A fuel cell vehicle capable of preventing illegally access by using a tool to a piping fitting connecting fuel piping and a valve module to each other without increasing the number of components. The fuel cell vehicle includes an electric motor, a fuel cell supported by a frame to supply electric power to the electric motor, a fuel tank supported by the frame to store fuel to be supplied to the fuel cell, a valve module disposed below a cross member and behind the fuel tank, and a piping fitting connecting fuel piping to the valve module. The valve module includes a cut-out stepped portion provided in a side-face side of an upper portion of the valve module. The piping fitting is attached to the cut-out side face, the piping fitting being disposed between the cross member and the cut-out top face in a vehicle vertical direction.

Fuel cell vehicle

An object is to supply a sufficient amount of air to a fuel cell stack in a fuel cell vehicle when the fuel cell stack is mounted below a floor, the fuel cell stack configured to draw in air through an intake duct and discharge air to the exterior through an exhaust duct. An air introduction surface () faces upward or downward in a vehicle upper and lower direction, an intake passage portion () of the intake duct () extends along the air introduction surface () and vertical walls () of left and right end portions of the fuel cell stack () while a pair of air introduction ports () opens in left and right end portions of the intake passage portion (), and an exhaust passage portion () of the exhaust duct () extends along an air discharge surface () and vertical walls () of front and rear end portions of the fuel cell stack () while a pair of air discharge ports () opens in front and rear end portions of the exhaust passage portion ().

There is provided a saddle-ridden type fuel cell vehicle. The fuel cell vehicle includes: a body frame; a steerable wheel; a driving wheel; a motor; a fuel cell; a fuel tank; and a tank valve. The body frame includes: a head pipe; a down frame portion; a pair of upper main frame portions; a pair of lower main frame portions; and up frame portions. A tank placement portion is formed in a region encircled by the upper main frame portions and the lower main frame portions in the middle portion of the body frame in the front and rear direction. The fuel tank is placed on the tank placement portion so that an axis thereof extends in the front and rear direction. A guard frame is installed between the up frame portions to traverse the rear of the tank valve in a right and left direction.

Saddle-ridden type fuel cell vehicle

An object of the present invention is to efficiently mount a fuel cell system below a floor of a vehicle rear portion and to protect the fuel cell system when a forward impact force acts on a vehicle rear portion. To achieve this, a fuel cell vehicle in which a fuel cell system includes a gas tank is configured to store a fuel gas and a fuel cell unit formed by integrating a fuel cell stack, an intake duct, and an exhaust duct, the gas tank is disposed in a space below a rear floor connected to a front floor via a vertical wall portion and adjacent to the vertical wall portion, and the fuel cell unit is disposed behind the gas tank. In the fuel cell vehicle, an axle beam extending in a vehicle width direction and connecting left and right rear wheels to each other is disposed behind the gas tank, the fuel cell unit is disposed between the axle beam and a rear bumper, and vertical walls of front and rear portions of the fuel cell stack are covered with at least one of an upstream portion of the intake duct and a downstream portion of the exhaust duct.

A scooter-type motorcycle is provided with a fuel cell system for driving the motorcycle by an electric power and includes: a vehicle body including a pair of left and right upper frames extending in a longitudinal direction of the vehicle body and a pair of left and right lower frames extending in the longitudinal direction of the vehicle body and having rear side end portions bent and connected to the respective upper frames; a fuel cell mounted on the vehicle body; a fuel tank connected to the fuel cell, in which the fuel tank is disposed in a center tunnel surrounded by the upper frames and the lower frames. A pair of left and right upper frames and a pair of left and right lower frames constitute a fuel tank supporting structure.
