Advanced Dynamic Control Approaches for the Fuel Cell System Based on Flow Rate

The performance of the fuel cell electric vehicle is better than that of the IC engine. Fuel cell-powered electric vehicles present an intriguing option due to their increased efficiency and clean energy source. Fuel cells (FC) give off electricity to the load continuously, hence the fuel cell system needs control strategies. This paper presents two control strategies to establish Maximum Power Point Tracking (MPPT) through flow rate controls for fuel cell. The first control approach is applied to manage the flow rate of fuel and enhance the fuel cell power. The methodology focuses on maximizing a fuel cell's power output by dynamically modifying the reactant flow rate based on actual operating conditions. Further, it also maintains the boost converter’s consistent output voltage which is connected to the fuel cell for boosting the voltage with another technique. This technique is appropriate for enhancing the fuel cell performance. The simulation results indicate that the suggested MPPT approach successfully optimizes power production and enhances the fuel cell system's overall efficiency. The control technique's performance is evaluated through MATLAB simulation.
