The enhancement of electroactivity and stability of solid oxide fuel cell (SOFC) cathodes is an open issue for the scientific community. Only a careful experimental approach, coupled with advanced modelling and interpretation, allows for a comprehensive understanding and optimization of materials not completely exploited, such as...

The suitability of impedance measurements in Solid Oxide Fuel Cells (SOFCs) is an important concern, especially in case of measuring separately the behaviour of one of the electrode when an overvoltage is applied. In this case a thin electrolyte-supported cell with the RE (Reference Electrode) coplanar with the WE (Working Electrode) is...

The suitability of electrochemical impedance spectroscopy measurements (EIS) in SOFCs is an important concern, especially in case of measuring separately the behaviour of one of the electrode when an overvoltage is applied. In this case a thin electrolyte-supported cell with the RE coplanar with the WE is experimentally convenient, but many...

In case of measuring separately the behavior of SOFC electrodes the concern of the reliability of impedance results was highlighted by many authors [1-3], especially when overpotentials are applied. A flat thin electrolyte-supported cell in a three-electrode configuration is often investigated, where the RE is deposited in a ring-shape around...
