<P>PROBLEM TO BE SOLVED: To improve utilization efficiency of energy in a fuel cell. <P>SOLUTION: The fuel cell main body 1 is provided with a collecting plate 2, a collecting plate 3, and a plurality of membrane electrode junctions 4 as well as a plurality of double-sided separators 5 alternately laminated between the collecting plate 2 and the collecting plate 3. An anode gas flow channel 71 is formed at one face of each double-sided separator, and a cathode gas flow channel at the other face. A combustion gas supply flow channel 74 communicated with the anode gas flow channel 71, a cathode gas supply flow channel 75 communicated with the cathode gas flow channel 76, and a heat exchange flow channel 73 communicated with the combustion gas supply flow channel 74 and the cathode gas supply flow channel 75, are formed on an inside face of each double-sided separator 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
