<P>PROBLEM TO BE SOLVED: To conduct efficient heat exchange and to enhance heat efficiency in compact and economical constitution. <P>SOLUTION: A fuel cell 11 is equipped with a pair of separators 28 interposing a plurality of electrolyte/electrode assemblies between them. A first projection part 48 forming a fuel gas passage 46 for supplying fuel gas in the arrow B1 direction along the electrode surface of an anode 24 and a second projection part 52 forming an oxidant gas passage 50 for supplying oxidant gas in the arrow B2 direction along the electrode surface of a cathode 22 are installed in the separators 28. A fuel gas supply passage 66 of an passage member 56 fixed to the separator 28 is communicated with a fuel gas induction port 54 formed in the inside edge part of a trapezoid part 36. Exhaust fuel gas exhausted from the fuel gas passage 46 to an oxidant gas supply part 68 after used for reaction in the anode 24 and contained hydrogen not yet burned are mixed with oxidant gas before use , and mixture gas is burned and then supplied to the oxidant gas passage 50. <P>COPYRIGHT: (C)2007,JPO&INPIT |
