采用紫外纳米压印技术（UV-NIL）制备了La 0. 75 Sr 0. 25 Co 0. 50 Mn 0. 50 O3/掺钆氧化铈（LSCM/GDC）纳米复合材料的固体氧化物燃料电池（SOFC）阳极微图案。将LSCM/GDC纳米复合颗粒与UV固化树脂混合，然后UV压印在致密的氧化钇稳定的氧化锆（YSZ）基底上。在烧结过程中除去UV固化树脂后，UV-NIL衍生的微柱在YSZ基底上保持其结构。在制作出图案化SOFC阳极电极后，对其阻抗进行了实验研究。证明了所开发的方法制备微图案化复合SOFC材料的能力。
A micropatterned object composed of La0.75Sr0.25Co0.50Mn0.50O3/Gadolinium-doped Ceria (LSCM/GDC) nanocomposite was fabricated for anode of solid oxide fuel cells (SOFCs) via ultraviolet nanoimprint lithography (UV-NIL). The LSCM/GDC nanocomposite particles were mixed with UV-curable resin and then UV imprinted on a dense yttria-stabilized zirconia (YSZ) substrate. The UV-NIL derived micropillars kept their structure on the YSZ substrate after the UV-curable resin was removed in the sintering process. After fabrication of the patterned SOFC anode electrode, its impedance was experimentally investigated. The ability of the developed method to fabricate micropatterned composite SOFC materials was demonstrated.
