Modeling and simulation of PEM fuel cells based on electrochemical model

At first, the cell structure and the operating principle of proton exchange membrane fuel cell (PEMFC) were introduced, the electrochemical modeling of PEMFC was analyzed particularly. Based on the electrochemical model, A simulation model has been developed with Matlab/Simulink. With the help of this simulation model, a series of analyses are carried out. There is an excellent agreement between the simulation results and experiments. This simulation model also adapted to the simulation of PEMFC stack. This model is capable of characterizing the transient dynamic properties of a fuel cell system, and can be readily employed in the optimization of PEMFCs installed in the practical automotive or stationary applications.
