Design and development of a 100 W Proton exchange membrane fuel cell uninterruptible power supply

Du Toit, Johannes Paulus (2006-01)

This study presents the design of a proton exchange membrane fuel cell stack that can be used to replace conventional sources of electrical energy in an uninterruptible power supply system, specifically for use in the ...
Design and development of a high performance zinc air fuel cell

Lourens, Dewald (2006-06)

The demand for efficient and environmentally friendly power sources has become a major topic around the world. This research explores the capability of the zinc-air fuel cell to replace conventional power sources for ...
Design and development of a remote monitoring system for fuel cells

Komweru, Laetitia (2006-07)

This dissertation presents the design and development of a remote monitoring system (RMS) for polymer electrolyte membrane fuel cells (PEMFC) to facilitate their efficient operation. The RMS consists of a data acquisition ...
Design and development of an off-grid e-learning centre for rural communities

Selaule, Vusimuze Edgar (2015-01)

The lack of electricity in off-grid rural communities in South Africa (SA) and Africa as well as the budget constraints on these communities restrict these communities from connecting to any online resources (internet and ...
Development of 3D inkjet printing heads for high viscosity fluids

Van Tonder, Petrus Jacobus Malan (2015-07)

Opening up local markets for worldwide competition has led to the fundamental change in the development of new products. In order for the manufacturers to stay globally competitive, they should be able to attain and ...
Evaluating the effects of radio-frequency treatment of rocks: textural changes and implications for rock comminution

Swart, Arthur James (2010-12)

Ore, from a mining operation, goes through a process that separates the valuable minerals from the gangue (waste material). This process usually involves crushing, milling, separation and extraction where the gangue is ...
Optimisation of the hydrogen pressure control in a regenerative proton exchange membrane fuel cell

Burger, Melanie (2012-10-24)

Industrial countries, such as South Africa, rely heavily on energy sources to function profitably in today’s economy. Based on the 2008 fossil fuel CO2 emissions South Africa was rated the 13th largest emitting country ...
Optimising the output power available from a photovoltaic panel through empirical testing

Osamede, Asowata (2013-09)

Einstein said, ‘‘the release of energy has not created a new problem, but has made more urgent the necessity of solving an existing one’’. This dissertation presents a method of optimising the available output power from ...
Solar driven hydrogen generation for a fuel cell power plant

Amoo, Akinlawon Olubukunmi (2012-11-01)

There are a number of ways to produce hydrogen using solar energy as the primary source. Water electrolysis, which uses solar electrical energy, is the rapidly available process. Hydrogen can be produced by using solar ...
