PEM fuel cell dynamic model for electronic circuit simulator

This paper presents a PEM fuel cell dynamic modeling, to be employed with electronic circuit simulator software - PSIM. Simulations of the proposed model for the fuel-cell, supplying a step-up DC-DC converter are presented. Comparisons with existing models are also made. Practical results are presented in this paper for a Ballard 1.2kW Nexa Power Module for theoretical-experimental comparisons.
