Separation of mixed, grain and grain boundary conductivity in Gd-doped Ceria thin films and their response to sulfur poisoning

Andreas Nenning

TU Vienna, Christian Doppler Laboratory for Interfaces in Metal-Supported Electrochemical Energy Converters

Andreas Nenning is currently a postdoc in the Christian Doppler laboratory for metal stabilised SOFCs, in which he investigates the reaction mechanisms in Ni-Ceria SOFC anodes

Abstract

The in-plane conductivity of polycrystalline thin films depends on bulk and grain boundary conductivities. While both contributions may differ from bulk samples, it is difficult to separate them by impedance spectroscopic... [ view full abstract ]
