In this thesis study, a PEM fuel cell was modeled. Using the model, the most important performance parameters of the PEM fuel cell, namely operation temperature and pressure were investigated and their affects were determined on the PEM fuel cell performance. The performance is reflected primarily in the PEM fuel cell output voltage, electrical power output and efficiencies. The basic results of the PEM fuel cell modeling (Table VII. 1) are presented below
