Abstract: A fuel cell system including a fuel cell, an off-gas reprocessing unit that is provided downstream of the fuel cell and that at least partially removes at least one of steam or carbon dioxide from an off-gas discharged from the fuel cell, a flow passage that is provided downstream of the off-gas reprocessing unit and that allows a reprocessed off-gas discharged from the off-gas reprocessing unit to flow therethrough, and a controlling unit that modulates the reaction constant Kpa of a reaction A with respect to the reprocessed off-gas discharged from the off-gas reprocessing unit, to 1.22 or more.

Abstract: A protector includes: a main body part including an accommodation part which accommodates an electric wire bundle; a cover part which is attached to the main body part and covers the accommodation part; and a clamp which is formed on the main body part and is inserted into a locking hole formed in a mounting target part to lock the mounting target part. The protector further includes a pressing piece which is formed on a side of the main body part opposite to the clamp, extends along a plane perpendicular to an axis of the clamp, and is disposed at a position laterally deviating from the axis of the clamp.

Abstract: A solid oxide fuel cell stack has a surface from which via conductors for drawing a current are exposed. Collector plates are disposed on the surfaces of the fuel cell stack so that one main surface of the collector plates faces the via conductors. Fixing plates are fixed to the collector plates. Spacers are disposed between the fuel cell stack and the fixing plates. An adhesive fixes the fixing plates to the fuel cell stack through the spacers.

Abstract: 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.
