<P>PROBLEM TO BE SOLVED: To make a fuel reformer superbly perform reforming reaction, even at the time of large output fluctuation. <P>SOLUTION: A fuel cell includes a fuel cell 10 provided with an anode 12 and a cathode 13, the fuel reformer 40 to reform raw fuel to be fed to the anode 12, a combustor 20 to form heating gas, an exhaust hydrogen-containing gas feeding passage 12c to which the heating gas exhausted from the combustor 20 is fed and which is provided with a heat exchanger 30 which exchanges heat of the fuel reformer 40 as well as feeds the exhaust hydrogen-containing gas to the combustor, an oxygen-containing gas exhausting passage 13b for exhausting the oxygen containing gas exhausted from the cathode 13 to outside, and an oxygen-containing gas branch-feeding passage 13c to branch-feed a portion of the exhaust oxygen-containing gas exhausted from the cathode to the combustor 20. <P>COPYRIGHT: (C)2010,JPO&INPIT |
