摘要： A fuel cell stack includes a plurality of power generation cells and an end plate. A plurality of fluid passages for allowing a fuel gas, an oxygen-containing gas, and a coolant to flow independently in a stacking direction are provided in the plurality of power generation cells. The end plate includes: holes which penetrate through the end plate in a thickness direction and are connected to the fluid passages, and to which manifolds are connected; and flow channels formed in the end plate, and connected to the fluid passages. The flow channels include first and second lateral openings opened to a surface which is different from a surface where the holes are opened.

摘要： A reactant gas channel part provided outside an auxiliary machinery case of a fuel cell system is connected to a case through hole. A plurality of channel seal members are provided between the auxiliary machinery case and the reactant gas channel part, where the channel seal members are arranged side by side in the radial direction of the case through hole and surround the case through hole. The reactant gas channel part has an opposing surface that faces a surrounding portion of the auxiliary machinery case that surrounds the case through hole. The channel seal members include an inner seal member abutting on the opposing surface and an outer seal member disposed radially outside of it. A connection channel communicating with an internal space of the auxiliary machinery case is formed between the inner seal member and the outer seal member.

摘要： A fuel cell module includes a case body containing a cell stack body formed by stacking a plurality of power generation cells. The case body includes a plurality of connectors for mounting the fuel cell module into a fuel cell vehicle. The plurality of connectors include a first connector group used for mounting the fuel cell module into a first fuel cell vehicle in a manner that a stacking direction of the fuel cell module is substantially aligned with a first direction, and a second connector group used for mounting the fuel cell module into a second fuel cell vehicle in a manner that the stacking direction of the fuel cell module is substantially aligned with a second direction. Some connectors are common to both the first connector group and the second connector group.
