In this paper, a variable step size IC MPPT controller for the proton exchange membrane fuel cell (PEMFC) power system is proposed. The efficiency of the proposed algorithm has been studied successfully using a 7 kW PEMFC fed by DC‐DC boost converter derived using the proposed MPPT controller implemented under Matlab/Simulink environment. Comparison results obtained using both implemented fixed and variable step size IC MPPTs on two scenarios test considering temperature and hydrogen pressure variation show that the proposed variable step size IC MPPT outperforms the conventional fixed step size in static and dynamic performances.
