Abstract

The invention discloses a test system for a hydrogen injector of a fuel cell. The test system comprises a gas supply module, an electric pile simulator, an acquisition module and a central control module, the gas supply module comprises a pressure reducing valve used for being communicated with a gas source and a gas inlet electromagnetic valve communicated with the pressure reducing valve, and agas outlet of the gas inlet electromagnetic valve can be communicated with a gas inlet of a tested ejector; an air inlet of the galvanic pile simulator can be communicated with an air outlet of the tested ejector; the acquisition module comprises a first pressure sensor positioned at an air inlet of the stack simulator and a second pressure sensor positioned at an air outlet of the stack simulator; the central control module is used for being electrically connected with the air inlet electromagnetic valve, the tested ejector and the collection module. According to the invention, the phenomenonof damage to the galvanic pile during testing can be avoided.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a test system for a fuel cell hydrogen injector. Background technique [0002] Fuel cell is a high-efficiency power generation device, which has the advantages of high power density, high energy conversion efficiency and quiet working process, and has been successfully applied in the automotive field. When the fuel cell is in operation, it is necessary to feed hydrogen to the anode of the fuel cell and oxygen to the cathode respectively. The existing method of feeding hydrogen to the anode of the fuel cell is generally to control the pressure and flow of hydrogen input into the fuel cell through an injector. [0003] Existing injectors need parameter calibration and matching debugging before use, and the existing calibration method is generally to directly place the injector in the entire fuel cell system for testing. However, such a test method may cause damage to t...
