摘要： A fuel cell is provided that includes a cell stack having a plurality of unit cells stacked in a first direction. An enclosure is disposed to surround the cell stack and includes an inlet that suctions external air and an outlet that discharges air that has been suctioned through the inlet and has circulated in the space between the cell stack and the enclosure. An insulating member is disposed to extend in the first direction in the space between an outer surface of the cell stack and an inner surface of the enclosure. The insulating member divides the space into a plurality of spaces and has an aperture formed therein to provide communication between the divided plurality of spaces, and an air intake member configured to suction air discharged from the outlet.

摘要： A fuel pressure regulator unit is mounted on a manifold. The fuel pressure regulator unit includes a housing providing a fuel inlet passage, a regulated fuel outlet passage, a sense pressure passage, a recycle passage and a mixed fuel passage. A pressure regulator is provided in the housing and is arranged fluidly between the fuel inlet passage and the regulated fuel outlet passage. The sense passage fluidly interconnects the mixed fuel passage and the pressure regulator. The pressure regulator is configured to regulate the flow of fuel from the fuel inlet passage to regulated fuel passage in response to a pressure from the sense pressure passage. An ejector is arranged within the housing and fluidly between the regulated fuel outlet passage and the mixed fuel passage. An ejector is configured to receive recycled fuel from the recycle passage.

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.

摘要： A fuel cell stack FS includes: a stack A that includes a single cells C that are stacked, each of the single cells including a frame 2 that holds an outer periphery of a membrane electrode assembly 1 and a pair of separators 3, 4 sandwiching the membrane electrode assembly 1 and the frame 2; and a case 50 that houses the stack A. The frame 2 comprises a protrusion 11 that protrudes outward from an outer periphery of a frame body 2A beyond an outer peripheral edge of the pair of separators 3, 4. A protrusion length of the protrusion 11 is greater than at least a gap between the frame 2 and one of the pair of separators 3, 4, and the protrusion 11 is bendable with respect to the frame body 2A. The protrusions prevent a contact between the separators 3, 4 of the single cell C and a contact between the end faces of the separators 3, 4 and the case 50 so as to prevent a short circuit of the single cell C.

摘要： An end plate of a fuel cell stack includes a metal plate body and a resin cover. The plate body includes a main portion, through holes extending through the main portion, and a flange portion including a fastening surface fastened to a flange of a case. The main portion includes a peripheral surface including a peripheral recess and an inner end surface that projects toward the inner side from the fastening surface. The cover includes an inner portion, a peripheral portion that covers the peripheral surface of the main portion, and an opposing portion that covers an inner end surface of the flange portion and opposes the flange of the case. The peripheral portion includes a peripheral projection that fills the peripheral recess and restricts contraction of the peripheral portion toward the inner side.

摘要： In accordance with a fuel cell module, a cell stack is housed in a housing including a box and a lid, and the lid is provided with a first gas flow channel through which either one of oxygen containing gas and exhaust gas flows. Therefore, the configuration of the housing can be simplified. Since the lid is provided with the gas flow channel, an accommodation space inside the box can be enlarged, the cell stack can be easily housed inside the housing through an opening, and the fuel cell module can be easily assembled.
