On each of upper and lower surfaces of a flat-plate-like support substrate 10 having a longitudinal direction and having fuel gas flow channels 11 formed therein, a plurality of power-generating elements A connected electrically in series are disposed at predetermined intervals along the longitudinal direction. On each of the upper and lower surfaces of the support substrate 10, a plurality of recesses 12 are formed at predetermined intervals along the longitudinal direction. Each of the recesses 12 is a rectangular-parallelepiped-like depression defined by four side walls arranged in a circumferentially closed manner and a bottom wall. That is, in the support substrate 10, frames are formed to surround the respective recesses 12. Fuel electrodes 20 of the power-generating elements A are embedded in the respective recesses 12. In this manner, there can be provided a structure of a "segmented-in-series type" fuel cell in which, when a support substrate is subjected to an external force, the support substrate is unlikely to be deformed. |
