Modeling and simulation of PEM fuel cell with bond graph and 20sim

Due to the increasing and highly promising use of fuel cells as an important electrical energy source, its modeling has been a major research issue for some years, trying to find mathematical models precise enough to accurately predict how a cell will behave in a real world system, without becoming too complex. Many attempts have been made using different techniques. In this paper, the authors describe a static model for the PEM (proton exchange membrane) fuel cell, developed by means of bond graphs and simulated in 20 sim. The model proves to be simple and accurate, reproducing the characteristic curve of a commercial PEM fuel cell.
