简介
Ni-free solid oxide fuel cell ceramic anode consisting of Ruddlesden–Popper type layered perovskite (Pr0.4Sr0.6)3(Fe0.85Nb0.15)2O7 (RP-PSFN) matrix with homogenously dispersed CoFe bi-metallic alloy (CFA) nanoparticles has been fabricated by in situ annealing the porous perovskite Pr0.4Sr0.6Co0.2Fe0.7Nb0.1O3−δ membrane in H2 at 900 °C. The RP-PCFN-CFA ceramic anode has demonstrated a similar catalytic activity to Ni-based ceramic anode. La0.8Sr0.2Ga0.83Mg0.17O3−δ 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 °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 °C, indicating an excellent coking resistance.
