Numerical Simulation based Modeling and Analysis of Fuel Cell System

Fuel cells are considered as the potential for future clean energy in both electrical energy transmission and mobile applications. The biggest challenge in the operating fuel cell system is how to obtain the highest efficiency of fuel cell output voltage in the presence of many variables that affect the work of the cell such as the fuel pressure, temperature, humidity, load current as well as the non-linear dynamical behavior for fuel cell system. This paper presents the modeling of fuel cell system based on the nonlinear mathematical model and analysis it. In this work, it analyzed and studied the stability and the dynamic behavior response of fuel cell output voltage model by using MATLAB/m. files simulation to illustrate the effectiveness performance of the fuel cell system when changing the hydrogen partial pressure and temperature variation of the fuel cell as well as the characteristic of the fuel cell voltage against load current variation.
