摘要：
Uniformly distributed CuFe bimetallic alloy (CFA) nanoparticle-decoratedRuddlesden-Popper (RP) structure PrSr(Cu,Fe)(0.9)Mn0.1O4-delta perovskite (RP-PSCFM-CFA) hadbeen synthesized by in situ annealing cubic perovskitePr(0.5)Sr(0.5)Cu(0.1)Fe(0.8)Mn(0.1)O(3-delta) in a wet H-2 atmosphereat 800 degrees C. The precipitated nanoparticles effectively improvedthe electrochemical properties of the RP-PSCFM-CFA when it was usedas the solid oxide fuel cell anode. The La0.8Sr0.2Ga0.83Mg0.17O3-delta electrolyte-supportedsingle cell can reach maximum power densities of 0.996 and 0.410 Wcm(-2) in H-2 and C3H8 at 800 degrees C, respectively. Moreover, the single cell showed asuperior stable performance in C3H8 at 800 degrees Cwith a constant current density of 0.8 A cm(-2), indicatingthat the RP-PSCFM-CFA anode has an excellent catalytic capacity andcertain anticarbon performance. This study offers the possibilityof further extensive development of Cu-based perovskite anodes.
