In this paper, a hybrid polymer fuel cell system with a lead-acid battery has been explored, so that the battery is designed to support the fuel cell system in providing the power needed for the load as well as storing additional energy. The battery is used to maintain the efficiency of the SOC battery. From a constant power strategy for a fuel cell and managing the fuel at the optimum operating point, to reducing the voltage load on the battery and reducing the instantaneous current load on the fuel cell in use. The general configuration of the hybrid system includes a polymer fuel cell followed by a boost converter, as well as a lead-acid battery pack, after which a bidirectional converter to control the power of the battery in charge and discharge mode. It's in the system. According to the simulation, it has been observed that the power contribution between the fuel cell and the battery is well suited to load changes, and the fuel cell always produces a constant power to charge the battery and power the load. It is protected from any kind of load fluctuation and interference.
