Modeling and simulation of hybrid system coupling a photovoltaic generator, a PEM fuel cell and an electrolyzer (Part II)

This paper focuses on the integration of a photovoltaic generator (GPV), a PEM fuel cell (PEMFC), an electrolyzer and a hydrogen storage tank for sustained power generation. In the proposed PV-FC hybrid system, the PV generator feeds a variable load through a DC-DC converter controlled by an MPPT control (maximum power point tracking) and transfers energy to the electrolyzer side if possible to produce hydrogen which will be stored in a tank for a later use in the fuel cell (PEMFC). When the PV system cannot completely meet the load demands, the FC system provides the lack of power. The MATLAB-Simulink environment is used for the simulation of the PV-FC hybrid proposed system. Simulation results are presented in order to highlight the performances of proposed hybrid system.
