Embodiment 2

[0058] The present embodiment provides a durability test method. Through the implementation of the durability test system in the first embodiment, the durability test method is as follows:

[0059] The air in the sealed cavity is pumped into negative pressure through the exhaust assembly, the air pressure P in the sealed cavity is collected, and the air pressure P in the sealed cavity is compared with P0, where P0 is the standard atmospheric pressure, when P≥P0, the exhaust assembly Open, when P<P0, the exhaust assembly is closed. Specifically, before the durability test is performed on the hydrogen circulating pump 22 or the hydrogen injection valve 2, the air pressure value in the sealed chamber is first measured as P, and when the air pressure value P is greater than or equal to the standard atmospheric pressure P0, the third switch valve 15 is opened, And start the fan 14 to pump the airtight box 1, when the air pressure value P is less than the standard atmospheric pressu...

Embodiment 3

[0068] This embodiment also provides a vehicle, which relates to the technical field of fuel cells, and includes the above-mentioned durability testing system.

Abstract

The invention belongs to the technical field of fuel cells, and discloses a durability test system, a durability test method and a vehicle, the durability test system comprises a hydrogen supply assembly, a hydrogen circulating pump, a hydrogen injection valve, a booster pump, a first intercooler, a first switch valve, a second intercooler, a second switch valve, a heat dissipation assembly, a three-way valve and a box body, the box body is provided with the sealing cavity used for containing hydrogen, the hydrogen supply assembly is communicated with the sealing cavity, the hydrogen circulating pump and the hydrogen spraying valve are placed in the sealed box body filled with the hydrogen to be subjected to the durability test, and a large amount of hydrogen can be saved; according to the durability test system, durability tests of the hydrogen circulating pump and the hydrogen injection valve can be simultaneously considered by adjusting the first switch valve and the second switch valve, the test cost is reduced, and the durability test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a durability testing system, a durability testing method and a vehicle. Background technique [0002] With the development of the economy and the advancement of science and technology, low-carbon environmental protection has attracted more and more attention. The development of new energy vehicles has gradually shifted from electric vehicles to hydrogen fuel cell vehicles, devices that use hydrogen to generate electricity through chemical reaction with oxygen. Clean and pollution-free, with high specific power, it can meet the application requirements of transportation, stationary power supply and other fields. [0003] In the field of fuel cells, the hydrogen circulation pump and the hydrogen injection valve are the core components of the fuel cell, which transport the unreacted hydrogen from the outlet end of the fuel cell stack back to the inlet end of the stack for recycli...
