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...

This study presents a physically-based model for the impedance simulation of the oxygen reduction reaction in porous strontium-doped lanthanum manganite (LSM) cathodes. The model describes the surface mechanism only, taking into account the co-limited adsorption/diffusion of oxygen and the charge-transfer reaction at the three-phase boundary...
