Fast oxide-ion and proton conductors are the subject of considerable research due to their technological applications in sensors, ceramic membranes and solid oxide fuel cells (SOFCs). This thesis describes the use of computer modelling techniques to study point defects, dopants …
The purpose of this thesis was to carry out the experimental study of direct ammonia fuel cells. The use of hydrogen in fuel cells poses a lot of problems. There is a lot of safety, technical and economic issues to be overcome to make its use as a fuel widespread. Ammonia is bei…
The demand for electric power has been steadily increasing, and this trend is expected to continue over the coming decades. With the increased usage of fossil fuels, there has been a growing concern with the environmental impacts of electric power generation. Therefore, penetrat…
