  Additive manufacturing represents a revolution due to its unique capabilities
for freeform fabrication of near net shapes with strong reduction of waste
material and capital cost. These unfair advantages are especially relevant for
expensive and energy-demanding manufacturing processes of advanced ceramics
such as Yttria-stabilized Zirconia, the state-of-the-art electrolyte in Solid
Oxide Fuel Cell applications. In this study, self-supported electrolytes of
yttria-stabilized zirconia have been printed by using a stereolithography
three-dimensional printer. Printed electrolytes and complete cells fabricated
with cathode and anode layers of lanthanum strontium manganite- and nickel
oxide-yttria-stabilized zirconia composites, respectively, were electrochemical
characterized showing full functionality. In addition, more complex
configurations of the electrolyte have been printed yielding an increase of the
performance entirely based on geometrical aspects. Complementary, a numerical
model has been developed and validated as predictive tool for designing more
advanced configurations that will enable highly performing and fully customized
devices in the next future
