摘要：

Ni-free solid oxide fuel cell ceramic anode consisting of Ruddlesden-Popper type layered perovskite (Pr0.4Sr0.6)(3)(Fe0.85Nb0.15)(2)O-7 (RP-PSFN) matrix with homogenously dispersed CoFe bi-metallic alloy (CFA) nanoparticles has been fabricated by in situ annealing the porous perovskite Pr0.4Sr0.6 Co0.2Fe0.7Nb0.1O3-delta membrane in H-2 at 900 degrees C. The RP-PCFN-CFA ceramic anode has demonstrated a similar catalytic activity to Ni-based ceramic anode. La0.8Sr0.2Ga0.83Mg0,17O3-delta electrolyte supported SOFC single cell with RP-PSFN-CFA anode generates maximum power outputs of 0.59 and 0.92 W cm(-2) in wet C3H8 (3 vol% H2O) at 800 and 850 degrees C, respectively. Moreover, the single cell shows a stable power output under a constant current load of 0.40 A cm(-2) in wet C3H8 at 800 degrees C, indicating an excellent coking resistance. (C) 2014 Elsevier Ltd.
