Nikolaos Bonanos is a Materials Scientist with experience in the electrical and electro­chemical characterisation of materials. He has worked in university (Imperial College 1979-1984) and in industry (British Petroleum 1984-1992). Since 1993, has been at Risø National Laboratory for Sustainable Energy, now part of the Technical University of Denmark. He has participated in EU research programmes, including Joule II: New SOFC Materials and Techno­logy, Joule-Thermie: Improving the Durability of an SOFC Stack, INTAS: Hydrogen in Oxide Systems, MF‑SOFC: Scale up of a Multi-Functional Solid Oxide Fuel Cell (as project leader for Risø), and in a Programme called Advanced Ceramics for Protonics, sponsored by NEDO, Japan. Nikolaos Bonanos has co‑authored circa 50 scientific papers in international refereed journals.
His main research interests include materials development and electrode development for applications in solid oxide fuel cells, materials properties at high temperatures, transport number measurements, electrocatalysis, oxide-based proton conductors and their application to high temperature electrochemistry, modelling of electrical properties and structure-property correlations in polyphase systems, and technique development for materials characterisation, especially impedance spectroscopy.
