Thesis Title: Transport Phenomena in Cathode Catalyst Layer of PEM Fuel Cells

About

I hold B.Sc. (with honors) and M.Sc. degrees from Bangladesh University of Engineering & Technology, and a second M.Sc. degree from the University of Alberta. Next, I earned my Ph.D. in Mechanical Engineering from the University of Waterloo under the guidance of Prof. Xianguo Li.

My Ph.D. dissertation work focused on the fundamental investigation and transport modeling of polymer-electrolyte fuel cells (PEFCs). Since the thicknesses of various layers in PEFCs are about few micrometers to few millimeters to a micron, it is extremely difficult to study transport phenomena inside the PEFCs experimentally. Numerical models are the only means to gather insight on the physical phenomena occurring inside the PEFCs. I have developed mathematical model using volume-averaging technique and have investigated transport phenomena using finite element simulations. I have also developed models for activation polarization, effective transport properties, and liquid-water saturation inside the PEFCs. These models provide a route towards identification and eventual optimization of controlling phenomena and, consequently, will allow developing more accurate models and improved designs of PEFCs.

I have authored over 19 peer-reviewed articles on fuel cells, micro-fluidics, colloidal interactions, and convection heat transfer, and have presented my work at various international and national meetings. I have also been the recipient of a number of prestigious awards, including the Alexander Graham Bell Canada Graduate Scholarship.
