Dynamic modelling and experimental analysis of PEMFCs: a comparative study

Abstract : Different Fuel Cell (FC) stacks or system models must be developed relevance to a specified main objective,either an accurate electro-chemical behavior descriptionoroptimization procedure at a system level. In this paper,the characteristics of cell polarization V-I curves arestudied for three different dynamicmodels (Dicks, impedance and electrical equivalent circuit). Thesimulation results, usingMATLAB-SimulinkTM,provideanadequateevaluation of each modelunder different load conditions.Although the different models provide acceptable results and are suitable for many applications particularlyembedded systems, the electrical equivalent circuit model offers accuracy four times better than the Dicks model.The experimental validation of the FC voltage-current characteristic obtained by the different models at steady-state and transient conditions is performed. The agreement between the simulation and the experimental results is adequate.
