A segmented-in-series solid oxide fuel cell stack of the invention comprises: an electrically-insulating porous support body having a gas passage therein; and a plurality of fuel cells arranged side by side on a surface of the support body. Each fuel cell have a first inner electrode layer; a current collector and a second inner electrode layer arranged side by side on the first inner electrode layer; and a solid electrolyte layer and an outer electrode layer sequentially laminated on the second inner electrode layer, and have a multilayer structure in which the solid electrolyte layer is extended and connected to the current collector through an intermediate layer. These fuel cells are connected in series. The current collector and the second inner electrode layer are arranged with a predetermined clearance therebetween on the first inner electrode layer. A fuel cell of the invention is formed by storing these segmented-in-series solid oxide fuel cell stacks in a storage container.
