Fall 2014
An experimental set up based on a diffusion bridge is developed to accurately determine the in-plane and through-plane permeability, Knudsen diffusivity and effective molecular diffusivity of gas diffusion layers used in PEFC. The parameters are estimated under various compression levels in...

Fabrication and Testing of Inkjet Printed Electrodes for Anion Exchange Membrane Water Electrolysis
DownloadSpring 2022
To study the relatively novel technology of anion exchange membrane (AEM) water electrolysis in a scientific manner, a controllable and repeatable electrode fabrication method is needed. While inkjet printing has been successfully used to fabricate electrodes for proton exchange membrane (PEM)...

Geometric Tolerance Quantification and Prediction Framework for Additive Manufacturing Processes
DownloadFall 2021
Additive Manufacturing (AM) is an advanced manufacturing technology used to manufacture custom and geometrically complex parts using a layer-by-layer material addition process. Variations in the AM process lead to ‘deviations’ in the manufactured part, resulting in geometric non-conformance. To...

Improving Utilization of Ir-Based Catalyst Layers in Proton Exchange Membrane Water Electrolyzers
DownloadSpring 2024
In order to store large quantities of intermittent renewable energy, proton exchange membrane water electrolyzers (PEMWE) can be used to produce hydrogen which can then be used in a fuel cells to retrieve the energy. One limitation of PEMWE is that the catalysts used, commonly platinum and...

Fall 2011
Computer modeling is critical for catalyst layer (CL) design in polymer electrolyte membrane fuel cells. Water-filled and ionomer-filled agglomerate models have been suggested as representations of the CL microstructure. In this thesis, improved water-filled and ionomer-filled agglomerate models...

Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layers
DownloadFall 2014
Low catalyst content remains a key requirement for the commercialization of polymer electrolyte fuel cells (PEFCs) into the energy, transportation, and material handling sectors. Understanding the fundamental phenomena reducing fuel cell performance at various stages of operation play a major...

Fall 2024
Fossil fuel combustion results in carbon dioxide (CO${2}$) and particulate emissions which are linked to climate change and health problems, respectively. Hydrogen can be an alternative zero-emission fuel for future energy systems. However, hydrogen is not sufficiently available in nature in its...

Spring 2023
Flywheels are mechanical devices that store energy as the inertia of a rotating disk. Flywheel Energy Storage Systems (FESS) can combat the challenges of intermittency and unreliability that prevent effective integration of renewable energy sources into the electric grid. They have long...

Spring 2016
Heterogeneous materials are omnipresent in several critical engineering applications such as polymer electrolyte fuel cells (PEFCs), coal bio-conversion process, geological storage of CO2 and membrane water filtration. These applications rely on physical processes such as transport (e.g., mass,...

Fall 2021
Hydrogen fuel cells convert the chemical energy of hydrogen directly into electricity, with the only byproducts being heat and water. The high cost of hydrogen fuel cells due to the expensive platinum catalyst is one of the limiting factors to their global commercialization. Improving fuel-cell...
