The rapid growth of Electric Vehicles (EVs) has spurred a surge in energy demand, emphasizing the imperative need for renewable energy sources. One such energy source that can be integrated into EVs to meet their charging requirements is the fuel cell (FC). However, the integration of FCs with EVs necessitates the use of power electronics converters. These converters play a vital role in matching the load voltage, as the FC output voltage tends to decrease under higher load demand. To enhance the performance of FCs and their integration with batteries, this study introduces a novel state-flow control mechanism. The primary goal of this research is to address the challenges posed by decreasing FC output voltage in response to higher load demands. To evaluate the proposed solution, a hybrid input source is supplied under three different load conditions: low, medium, and high. Extensive validation is conducted, with simulation results obtained through MATLAB Simulink. Additionally, an experimental setup has been established in LABVIEW, tailored specifically for fuel cell operations. The findings of this study encompass a detailed analysis of voltage, current, and efficiency under all three load conditions. These results provide valuable insights into the effectiveness of the proposed state-flow control mechanism in optimizing the performance of both FCs and batteries, making them well-suited to meet the escalating energy demands of Electric Vehicles.
