  Focused ion beam (FIB)-scanning electron microscopy (SEM) allowed the
characterization of the microstructure of two solid oxide fuel cells prepared
at different sintering temperatures. 3D volume reconstruction showed that a
relatively low sintering temperature significantly and positively affected
distribution, volume and particle size of yttria-stabilized zirconia, nickel,
and pore phases inside the anode, as well as the extent of the important
triple-phase boundary interface.
