Overview
abstract
The development of a parametric controller for the polymer electrolyte membrane (PEM) fuel cell system based on a dynamic model was studied. Dynamic modeling was carried out, focusing on obtaining the transient performance of the PEM fuel cell system. The parametric controller was then designed with the goal of tracking the output voltage and stack temperature set points by optimally manipulating the oxygen and hydrogen excess ratios, and cooling water flow rate based on a Model Predictive Control problem. The designed parametric controller can track the set points well, and ensures reliable performance in the presence of the current load fluctuations. It has the advantages of satisfying imposed constraints and can provide optimal inputs as explicit function of states of fuel cell stack. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA 2010 (Prague, Czech Republic 8/28/2010-9/1/2010).
