There is provided a fuel cell comprising a cell stacked body and a case configured to surround at least stacked body side faces of the cell stacked body. The case comprises a first case configured to include a first case side wall and a pair of first opposed side walls that are arranged to rise from a circumference of the first case side wall such as to have a draft angle; and a second case configured to include a second case side wall and a pair of second opposed side walls that are arranged to rise from a circumference of the second case side wall such as to have a draft angle. A first edge of each of the first opposed side walls is joined with a second edge of each of the second opposed side walls. This configuration suppresses size expansion of the fuel cell.

A fuel cell stack includes a cell stack body and a terminal plate and an insulator disposed at an end of the cell stack body in a stacking direction. The cell stack body includes a plurality of stacked power generation cells. Each of the power generation cells includes a membrane electrode assembly and a separator. The terminal plate is disposed between the cell stack body and the insulator. Elastic structure which elastically presses the terminal plate toward the cell stack body is provided between the insulator and the terminal plate.

A fuel cell includes a fuel cell stacked body in which a plurality of fuel cells are stacked in a first direction, a pair of end plates which sandwiches the fuel cell stacked body in the first direction, and a load measurement unit that is disposed between at least one of the pair of end plates and the fuel cell stacked body, and detects an electrode load, which acts on a power generation surface of the fuel cells, in the first direction. The load measurement unit includes a first conductive material, second conducive materials between which the first conductive material is interposed in the first direction, and which include a contact portion that is in contact with the first conductive material, and a detection unit that detects a voltage drop between the second conductive materials, which face each other in the first direction, with the first conductive material interposed therebetween.

A plate includes a working face and a header portion. The working face defines a plurality of reactant channels thereon. The header portion is disposed in a peripheral area of the plate and includes a plurality of flanges and a plurality of beads. The flanges are disposed on the header portion and define a plurality of apertures through the plate. Each flange defines a respective one of the apertures. At least one of the apertures is fluidly connected to the reactant channels. The plurality of beads is disposed on the working face. Each bead is disposed about a respective one of the apertures and thereby defines a respective one of the flanges. Each bead defines a shape consisting of bead-corners and bead-sides. Each bead has a sealing surface thereon. The sealing surface is configured to deflect when exposed to a contact pressure to thereby provide a substantially fluid-tight seal.

There is provided a fuel cell mounting structure including: a pair of left and right vibration-proofing members that are provided due to front side joining portions and rear side joining portions being mounted to suspension members; and a fuel cell that is supported at least by the pair of left and right vibration-proofing members, and is disposed at vehicle body upper sides of the suspension members, wherein one of the front side joining portions and the rear side joining portions are supported so as to be rotatable with a vehicle transverse direction being an axis of rotation, and another of the front side joining portions and the rear side joining portions are structured so as to break away from the suspension members, due to weak portions breaking at a time when load is inputted to the fuel cell from a vehicle body longitudinal direction.

A domestic power plant has a housing which has an external air connection and an output air connection, and comprises a ventilation device with a heat exchanger. The ventilation device is connected to the external air connection such that external air can flow in a first air tract via the heat exchanger, or via an external air bypass past the heat exchanger, into a feed air tract of the domestic power plant. The feed air tract runs at least partially within the housing. The domestic power plant also has an exhaust air tract in which an air volume flow, brought about by the ventilation device, can be propagated within the housing and a fuel cell unit.
