, this is equipped with a burner 90 in which the anode off gas exceeding in an amount necessary for retaining the reforming catalyst at the prescribed temperature is combusted, and a heat exchanger 92 is equipped which is connected to the burner 90 and in which heat generated by combustion in the burner 90 is recollected. <P>COPYRIGHT: (C)2009,JPO&INPIT |
