Exploration of Novel Fuel Cell Materials
Fuel cells convert chemical energy directly into electrical energy with high efficiency and low emission of pollutants. In a fuel cell the reaction between hydrogen and oxygen produces water and electricity and as such provides a clean alternative to fossil fuels. The solid oxide fuel cell (SOFC) is highly efficient, stable, and operates over a wide temperature range (650 – 800°C). Applications include auxiliary power units in cars and heat engine energy recovery devices. In order to reduce system costs it is highly desirable to find new materials which exhibit significant ionic conductivity at lower temperatures (< 650°C).
The project will focus on the synthesis of novel transition metal oxides containing molybdenum or tungsten which exhibit high oxide ion conductivity at low temperatures (< 650°C). The materials will be synthesised via conventional solid state chemistry techniques and analysed by powder X-ray and neutron diffraction, AC impedance, and thermogravimetric analysis.
There will also be the opportunity to attend conferences and training courses.
The successful candidate should have, or expect to have, an Honours Degree at 2.1 or above (or equivalent) in Chemistry or cognate discipline.
Essential Background of Student: Knowledge of solid state synthesis and X-ray diffraction would be highly desirable, but not essential.
Knowledge of: Transition metal chemistry, electronic properties.
There is no funding attached to this project, it is for self-funded students only
