The unique characteristics of nanofibers in rational electrode design enable effective utilization and maximizing material properties for achieving highly efficient and sustainable CO<sub>2</sub> reduction reactions (CO<sub>2</sub>RRs) in solid oxide electrolysis cells (SOECs). However, practical application of nanofiber-based electrodes faces challenges in establishing sufficient interfacial contact and adhesion with the dense electrolyte. To tackle this challenge, a novel hybrid nanofiber electrode, La<sub>0.6</sub>Sr<sub>0.4</sub>Co<sub>0.15</sub>Fe<sub>0.8</sub>Pd<sub>0.05</sub>O<sub>3-δ</sub> (H-LSCFP), is developed by strategically incorporating low aspect ratio crushed LSCFP nanofibers into the excess porous interspace of a high aspect ratio LSCFP nanofiber framework synthesized via electrospinning technique. After consecutive treatment in 100% H<sub>2</sub> and CO<sub>2</sub> at 700 °C, LSCFP nanofibers form a perovskite phase with in situ exsolved Co metal nanocatalysts and a high concentration of oxygen species on the surface, enhancing CO<sub>2</sub> adsorption. The SOEC with the H-LSCFP electrode yielded an outstanding current density of 2.2 A cm<sup>-2</sup> in CO<sub>2</sub> at 800 °C and 1.5 V, setting a new benchmark among reported nanofiber-based electrodes. Digital twinning of the H-LSCFP reveals improved contact adhesion and increased reaction sites for CO<sub>2</sub>RR. The present work demonstrates a highly catalytically active and robust nanofiber-based fuel electrode with a hybrid structure, paving the way for further advancements and nanofiber applications in CO<sub>2</sub>-SOECs.
