Abstract:
1. A stack structure for a solid oxide fuel cell, comprising: a plurality of stacked single cells, each comprising: a separator 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, wherein the non-porous seal parts are equivalent to either the separator 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 an adjacent separator and an adjacent solid electrolyte, wherein the stack structure is formed such that a stream of fuel gas is supplied to the fuel electrode and a stream of air gas is supplied to the air electrode respectively, and the non-porous seal parts are integrated with the edge of the fuel electrode or the edge of the air electrode, and also integrated with the adjacent separator and the adjacent solid electrolyte by sintering, and wherein at least one of the single cells in the stack does not have cell support.
