Dynamic modeling of a hybrid photovoltaic system with hydrogen/air PEM fuel cell

In this study, a photovoltaic-electrolyser-fuel cell system was considered and simulated. This hybrid system produces hydrogen in the daytime and stores it in the storage tank in order to supply the required energy for the peak period of demand. Dynamic behavior of the process components was analyzed under different conditions. Transient simulation represents performance of the components and the system, which the results can be used for improving the component’s efficiency and optimizing component’s size. The results obtained by this work, consist of hourly values of hydrogen produced by electrolyser unit, generated fuel cell energy to cover the energy demand, generated PV energy, dynamic behavior of the PEM fuel cell, tank pressure level, etc.
