[0002] Hydrogen energy is an important carrier for energy users to achieve green, low-carbon or even zero-carbon emissions. Currently, many countries around the world have designated green energy transformation plans and formulated medium- and long-term carbon emission targets. Therefore, hydrogen energy, as a green energy with zero carbon emissions, occupies an important position in the future energy system. The fuel cell system can directly convert the chemical energy of hydrogen into electrical energy without combustion. Fuel cells have the advantages of high energy conversion efficiency, zero pollution, and fast start-up.

Thirdly, when the degree of integration is high, it is difficult to replace the components under test, and the disassembly and assembly and arrangement of components consume a lot of time, and it is difficult to organize the test circuits of electrical components.
