Optimal fuel consumption in hydrogen fuel cell systems requires the maximum operation efficiency point (MEP) of the fuel cell to be found. The aim of this paper is to demonstrate the effectiveness of the “Perturb and observe” method during fuel cell operation through simulation. Those simulations use a fuel cell model based on data acquired on a fuel cell test bench. A maximum efficiency point tracking (MEPT) algorithm is used to track the current needed to reach the maximum efficiency. The method is simulated in a SIMULINK-MATLAB environment to verify the performance of the MEPT controller.
