Development of a Mathematical Model for Proton Exchange Membrane Fuel Cells (PEMFCs)

This paper presents the development and validation of a mathematical model for Proton Exchange Membrane Fuel Cells (PEMFCs). The approach developed herein uses both static and dynamic modeling to represent PEMFC performance under different conditions. These include variations in load current, gas pressure, and temperature. The model was built in MATLAB and tested with experimental data from the BAHIA test bench. The results confirm its accuracy in both steady and changing states. The model was also compared with other approaches, such as the MATLAB PEMFC model and the Energetic Macroscopic Representation (EMR) framework. Findings show that the model can predict important electrochemical and physical processes with precision. It also gives useful insights into PEMFC performance and optimization. This work presents a reliable future basis for advanced PEMFC performance studies and emulator development.
