<P>PROBLEM TO BE SOLVED: To provide a fuel cell with a simple and economic constitution, capable of avoiding influence of exhaust gas exhausted in an outer peripheral direction of an electrolyte/electrode junction, with enhanced power generating efficiency, aiming at improvement of fuel utilization efficiency. <P>SOLUTION: The fuel cell is composed of a plurality of electrolyte/electrode junction 56 interposed between a set of separators. The electrolyte/electrode junction 56 is formed by arranging a cathode electrode 52 and an anode electrode 54 on both faces of the electrolyte 50. The surface area of the cathode electrode 52 is set smaller than that of the anode electrode 54, concretely, the diameter D1 of the cathode electrode 52 is set smaller than the diameter D2 of the anode electrode 54. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
