Abstract: This paper aims at studying fuel cell energy production as a promising solution to replace fossil fuels. The management of the fuel cell stack (FCS) while connected to the grid is a real challenge due to FCS's high nonlinearity and the complexity of the power conditioning stage (PCS). Therefore, a nonlinear controller is designed to handle the energy between the FCS and the electrical grid. In fact, the FCS energy is supplied to the electrical grid through two stages (a high-gain DC-DC and DC-AC converters) and an LCL filter. The proposed controller is elaborated based on the backstepping approach, then a maximum power point tracking (MPPT) block and a fuel flow rate regulator are implemented to extract and exploit the maximum power. The suggested controller has been tested in MATLAB software, where the MPPT and the power factor correction are ensured.
