Novel Designs for 7-Layer Membrane Electrode Assembly in PEM Fuel Cells: A Systematic Investigation of Mass Transport and Charge Transfer Processes in PEM Fuel Cells

This project gives design advice and a simulation framework for improving a 7‑layer membrane electrode assembly (MEA) used in proton exchange membrane (PEM) fuel cells for cars. The goal is to make the MEA thinner so that mass, electricity, and heat move more easily, while using less material. By looking at how the gas diffusion layer (GDL) works with the gas flow channels, the project studies the capillary‑pressure gradient needed to remove liquid water from the catalyst layer efficiently. With computational fluid dynamics (CFD) and numerical models, students can see how changes in GDL thickness, porosity, and flow‑channel shape affect reactant distribution and the cell’s polarization curve. The work also

includes mathematical models for multi‑phase transport, charge‑transfer kinetics, and water‑management inside the thin layers. In the end, the study helps weigh design trade‑offs to raise power density and fuel efficiency of PEM fuel cells, supporting greener automotive propulsion.
