  7. Abstract:
  8. In recent years, fuel cells have been proposed as an alternative option to conventional energy conversion systems. Fuel cell is an electrochemical system that can convert chemical energy to electrical energy without combustion. High efficiency, low temperature performance, poor pollution, good reliability, flexibility in the production potential, low start-up time and high life expectancy are the major advantages of this system. The most important barriers to the use of fuel cells are high cost polymer membrane and using expensive platinum catalysts. Modeling of fuel cells in general will meet two objectives. The first, due to the complexity of the processes taking place within the cell, these models can help spread awareness of researchers of various processes in the cell, and the second, the developed models can be useful tools for the design of fuel cells. This project is considered a PEM fuel cell. Volumetric flow rate of fuel and air as control variables and the partial pressure of hydrogen and oxygen are selected as controlled amounts. Proportional – integral controllers and feedback linearization method is used for system control. It is noteworthy that the simulation is done in MATLAB Simulink software
