Abstract

The invention discloses a fuel cell system test bench and a test method, and belongs to the technical field of fuel cell systems. The fuel cell system test bench comprises a cell environment bin, an environment temperature regulation and control assembly, an air supply regulation and control assembly, an air pressure regulation and control assembly, a heat management assembly and a change-over switch, and the cell environment bin is used for accommodating a fuel cell system; the environment temperature regulation and control assembly is used for regulating and controlling the air temperature in the battery environment bin; the gas supply regulation and control assembly is used for conveying fuel gas with set air temperature and set air pressure to a gas inlet of the fuel cell system; the air pressure regulation and control assembly can enable the air pressure of air entering the fuel cell system to be smaller than standard atmospheric pressure and to be maintained at set atmospheric pressure; the heat management assembly is used for heating or cooling the fuel cell system; the change-over switch can selectively connect the fuel cell system with the electronic load or the power cell test unit. Plateau high-temperature and low-temperature test requirements can be met, and joint test of a fuel cell system and a power cell system can be met.

Description

technical field [0001] The invention relates to the technical field of fuel cell testing, in particular to a fuel cell system test bench and a testing method. Background technique [0002] Hydrogen fuel cell vehicles are one of the most widely used industries for hydrogen energy. The existing hydrogen fuel cell systems have the advantages of small size, large capacity, zero emissions, and no pollution. Hydrogen fuel cell vehicles and pure electric vehicles have a complementary relationship, and the development of hydrogen fuel cell vehicles is of far-reaching significance. [0003] Since hydrogen fuel needs to be stored or transported under low temperature or high pressure conditions, its storage capacity, stability and safety have become the most important constraints restricting the development of hydrogen fuel cell systems. The system test of the fuel cell system can help to quickly understand the performance of the fuel cell system, and understand the influence of the f...
