Provided is a method for producing a fuel cell that can reduce the amount of an adhesive applied to join a pair of sheet-like separators together while also avoiding failures in the conveyance of the separators. A separator, which has a bent portion on the peripheral edge thereof and has a recess and a projection formed on one surface and the other surface, respectively, of the separator by the bent portion, is used. The conveying step includes gripping the bent portion at opposite ends of each separator using grippers. The seal portion forming step includes disposing an adhesive in the recess formed by the bent portion of one of the separators, and fitting the projection formed by the bent portion of the other separator in the recess.

A dummy cell disposed at least at one end of a cell stack body in a fuel cell stack includes a dummy electrode assembly. The dummy electrode assembly includes a plate, and a pair of electrodes joined to both surfaces of the plate through adhesive layers, respectively. The adhesive layers are disposed only in a second area that lies outside a first area corresponding to a power generation area of a power generation cell in the dummy electrode assembly.

An integrated hydrogen-electric engine including an air compressor system, a hydrogen fuel source, a fuel cell stack, a heat exchanger, an elongated shaft, and a motor assembly. The heat exchanger is disposed in fluid communication with the hydrogen fuel source and the fuel cell stack. The elongated shaft supports the air compressor system, the fuel cell stack and the heat exchanger. The motor assembly is disposed in electrical communication with the fuel cell stack.

Systems and methods including a header flange to evenly distribute contact pressure across seals include, in some aspects, a plate including a bead and a flange edge. The bead includes a bead-side and a bead-corner. The flange edge defines an aperture through the plate. The flange edge also includes a first edge-portion proximate the bead-side and a second edge-portion proximate the bead-corner. The bead-side and the first edge-portion define a first edge-distance therebetween. The bead-corner and the second edge-portion define a second edge-distance therebetween. The second edge-distance is greater than the first edge-distance.

A fuel cell stack includes a first stack including a plurality of first fuel cells stacked on each other, and a second stack including a plurality of second fuel cells stacked on each other and disposed on one side of the first stack. Each of the first stack and the second stack includes a fuel inlet hole, through which fuel to be supplied to anodes of the respective first and second fuel cells is introduced, a fuel discharge hole, through which the fuel passing through the anodes is discharged, an air inlet hole, through which air to be supplied to cathodes of the respective first and second fuel cells is introduced, and an air discharge hole, through which the air passing through the cathodes is discharged. The fuel cell stack divided into the two stacks increases a charging ratio of hydrogen at the anodes of the respective stacks.

A vehicle installation structure for a fuel cell stack that includes: a framework member disposed at a vehicle lower side; a fuel cell stack that is disposed at a vehicle front section or a vehicle rear section, and that is elastically supported by the framework member via a vibration isolating member; and a drive motor that is disposed at a same section of the vehicle front section or the vehicle rear section as the fuel cell stack, that is separate from the fuel cell stack, and that is elastically supported by the framework member via a vibration isolating member such that a height position of at least one of an upper end, a lower end, or a height direction center of the drive motor is disposed between a height position of an upper end and a height position of a lower end of the fuel cell stack.

A fuel cell having an elastic member is provided. The fuel cell includes a cell stack in which a plurality of unit cells are stacked in a first direction and an end-plate disposed on each of opposite side ends of the cell stack. The elastic member is disposed in a portion of the end-plate to overlap a lower area of the cell stack in which condensate water remains in the first direction.
