Abstract
A stack structure for a solid oxide fuel cell includes a plurality of stacked single cells, each having a fuel electrode layer including a fuel electrode and an air electrode layer including an air electrode, the fuel electrode layer and the air electrode layer being arranged opposite each other on either side of a solid electrolyte, separators arranged between the stacked single cells to separate the single cells, and non-porous seal parts located within the fuel electrode layer and the air electrode layer, are equivalent to either the separators or the solid electrolyte at least in terms of thermal expansion and contraction characteristics, and are integrated with an edge of the fuel electrode or an edge of the air electrode, and also with the adjacent separator and the adjacent solid electrolyte.
