“…The GDC nanoparticles had a d -spacing value of approximately 2.71 Å, and the YCF crystal had a d -spacing value of approximately 2.57 Å, which were corresponding to the d-values from the XRD data (JCPDS nos. 01-075-0161 and 43-1036, respectively). , A single YCF–GDC core–shell fiber is illustrated in Figure S3 (Supporting Information), which also confirms the GDC nanoshell and core–shell microstructure.…”

Fibrous perovskite oxide has been the most promising cathode for intermediate-temperature solid oxide fuel cells (IT-SOFCs) due to its efficient mass and charge transfer. Herein, a core−shell fiber-structured YCo 0.5 Fe 0.5 O 3 (YCF)− Gd 0.1 Ce 0.9 O 1.95 (GDC) cathode is synthesized via the modified electrospinning technique. These unique YCF−GDC fibers exhibit a uniform diameter of 300 nm, and the GDC particles are attached to the YCF fiber cores. The electrochemical performance demonstrates a relatively low area-specific resistance of 0.66 Ω•cm 2 at 550 °C in air, which is much lower than 1.56 Ω•cm 2 of pure YCF fiber cathode. Moreover, the distribution of relaxation times (DRT) analysis results indicate that the introduction of GDC nanoparticles and the core−shell structure greatly facilitate oxygen-ion conduction and charge transfer processes, and the oxygen incorporation process plays a major role in the total polarization resistance. The NiO−GDC|GDC|fibrous YCF−GDC fuel cell shows a maximum power density of 426.5 mW•cm −2 at 550 °C. These results display that the core−shell fiber-structured YCF− GDC composite oxide is a promising candidate of highly active cathode for IT-SOFCs.
