    摘要： A flat plate laminated type high-temperature fuel cell, with internal manifold structure, has a laminated body constructed by alternately laminating power generation cells (5) and separators (8), and by applying a load to the laminated body in the laminating direction to compress elements of the laminated body. Each separator (8) has a connecting section (8b) for connecting a manifold section (8a) of the separator (8) and a section (8c) at which the power generation cell (5) is located, and the connecting section (8b) has flexibility to the load. Thus, it is possible to improve adhesiveness in the power generating section of the fuel cell stack and gas seal performance in the manifold section. Further, each of separators (108) has through-holes (122) extending in the laminating direction, and a fixing rod (123) is inserted into each of the through-holes (122) for restricting movements of the separators (108) in a plane direction due to thermal strain in operation. Thus, the movements of the separators due to thermal strain under high temperature atmosphere at power generation can be restricted and damage to the power generation cells can be prevented.
