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.

增材制造代表着一场革命，因为它具有独特的能力，可以自由成形近净形状的产品，并大大减少了废料和资金成本。这些不公平的优势尤其适用于昂贵且耗能的先进陶瓷制造工艺，例如氧化钇稳定的氧化锆，这是固体氧化物燃料电池应用中的最先进电解质。在这项研究中，氧化钇稳定的氧化锆的自支撑电解质已经通过使用立体光刻三维打印机进行了打印。分别用镧锶锰酸锰和氧化镍-氧化钇稳定的氧化锆复合材料的阴极和阳极层制成的印刷电解质和完整电池经过电化学表征，显示出完全的功能性。此外，电解质的更复杂的配置已被印刷，从而完全基于几何方面提高了性能。作为补充，已经开发了数值模型并将其作为预测工具进行验证，以用于设计更高级的配置，以在未来的将来实现高性能和完全定制的设备。
