In this dissertation, the effect of dynamic operation of a Ballard Nexa 1.2kw fuel cell system is investigated. Three specific topics are considered: the first is an analysis of the dynamic behavior of the fuel cell system, the second is an evaluation and examination of fuel cell membrane degradation during dynamic operation and the last is numerical simulation to predict the transient response in the cell voltage. To enable the analysis of the fuel cell system’s dynamic behavior, a simple method for analyzing the system’s voltage response to a step change in load resistance is presented. A modified Randles model is used as the system model, where two resistors and two capacitors are implemented for the Warburg impedance. Using that model, ...
