Mount structure of a fuel cell stack holds the fuel cell stack in a motor room of a vehicle by side mounts and a rear mount. The fuel cell stack includes a plurality of power generation cells and a stack case. A window frame having a rear window is provided in a rear surface of the stack case. A device of the fuel cell system can be inserted into the rear window. The rear mount includes a rear mount bracket attached to a window frame. The rear mount bracket is positioned is below a vehicle body frame and a rear window.

A fuel cell system includes a fuel cell stack and a stack case. Curved portions are formed at corners of a first end plate. An upper plate includes curving sections facing the curved portions of the first end plate. An upper seal member is partially interposed between the curved portions of the first end plate and the curving sections of the upper plate.

A fuel cell vehicle includes tanks configured to store a fuel gas to be supplied to the fuel cell, the tanks being respectively disposed in front of and behind the motor drive unit such that a longitudinal direction of each of the tanks corresponds to a width direction of the fuel cell vehicle. The tanks are disposed such that respective end portions of the tanks on a side on which the high-voltage wiring portion is positioned are outside the high-voltage wiring portion in the width direction of the fuel cell vehicle and the respective end portions of tanks overlap a tire-wheel assembly in a front-rear direction of the fuel cell vehicle.

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 vehicle front structure includes a pair of front side members, the front side members being respectively placed on the right side and on the left side in a vehicle width direction in a vehicle front space ahead of a vehicle cabin space in a vehicle, so as to extend in a vehicle front-rear direction. A fuel cell unit is placed in a region sectioned by the front side members in the vehicle front space. A high-voltage component is placed above the front side members, and an inner edge portion of the high-voltage component in the vehicle width direction is placed outwardly in the vehicle width direction from an inner edge portion of the front side member in the vehicle width direction.
