Iridium based mixed oxides as efficient anode catalysts for Solid Polymer Electrolyte (SPE) electrolysers
(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 ...
Platinum based catalysts for the cathode of proton exchange membrane fuel cells
(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 ...
Synthesis and characterization of cathode catalysts for use in direct methanol fuels cells
(University of the Western Cape, 2010)
In this work a modified polyol method was developed to synthesize in-house
catalysts. The method was modified for maximum delivery of product and proved to be quick and efficient as well as cost effective. The series of ...
Electrochemical responses of novel preferentially oriented platinum (100) nanoalloys for ammonia and hydrazine catalysis
(University of the Western Cape, 2013)
Ammonia has attracted attention as a possible fuel for direct fuel cells since it is easy to handle under low pressure, costs only slightly higher than methanol and can easily be cracked down into hydrogen and nitrogen. ...
