Model Comparison and Parameter Estimation of Polymer Exchange Membrane (PEM) Fuel Cell Based on Nonlinear Least Squares Method

The comparison of different single cell PEMFC models and the estimation of model parameters are described in this article. Three different models are selected from literature and reviewed. For each PEMFC model the polarization curves were developed and then compared. Nonlinear Least Squares Method have been implemented to find the parameters of each model. The results show that some of the parameters estimated are in agreement with the experimental and simulation model polarization curves while there are more errors in the estimation of the parameters describing the activation losses.
