چکیده
Fig. 1: Power electronics system driving ac load, powered by a fuel cell. Abstract—A dynamic model of a PEM fuel cell is developed for power electronics simulation. The model accounts for static losses of activation, ohmic, and concentration regions, and dynamic transients due to charge double layer and compressor delay. In this paper, study was given to additional factors, including temperature, for their effects on the output voltage with respect to load on the fuel cell stack. Findings were analyzed and incorporated into the model based on testing with a Ballard Nexa 1.2 kW PEM fuel cell unit. The model is developed for PSPICE, then tested and compared to experimental data from the Ballard fuel cell system.
