Abstract

The bulk volume of the dense NiO phase dramatically contracted upon reduction, while the YSZ phases are completely unaffected. No cracks or particle detachment are observed either at the interface of the anode/electrolyte or in the anode backbone. Compared with the initial NiO state (as-prepared), the area of Ni phase contracts by 22.6%-83.7%, depending on the grain size.
