It begins by examining the environmental impact of fossil fuels and the promotion of renewable energies such as solar energy. The study then delves into the fundamental principles of hydrogen as an energy carrier and the operational concepts of fuel cells. Mathematical modeling and simulation techniques are employed to design and evaluate a hydrogen-powered fuel cell system. These models are used to optimize system performance and guide further development. Finally, the thesis addresses the practical implementation by constructing a prototype, which serves to assess the efficiency and viability of hydrogen as a clean energy source for electricity generation and the total cost of the proposed system.enHydrogen energy, Fuel cell (PEMFC), Renewable energy, Solar energy,Photovoltaic system (PV) ,Electrolysis, Hydrogen storage, MPPT (Maximum Power Point Tracking), Boost converter, PEM electrolyzer, Simulation , MATLAB/Simulink, Inverter ,Green hydrogen , Energy transition, Sustainable energy, Prototype, Techno-economic analysis.Thesis
