Towards greener fuel cells
The doctoral dissertation of MSc (Tech) Harri Ali-Löytty examines ferritic stainless steels. They have recently attracted widespread scientific interest due to their excellent corrosion resistance, mechanical strength and affordability.These properties make ferritic stainless steels an attractive choice for a broad range of energy applications.
The corrosion resistance results from the protective oxide layer that forms spontaneously under oxidizing conditions. At elevated temperatures, oxidation resistance can be enhanced by controlled surface treatments or by microalloying with elements that affect the formation of the oxide layer through segregation and interfacial oxidation.
Ali-Löytty’s research results can be applied to designing ferritic stainless steel alloys and surface treatments that facilitate the formation of the protective oxide layer with the optimum composition under various demanding application conditions, especially in solid-oxide fuel cells.
Public defence of a doctoral dissertation on Tuesday, 19 February
The doctoral dissertation of MSc (Tech) Harri Ali-Löytty in the field of physics titled “Microalloying Mediated Segregation and Interfacial Oxidation of FeCr Alloys for Solid-Oxide Fuel Cell Applications” will be publicly examined at the Faculty of Natural Sciences of Tampere University of Technology (TUT) in room K1702 in the Konetalo building (address: Korkeakoulunkatu 6, Tampere, Finland) at 12:00 on Tuesday, 19 February 2013.
The opponent will be Professor Anders Nilsson (Stanford University, California, USA). Professor Mika Valden from the Optoelectronics Research Centre at TUT will act as Chairman.
Harri Ali-Löytty (28) comes from Tampere, Finland, and works as a researcher at the Optoelectronics Research Centre of TUT.
