  7. Abstract:
  8. Focusing on fossil fuel to secure energy demand lead to big challenges. Hydrogen as alternative for fossil fuel has attracted a lot of attentions. Fuel cell with an electrochemical reaction which it’s byproducts are water and heat convert Hydrogen into electricity. High efficiency and low environmental pollution, persuade many researchers toward fuel cell commercialization. But problems such as high cost, high power oscillation and inertia, avoid fuel cell from significant development. One way to deal with these problems is using the fuel cell and battery hybrid system. In recent decade too many research has been made in utilizing this hybrid system in transportation. This project has been studied the application of fuel cell and battery hybrid system to provide residential electrical demand. Firs the typical scheme of the system was considered. The formulas of each part of system were driven and model was simulated in MATLAB software. Simulation results allow verifying suitable sizing of the components and the control strategy of the energy management system. By considering simulation results comprehensive structure of system was generated. After system integration it was time to test. With no increase in volume and a slight increase in mass compared to the fuel cell alone, this hybrid power source offered many benefits such as limiting the fuel cell power, increasing the system peak power, improving response to the load
