Abstract

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 char- acterized showing full functionality. In addition, more complex con fi gurations of the electrolyte have been printed yielding an increase of the performance entirely based on geometrical aspects. Complementary, a nu- merical model has been developed and validated as predictive tool for designing more advanced con fi gurations that will enable highly performing and fully customized devices in the next future
