Dynamic characteristic study of proton exchange membrane fuel cell

In order to investigate the output characteristic of proton exchange membrane fuel cell (PEMFC) based on the electrical empirical, a novel dynamic model of PEMFC has been developed with Matlab/Simulink, which is distinct from the models have previously been published. By using a fuel cell test system in Fuel Cell Application Centre in Temasek Polytechnic, the transient electrical response of PEMFC was conducted and analyzed under various operating conditions. A good match is found between simulation results and experimental data. The comprehensive results of simulation manifested that the model is effective and operational. This model will be very useful to optimize the structure design, improve the operation performance, and develop the real-time control system of PEMFC.
