<P>PROBLEM TO BE SOLVED: To provide a "segmented-in-series" fuel cell structure that has a support substrate with resistance to deformation when subjected to external force, the fuel cell structure preventing cracking or detachment of a fuel electrode. <P>SOLUTION: A flat substrate 10 has fuel gas channels 11 formed therein, and has a longitudinal direction. On each of an upper surface and a lower surface of the flat substrate 10, a plurality of power generating element sections A that are electrically connected in series are arranged at predetermined intervals in the longitudinal direction. On each of the upper and lower surfaces of the flat substrate 10, a plurality of depressions 12 are formed at predetermined intervals in the longitudinal direction. Each of the depressions 12 is a cuboid recess defined by four side walls that are circumferentially closed, and a bottom wall. In each depression 12, a fuel electrode 20 of the corresponding power generating element section A is buried. Each fuel electrode 20 includes: Ni or Ni oxide; and a rare-earth element oxide or an oxide that is expressed by the chemical formula AEZrO<SB POS="POST">3</SB>(where AE represents one element, or two or more elements, selected from the group consisting of Ca, Sr, Mg, and Ba). <P>COPYRIGHT: (C)2013,JPO&INPIT |
