Multilayer composite nylon hydrogen supply pipeline assembly and fuel cell electric vehicle comprising same

Abstract

The invention discloses a multilayer composite nylon hydrogen supply pipeline assembly and a fuel cell electric vehicle comprising the same. The multilayer composite nylon hydrogen supply pipeline assembly comprises a pressure reducing valve connecting joint used for connecting a pressure reducing valve, a fuel cell stack connecting joint used for connecting a fuel cell stack, a manual discharge valve and two multilayer composite nylon pipes. Two ends of one multilayer composite nylon pipe are respectively connected to the pressure reducing valve connecting joint and one end of the manual discharge valve, and two ends of the other multilayer composite nylon pipe are respectively connected to the other end of the manual discharge valve and the fuel cell stack connecting joint. The pressure reducing valve connecting joint, the fuel cell stack connecting joint and the manual discharge valve are communicated with the two multilayer composite nylon pipes. The multilayer composite nylon hydrogen supply pipeline assembly is light in overall weight, compressed hydrogen is conveyed safely and effectively, and the endurance mileage of the whole vehicle is high. Meanwhile, the advantages of high production efficiency and low cost are achieved.

Description

technical field [0001] The invention relates to a multilayer composite nylon hydrogen supply pipeline assembly and a fuel cell electric vehicle comprising the same. Background technique [0002] In new energy fuel cell vehicles, a hydrogen supply system is required between the new energy fuel cell vehicle pressure reducing valve and the stack to deliver compressed hydrogen fuel with a gauge pressure lower than 3000Kpa. The traditional hydrogen supply system generally uses metal hydrogen supply pipelines to transport, but as the market has higher and higher requirements for the mileage and safety of new energy fuel cell vehicles, the traditional hydrogen supply system is heavy, costly, and low in production efficiency. , The shortcoming of complex process is also gradually exposed. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art. The present invention provides a multi-layer co...
