Thus, PEMFCs are considered the first clean, efficient power generation device in the 21 st century. In recent years, fuel cell electric vehicles using a fuel cell stack module as a main power source have been actively developed in various countries around the world.

Among them, the Gas Diffusion Layer (GDL), the micro diffusion layer (MPL), and the Catalytic Layer (CL) have complicated microporosities. For a given structure, the microstructure greatly influences the transmission of substances in micropores under the condition of high current density, and simultaneously, the generated liquid water is easy to block the micropores, so that the substance transmission is deteriorated, and the external output power of the galvanic pile is reduced. Therefore, it is necessary to develop a novel fuel cell system and a control method of the fuel cell system, which can improve the microscopic material transfer of the fuel cell system and reduce the material transfer resistance and the occurrence of flooding for a given structure.
In summary, it is a problem to be solved urgently how to improve the material transmission of gas in the microstructure of the membrane electrode, timely open the blockage of pores in the microstructure caused by water production, and reduce the increase of material transmission resistance caused by flooding, thereby improving the working environment of the fuel cell and increasing the external output power.
