dc.description.abstractYttria-stabilized zirconia (YSZ)-based symmetrical solid oxide fuel cells (SSOFCs) are among the most attention-grabbing research directions to accelerate the commercialization of SOFCs due to the great advantages in reducing material and fabrication costs, improving thermomechanical compatibility between components, and enhancing the ability of coking tolerance or sulfur poisoning, but they suffer from low output performance. Here we present a new nanoengineering electrode strategy of PrOx nano-catalyst infiltrated Pr0.6Sr0.4FeO3-delta (PrOx-PSF) for YSZ-based SSOFCs operating at intermediate temperature and achieving superior output performance. After infiltration, PrOx nanoparticles are uniformly distributed on the porous PSF perovskite electrode surface which is confirmed by TEM. The infiltrated symmetrical cell PrOx-PSF|YSZ|PSF-PrOx exhibits very low polarization resistance (R-p) of 0.053 omega cm(2) and 0.113 omega cm(2) at 800 ? in air and humidified hydrogen, respectively. Integration of nanoengineering electrode into state-of-the-art electrolyte-supported single cell achieves superior output performance of 741, 601, 486, and 250 mW cm(-2) at 800, 750, 700, and 650 ?, respectively. It is because nanoengineered PrOx infiltrated PSF shows the highest catalytic activity for both oxygen reduction reaction (ORR) and hydrogen oxidation reaction (HOR). Moreover, the single-cell shows long-term stability without performance degradation at intermediate temperatures (700 ?) on YSZ electrolyte without any buffer layer at constant 0.7 V applied voltage. Therefore, the novel PrOx-PSF nanostructured electrode can greatly promote the output performance of symmetrical SOFCs.
