Structural and Transportation Properties of Strontium Titanate Composites with Ion Conductive Oxides
Journal Title: Acta Energetica - Year 2016, Vol 27, Issue 2
Abstract
This paper has been written based on the author’s doctoral dissertation “Structural and transportation properties of strontium and titanate composites with ion conductive oxides”, prepared under the supervision of Prof. Dr. Hab. Eng. Bogusław Kusz at the Department of Solid State Physics of Gdańsk University of Technology. It reports the idea of the thesis and conclusions from the study. Niobium doped strontium titanate (Sr(Ti,Nb)O3) composites with selected ion conductive oxides (yttrium oxide-stabilized zirconium oxide YSZ and cerium oxide CeO2) were developed for the dissertation and their properties examined.. It was shown that Sr(Ti,Nb)O3-YSZ composite as the anode in an oxide fuel cell leads to its improved performance compared to a cell with a single-phase Sr(Ti,Nb)O3 anode. Microscopic observation confirmed that Sr(Ti,Nb)O3-YSZ composite as the functional layer between a Sr(Ti,Nb)O3 anode and YSZ electrolyte mitigates the problem of the composite anode’s delamination from the electrolyte surface. It was also shown that an appropriate modification of the Sr(Ti,Nb)O3-YSZ composite anode surface structure by infusing the process of hydrogen’s electrochemical oxidation with a catalyst (e.g. with nickel) can lead to further improvement of the fuel cell performance.
