Problems solved by technology

[0004] Therefore, in the traditional fuel cell test system, the discharge load needs to convert the electric energy generated by the fuel cell into heat energy for consumption, wasting a lot of energy
In addition, when the fuel cell is actually used, it will not be directly wasted after power generation, so the traditional fuel cell test system does not meet the actual use scenario of the fuel cell, and the test results cannot truly reflect the actual use conditions

Abstract

The novel fuel cell test system provided by the present invention includes a test bench, a hydrogen supply system and a cooling system, the hydrogen supply system is connected to the test bench, and the fuel cell is connected to the test bench through a dedicated pipeline; Battery pack and inverter; wherein, the output end of the fuel cell is connected to the input end of the DC / DC module, the output end of the DC / DC module is connected to the input end of the lithium battery pack, and the output end of the lithium battery pack is connected to the input end of the inverter The output terminal of the inverter is connected to the external equipment load. The electric energy generated during the fuel cell testing process of the system is stored in the lithium battery pack, and the external equipment load is supplied by the lithium battery pack, so that the electric energy generated by the fuel cell can be reused to save energy and improve energy utilization. In addition, since fuel cells are basically used in conjunction with lithium battery packs in actual use, the system can better simulate the actual use scenarios of fuel cells, and the test results are more realistic.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a novel fuel cell testing system. Background technique [0002] A fuel cell consists of multiple single cells, commonly known as a stack, which is the core component of the fuel cell power system assembly. The finished stack should be activated on the fuel cell test system first to activate the physical and chemical properties of the membrane electrodes, and after the assembly of the fuel cell power system assembly is completed, the performance test needs to be carried out on the fuel cell test system.
