Advanced materials on the basis of nanostructured catalysed magnesium hydride for hydrogen storage
Goh, Jonathan Teik Ean (University of the Western Cape, 2019)Magnesium hydride has long been regarded as a promising candidate for lightweight hydrogen storage applications, owing to reasonably high theoretical capacity (7.6 wt. %). It is burdened by slow absorption/desorption ... -
Advanced oxygen reduction reaction catalysts/material for direct methanol fuel cell (dmfc) application
Motsoeneng, Rapelang Gloria (University of the Western Cape, 2014)Fuel cells are widely considered to be efficient and non-polluting power source offering much higher energy density. This study is aimed at developing oxygen reduction reactions (ORR) catalysts with reduced platinum (Pt) ... -
Characterization of platinum-group metal nanophase electrocatalysts employed in the direct methanol fuel cell and solid-polymer electrolyte electrolyser
Williams, Mario (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 ... -
Electrochemical Characterization of Platinum based anode catalysts for Polymer Exchange Membrane Fuel Cell
Gcilitshana, Oko Unathi (University of the Western Cape, 2008)In this study, the main objective was to investigate the tolerance of platinum based binary anode catalysts for CO poisoning from 10ppm up to1000ppm and to identify the best anode catalysts for PEMFCs that tolerates the ... -
Electrochemical energy conversion using metal hydrides hydrogen storage materials
Jonas, Ncumisa Prudence (University of the Western Cape, 2010)Metal hydrides hydrogen storage materials have the ability to reversibly absorb and release large amounts of hydrogen at low temperature and pressure. In this study, metal hydride materials employed as negative electrodes ... -
Electrochemical investigation of platinum nanoparticles supported on carbon nanotubes as cathode electrocatalysts for direct methanol fuel cell
Ntlauzana, Asanda (University of the Western Cape, 2010)The particles of the Pt metal were well dispersed on carbon nanotubes when EG was used and in isopropanol poor dispersion was observed and no further investigation was done on them. The platinum wt% on the supports observed ... -
Electrochemical study of electrode support material for direct methanol fuel cell applications
Bangisa, Andisiwe (University of Western Cape, 2013)This study focused on binary PtRu and PtSn electrocatalyst, synthesized using the polyol approach and supported on MWCNTs, TiO2 and MoO2 materials, after synthesis part of the resultant electrocatalyst was heat treated ...
