<P>PROBLEM TO BE SOLVED: To provide a single chamber type solid-oxide fuel cell in which the number of cell stages is suppressed when it is stacked up and which is small in size and capable of a large output, and to provide its stack structure. <P>SOLUTION: The solid-oxide fuel cell includes at least one support body with gas permeability in which at least one first through-hole and at least one second through-hole extending in the same axial direction are formed and the first and the second through-holes are opened at both ends, a first unit cell in which a fuel electrode, an electrolyte, and an air electrode are laminated in order on the inner wall face of each first through-hole, and a second unit cell in which an air electrode, an electrolyte, and a fuel electrode are laminated in this order on the inner wall face of the second through-hole. The fuel electrodes, the air electrodes, and the electrolyte have gas permeability, and in each of unit cells, the fuel electrode and the air electrode are laminated so as not to be in contact. <P>COPYRIGHT: (C)2010,JPO&INPIT |
