Development of membrane electrode assemblies based on electrophoretic deposition for high temperature polymer electrolyte membrane fuel cell applications
Felix, Cecil (2013)High Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) have received renewed interest in recent years due to its inherent advantages associated with the limitations faced by Low Temperature Polymer Electrolyte ... -
The effect of flow field design on the degradation mechanisms and long term stability of HT-PEM fuel cell
Bandlamudi, Vamsikrishna (University of the Western Cape, 2018)Fuel cells are long term solution for global energy needs. In current fuel cell technologies, Proton Exchange Membrane (PEM) fuel cells are known for quick start-up and ease of operation compared to other types of fuel ... -
Effect of synthetic methods on the characteristics and performance of IrO2 catalysts
Karels, Simoné (University of the Western Cape, 2022)For many years fossil fuel has been the primary source of energy worldwide though, the environment is negatively affected because of the high carbon dioxide (CO2) emissions associated with the use of fossil fuels. Hydrogen ... -
Factors influencing fuel cell life and a method of assessment for state of health
Dyantyi, Noluntu (University of the Western Cape, 2018)Proton exchange membrane fuel cells (PEMFC) converts chemical energy from the electrochemical reaction of oxygen and hydrogen into electrical while emitting heat, oxygen depleted air (ODA) and water as by-products. The ... -
Gas diffusion electrodes for high temperature polymer electrolyte membrane fuel cells membrane electrode assemblies
Barron, Olivia (University of the Western Cape, 2014)The need for simplified polymer electrolyte membrane fuel cell (PEMFCs) systems, which do not require extensive fuel processing, has led to increased study in the field of high temperature polymer electrolyte membrane fuel ... -
Iridium based mixed oxides as efficient anode catalysts for Solid Polymer Electrolyte (SPE) electrolysers
Felix, Cecil (2010)The objective of the thesis is to develop highly efficient catalysts for solid polymer electrolyte (SPE) electrolyser anodes.The anode is the primary cause of the large overpotential of SPE electrolysers and also adds ... -
A modified Adams fusion method for the synthesis of binary metal oxide catalysts for the oxygen evolution reaction
Soudens, Franschke A (University of Western Cape, 2020)The majority of the global energy is sourced from conventional fossil fuels. The high demand for energy is accelerating along with the depletion of these fossil fuels. Hence, the shift to renewable energy sources and ... -
Platinum based catalysts for the cathode of proton exchange membrane fuel cells
Ndzuzo, Linathi (University of the Western Cape, 2018)Oxygen reduction reaction (ORR) is carried out in the cathode of the proton exchange membrane fuel cell (PEMFC) and it is known for its sluggish kinetics and the existence of two-pathway mechanism, related with the production ...
