Legacy Theses & Dissertations (2009 - 2024)
Several roadblocks prevent the large-scale commercialization of hydrogen fuel cells, including the stability of the Pt catalysts and their substrates, as well as the high cost of Pt. This is particularly true for the cathode, which requires a higher Pt loading because of the slow kinetics of the oxygen reduction reaction (ORR). The problem with the stability of the substrate can be solved by replacing the traditional carbon support with a conductive metal oxide such as reduced TiO2, which will not easily corrode and should result in longer lasting fuel cells. In this study, Pt was deposited either by atomic …
Development Of Integrated Tio₂ On Carburized Si Nanowires As A Catalyst/Support Structure For Alkaline Fuel Cells, Adam Lemke
Legacy Theses & Dissertations (2009 - 2024)
Due to a combination of environmental and economic motivations, there is a strong impetus to transition away from fossil fuels towards renewable sources of energy. Critical to achieving this goal will be technologies that allow for the storage and transmission of energy derived from renewable sources. Hydrogen fuel cells may play a significant role in making this a reality, allowing for the use of hydrogen as a non-carbon based fuel, in particular for vehicle applications. Hydrogen fuel cells directly convert chemical energy into electrical energy, with only water vapor and heat as waste products.
