Abstract
The Maximal Power Point Tracking (MPPT) is a method employed to maximize the generated power from an energy
source, such as PV (photovoltaic) or PEMFC (Proton Exchange Membrane Fuel Cell). In this study, the Grey Wolf
Optimizer algorithm is utilized for the MPPT to regulate the boost converter positioned between the stack cell and the
battery. The primary challenge addressed by the MPPT is that the efficiency of PEMFC is influenced by the supplied
gases and cell temperature. To maintain optimal performance, the system aims to operate at the efficient power point,
and the MPPT assists in achieving this by adjusting the voltage to align with the point where the PEMFC characteristic
yields the maximum available power. Consequently, the MPPT’s objective is to identify the Maximum Power Point (MPP)
and guide the PEMFC to operate at this specific point. This process is essential to overcome challenges associated with
fluctuating inputs and to optimize the system for improved performance in a PEMFC. Typically, the MPPT control
algorithm involves modifying the converter duty cycle (denoted as D) to compel the PEMFCs to operate at their MPP,
ensuring efficient power production even under varying input conditions
