Polyacrylic acid and polyvinylpyrrolidone stabilised ternary nanoalloys of platinum group metals for the electrochemical production of hydrogen from ammonia
(University of the Western Cape, 2016)
The electrochemical oxidation of ammonia has attracted much attention as an efficient green method for application in direct ammonia fuel cells (DAFCs) and the production of high purity hydrogen. However, the insufficient ...
Electrochemical characterization of platinum based catalysts for fuel cell applications
(University of the Western Cape, 2012)
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR),
overpotential, and methanol fuel cross over ...
Synthesis, characterization and physicochemical properties of platinum naboparticles on ordered mesoporous carbon
(University of the Western Cape, 2011)
In this study SBA-15 mesoporous silica template was synthesized and used as a sacrificial template in the preparation of ordered mesoporous carbon material. A chemical vapour deposition (CVD) technique using LPG or ...
Synthesis and characterisation of proton conducting membranes for direct methanol fuel cell (DMFC) applications
(University of the Western Cape, 2005)
For a direct methanol fuel cell (DMFC), the proton exchange membrane must conduct protons and be a good methanol barrier. In addition to the high methanol permeability achieved by these membranes, they are very expensive ...
Synthesis of multi-metallic catalysts for fuel cell applications
(University of the Western Cape, 2008)
The direct methanol fuel cell or DMFC is emerging as a promising alternative energy source for many applications. Developed and developing countries, through research, are fast seeking a cheap and stable supply of energy ...
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 ...
Cesium hydrogen sulphate and cesium dihydrogen phosphate based solid composite electrolyte for fuel cell application
(University of the Western Cape, 2004)
A new high temperature solid electrolyte composite was developed, with CsHSO4 and CsH2PO4 as the proton conducting material in composition with PTFE and SiO2 to enhance the solid electrolyte composites mechanical strength ...
Polymer/nano-organic composite proton exchange membranes for direct methanol fuel cell application
(University of the Western Cape, 2005)
The proton exchange membrane is one key component of direct methanol fuel cells, which has double functions of conducting protons, separating fuels and oxidant. At present, the performance and price of sulfonic acid proton ...
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 ...
Characterization of platinum-group metal nanophase electrocatalysts employed in the direct methanol fuel cell and solid-polymer electrolyte electrolyser
(University of the Western Cape, 2005)
Characterization of nanophase electrocatalysts, which are an essential part in the direct methanol fuel cell (DMFC) and solid-polymer electrolyte (SPE) electrolyser, have been studied in this work. Their nanoparticulate ...
