Abstract
A 50kW class PEMFC and 30kAh battery was evaluated to find a correlation between the stack net power overshoot and the stack temperature for sudden load change. First, a 50kW class PEMFC (Proton Exchange Membrane Fuel Cell) model and a battery model were designed and verified using experimental values. Sensitivity study of Energy Management system strategy was also carried out to find the optimal power ratio of the stack and the battery. Next, net power overshoot of the stack and the temperature data of the stack during a sudden load change were compared. The results show that the main factors affecting the Energy Management System strategy of the stack is the stack temperature.
