Short life span and low efficiency is a general issue of fuel cell systems. Therefore, designing and simulating a system capable of measuring crucial parameters of a PEMFC is essential for achieving an improved system performance. A polarization curve is utilized to evaluate the performance of a fuel cell, so this paper is focused on a variety of critical parameters and their output is traced specifically on a polarization curve. The system design was simulated in Matlab-Simulink and the data agreed well with the published data. The output of this study has the potential to contribute in renewable energy sectors, and industry.enProton exchange membrane fuel cell (PEMFC)Fuel cell systemsEfficiencyDissertation, Academic -- South Africa.Proton exchange membrane fuel cells.Thesis
