Abstract
Appropriate modelling and simulation system of Proton exchange membrane fuel cell is helpful to improving PEMFC design. In this paper, based on the electric field and temperature field of fuel cells, a mathematical model of a number of proton exchange membrane fuel cells is built, using the temperature and the electrochemical model. Through MATLAB simulation, the results show that the model better reflects the dynamic PEMFC system properties. The changes of operating temperature, gas pressure and membrane area, which affect the performance of the fuel cell output, were studied. At the same time, we designed a boost converter using PID control for proton exchange membrane fuel cell model, thus converting the fuel cell output voltage into stable supply 24 V for load.
