This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.
Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

A MIXED WETTABILITY PORE SIZE DISTRIBUTION MODEL FOR THE ANALYSIS OF WATER TRANSPORT IN PEMFC MATERIALS
DownloadFall 2013
Mateo Villanueva, Pedro Abdiel
Water management on proton exchange membrane fuel cells is one of the biggest issues that stop the effective commercialization of this promising technology. Due to water flooding, the performance of fuel cells decays rapidly at high current densities. To better design fuel cell electrodes, a...

Fall 2016
Polymer electrolyte fuel cells (PEFCs) operate with a ternary mixture of fuel and reactants. The majority of numerical models in the literature, including the in-house Open-source Fuel Cell Simulation Toolbox (OpenFCST) software, use Fick’s law of diffusion which is only valid for binary...

An Oxygen Reduction Reaction Kinetic Model for Proton Exchange Membrane Fuel Cells Based on Free Energies of Activation and Adsorption
DownloadSpring 2023
Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative technology to internal combustion engines used on vehicles. However, improvements on durability and performance are needed in order to boost the commercialization of this technology. The oxygen reduction reaction (ORR)...

Analysis of an Open-Cathode Fuel Cell Stack in an Enclosure for Varying Operating Conditions
DownloadSpring 2013
Open-cathode polymer electrolyte fuel cell (PEFC) stacks use hydrogen as a fuel, are a high efficiency power source, and do not produce CO2, NOx, SOx, or particulate matter. When used as a remote power source, the PEFC stack must be protected from adverse environmental conditions. To provide...

Analyzing Multiphase Flow in Membrane Electrode Assembly Using a Mixed Wettability Mathematical Model
DownloadFall 2018
Improving fuel cell performance at high current density is critical for reducing stack size, cost and weight in automobile applications. A major source of performance losses at high current density is the accumulation of liquid water in the electrode which blocks reactant transport. Studying...

Characterization of Water Transport and Liquid Accumulation in Proton Exchange Membrane Fuel Cells
DownloadSpring 2024
Hydrogen proton exchange membrane fuel cell (PEMFC) vehicles present a viable solution for decarbonizing the heavy-duty and long-distance transportation sector. They convert the chemical energy of hydrogen directly into electricity, with the only by-products being heat and water and, therefore,...

Estimation of relative transport properties of fuel cell and electrolyzer transport layers by pore network and continuum based direct simulations
DownloadSpring 2020
Improvements in the imaging techniques have enabled the capturing of images with high resolution, thereby permitting the reconstruction of complex porous media that can be analyzed by computer simulations. The two most popular methods for numerically analyzing transport in porous media are pore...

Fall 2016
The success of commercial applicability of polymer electrolyte fuel cells (PEFCs) depends on the cost competitiveness with respect to current energy sources. A major fraction of the system cost can be mitigated by reducing the amount of platinum (Pt) catalyst in the electrodes and by improving...

Fall 2018
Understanding the movement of water within a polymer electrolyte membrane (PEM) fuel cell is critical for improving performance at high loads. In this work, an experimental setup was designed and assembled for monitoring the in situ distribution of water contained within the anode and cathode of...

Experimental and Theoretical Investigation of Solar Molten Media Methane Cracking for Hydrogen Production
DownloadFall 2014
Canada is the largest H2 consumer per capita in the world, giving a strong market demand for H2. H2 is commercially produced using steam CH4 reforming, which is energy and CO2 intensive. Solar molten metal CH4 cracking is an alternative zero emissions technology. Solar radiation is focused with...
