Fig. 1 shows a layout structure of a fuel cell system in a passenger car.

The interior space of the passenger car may be divided into a cab 110, a passenger car compartment 120, and a rear compartment 130 along the length direction. The fuel cell passenger car includes a fuel cell 200, a gas tank 300, and a radiator 400. These are conventional arrangements and will not be described in detail here.

In the present embodiment, the fuel cell 200, which supplies the power of the automobile, is disposed in the rear compartment 100 of the passenger car body, and the fuel cell 200 is mounted in the rear compartment floor skeleton region (lower region of the rear compartment) in the rear compartment.

In order to facilitate heat dissipation, a cooling water circulation system 210 is disposed outside the fuel cell 200, the radiator 400 is connected to a cooling pipe 211 of a circulating cooling water system, the cooling pipe is used to circulate cooling water as a cooling medium, an inlet of the radiator 400 is communicated with the outside, outside traveling wind enters from the inlet of the radiator 400, and the cooling water circulating in the cooling pipe is discharged from an air outlet after heat exchange is performed. The radiator 400 is fixedly arranged at the top of the rear cabin, and the radiator 400 is fixedly connected with the vehicle body framework; the radiator can adopt the existing radiator structure, and the details are not described herein.

The gas tank 300 stores therein gas fuel to be supplied to the fuel cell 200, and is disposed in a rear compartment of a passenger car body; in the present embodiment, the gaseous fuel is hydrogen.

The air tank 300 is cylindrical and is provided laterally in the rear compartment so that the longitudinal direction thereof is the vehicle width direction. However, the shape of the air tank 300 is not limited to a cylindrical shape, and may be any shape.

A valve unit 310 is installed at one end of the gas tank 300 in the longitudinal direction, and the valve unit 310 includes a pressure regulating valve, a fusible valve as a safety valve, and the like, and can be used to adjust the pressure of the hydrogen gas supplied to the fuel cell 200.

The number of the air tanks 300 may be one, two, or three or more. In the present embodiment, the number of the air tanks 300 is 4. The 4 air tanks 300 are fixedly stored in the air tank mounting frame 320, so that the air tanks are prevented from moving and colliding with each other. The air tank mounting frame 320 may be installed at a spatial position above the fuel cell 200 and between the top covers of the rear compartments. The air storage tank mounting frame 320 is fixedly connected with the vehicle body framework. In order to save space, the tank mounting frame 320 is provided in a two-layer structure, and two tanks can be fixed to each layer. The number of layers of the tank mounting frame 320 and the number of tanks per layer may be set according to actual conditions. Compared with the existing fuel cell passenger car structure with the air storage tank arranged on the roof, the layout structure can effectively reduce the overall height of the car body, improve the mobility of the car, such as the steering performance, and improve the aesthetic property of the car body.

Both the fuel cell 200 and the gas tank 300 are disposed in the rear compartment 130 of the passenger car body, and in the event of a leak in the gas tank, the hydrogen gas leaking from the gas tank flows rearward with the traveling wind, so that the leaked hydrogen gas can be prevented from entering the passenger car compartment and the cab in front.
