The effect of solids loading on the screen-printing and properties of nickel/scandia-stabilized-zirconia anodes for solid oxide fuel cells

► Solids content is a critical factor in controlling the rheology of SOFC anode screen-printing inks. ► Ink viscosity, thixotropic properties and particle network strength increase with increasing solids content. ► The improved particle network strength within the inks was determined critical to optimize film properties. ► Inks having 28-30 vol% solids were determined optimum for SOFC anode fabrication.
