Problems solved by technology

In the hybrid power system, the fuel cell is used as the main power source, and the lithium-ion battery pack is used as the auxiliary power source. This type of power system prolongs the service life of the fuel cell to a certain extent through its complex intelligent hybrid power management system, but because it does not Isolating the energy output of the fuel cell from the power demand of the load, the contradiction between the reactivity and stability of the fuel cell has not been completely resolved
