Title  Modeling method based on proton exchange membrane fuel cells on MATLAB
Abstract
Because proton exchange membrane fuel cells(PEMFC) has the high efficiency, pollution-free, lightweight device, low noise, fast start at room temperature and so on merit, and because of its high energy density and environmental protection, has become one of clean and efficient energy technologies in today's society the most promising,It is particularly suitable for use in mobile power, resulting in a high degree of attention around the world and widespread concern.

It is necessary to explore in depth study of the process of running for PEMFC and the influencing factors.Because of the complexity of  the system, PEMFC its own ,many of the key variables need to be taken into account. So based on theoretical modeling of PEMFC mechanism model approach is very difficult period of work.
In fact, in the actual power generation process, people in order to improve the reliability and stability of the PEMFC power system operation will be necessary with the possible control methods.This graduation project was first established empirical model of PEMFC electrochemical systems and dynamic model, and then the establishment of a control and simulation of temperature PEMFC system classical model and dynamic analysis of the model.The main work of this paper are:
l)I succinctly elaborated the PEMFC module working principle and main components of functionality and PEMFC management module.
2)According to the electrochemical fuel cell theory, I use MATLAB simulation tool SIMULLINK to establish a steady state model structure  PEMFC system, and analysising  the influence of temperature on the electrical properties of the stack.
3)This paper studies the dynamic behavior of the stack to generate electricity,  and mainly studied the influence of some parameters on the stack to run nonlinear resistance and dynamic output performance generated.I put the test results of the simulation are compared with experimental data to prove that the model is correct and feasible.
4)I use MATLAB in SIMULLINK components for PEMFC steady-state and dynamic models built two separate simulation and research.
