Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0028] like figure 1 As shown, a vehicle fuel cell system of the present invention includes an air compressor 1, an air storage tank 2, an air pressure reducing valve 3, an air regulating valve 4, an air flow meter 5, a data receiver 6, a fuel cell 10, Hydrogen flow meter 11, hydrogen regulating valve 12, hydrogen pressure reducing valve 13, hydrogen tank 14, integrated controller 15 and detection device.
[0029] The air compressor 1 is connected to the air storage tank 2 to provide high-pressure air for the air storage tank 2 . The power density of the vehicle fuel cell increases with the increase of the oxygen pressure, so the present invention uses an air compressor to increase the air supply pressure, thereby increasing the oxygen pressure in the air.
[0030] The air storage tank 2 is connected with the high-pressure air inlet of the air pressure reducing valv...

Description
technical field [0001] The invention relates to a vehicle fuel cell system and a working method thereof. Background technique [0002] At present, the requirements for energy saving and emission reduction are becoming increasingly stringent, energy saving and environmental protection have become research hotspots, and vehicle fuel cell technology has also become the focus of research. [0003] Compared with traditional internal combustion engine vehicles, fuel cells use hydrogen as fuel. Vehicle fuel cells do not go through the heat engine process and are not limited by the Carnot cycle. They have the incomparable advantages of internal combustion engine vehicles such as high energy conversion efficiency and environmental friendliness. Maintain the high speed, long-distance driving, safety and comfort performance of traditional internal combustion engine vehicles. Vehicles using fuel cells are considered to be the preferred clean and efficient means of transportation in the...
