Solid oxide fuel cells are highly efficient energy conversion devices made with advanced ceramic materials. They can be used in different ways to produce electrical power, heat and useful chemicals, or to dispose of harmful greenhouse gases and air pollutants. My research investigates the application of solid oxide fuel cell (SOFC) technology to the utilisation and disposal of renewable and waste gas feedstocks. More generally, the aim of my research is to demonstrate the technical benefits and versatility of fuel cell technologies and why they are key to future energy infrastructures alongside other energy technologies.
