Vehicle-installed hydrogen supply system

Abstract

The invention provides a vehicle-installed hydrogen supply system. The vehicle-installed hydrogen supply system comprises a hydrogen supply pipeline and a hydrogen cylinder, wherein the hydrogen supply pipeline comprises an input end used for receiving hydrogen and an output end used for being connected with a fuel cell, the hydrogen cylinder is arranged between the input end and the output end ofthe hydrogen supply pipeline, the front end of the hydrogen cylinder communicates with the hydrogen supply pipeline through a connecting pipeline, a control valve set is arranged on the connecting pipeline to control the conveying amount of hydrogen, the rear end of the hydrogen cylinder is connected with the external environment, a release valve communicating with the hydrogen cylinder is arranged at the front end of the hydrogen cylinder, when the pressure in the hydrogen cylinder is higher than a pressure safety value, the hydrogen in the hydrogen cylinder is discharged through the releasevalve, a fusing valve is arranged at the rear end of the hydrogen cylinder, and when the temperature in the hydrogen cylinder is higher than a temperature safety value, the fusing valve is fused to discharge the hydrogen. The hydrogen cylinder in the vehicle-installed hydrogen supply system adopts two aspects of safety protection, and the safety of the hydrogen cylinder is better, so that the safe and reliable operation of the vehicle-installed hydrogen supply system can be ensured.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, and more particularly relates to a vehicle-mounted hydrogen supply system. Background technique [0002] With the country's strong support for the new energy vehicle industry, hydrogen-fueled battery vehicles have developed rapidly. Compared with internal combustion engine vehicles, this fuel cell vehicle not only has high energy conversion efficiency and long cruising range, but also achieves zero emissions, effectively It alleviates the environmental pollution problems caused by traditional fuel vehicles. [0003] The hydrogen supply system is an important part of the fuel cell vehicle, and the performance of the fuel cell vehicle depends more on the hydrogen supply system. In order to quickly occupy the market share of new energy, many companies have launched various hydrogen supply systems with uneven quality, which are not only cumbersome and redundant, but also have high manufac...
