PROBLEM TO BE SOLVED: To provide a "horizontal-stripe" fuel cell structure which hardly causes the deformation of a support substrate when the support substrate is applied with external force.SOLUTION: A plurality of power generation element parts A electrically connected in series with one another are arranged at predetermined intervals in the longitudinal direction on upper and lower surfaces of a flat plate-like support substrate 10 having the longitudinal direction where a fuel gas channel 11 is formed in the inside. On the upper and lower surfaces of the support substrate 10, a plurality of recesses 12 are formed at predetermined intervals in the longitudinal direction. Each of the recess 12 is a rectangular parallelepiped hollow defined by four side walls closed in the circumferential direction and a bottom wall. A fuel electrode 20 of the corresponding power generation element part A is embedded in each recess 12. The fuel gas channel 11 passes through a plane parallel to the principal surface of the support substrate 10, and an inlet port and an outlet port of the fuel gas channel 11 are formed on one end in the longitudinal direction of the support substrate 10. |
