Anode material for solid oxide fuel cell should have a high electrocatalytical activity including a rapid charge transfer as well as high absorption/desorption rates and rapid surface diffusivity of the electrochemical active species to provide a low polarization resistance at the interface. For efficient operation the electrochemical reaction must proceed in the volume (in three dimensions). Therefore, the morphology of the anode is very important for realizing optional "three-phase boundary" structure [1].
The aim of this work is the investigation of electrochemical activity and stability of Ni-YSZ cermet anode prepared by co-precipitation
