Black-box model and identification methodology for PEM fuel cell with overshooted transient response

One of the power sources with most potential is fuel cells, especially in on-board applications. The design of a power distribution architecture based on fuel cells for transport applications is a complex task, due to the number and nature of the power converters, loads, secondary energy sources, etc. Modeling and simulation are essential design tools at system level. This paper proposes a complete fuel cell black box model, in order to reproduce the behavior of a commercial fuel cell with overshooted transient response. The model is parameterized by applying an identification methodology based on manufacturer´s datasheets and a test based on load steps. The fuel cell black-box model is validated experimentally using a commercial PEM (Proton Exchange Membrane) fuel cell.
