Dynamic and static simulation tool for PEM fuel cells

In the last decade, the interest in green power generators has increased. Hydrogen, especially, is a very promising fuel for generating electricity. Polymer electrolyte membrane (PEM) fuel cells are believed to play a leading role in the hydrogen economy, and therefore good simulation tools are needed. Lately, the focus of the research shifted from steady-state characteristics to dynamic behavior, due to the interest of electrical engineers in using PEM fuel cells. Until recently, there was na single model for simulating static and dynamic behavior of fuel cells. The models available do not incorporate both small- and large-signal behavior, and most of them use temperature measurements. This work presents´ a fuel cell model capable of simulating stead-state, small- and large-signal behavior in one model, implicitly covering temperature dependency without monitoring it
