H2 and CH4 oxidation on Gd0.2Ce0.8O1.9 infiltrated SrMoO3-yttria-stabilized zirconia anode for solid oxide fuel cells

Strontium molybdate (SrMoO3) as an electronic conductor was incorporated with yttria-stabilized zirconia (YSZ) to form an anode scaffold for solid oxide fuel cells. Gd0.2Ce0.8O1.9 (GDC) nanoparticles were introduced by wet impregnation to complete the Ni-free GDC infiltrated SrMoO3–YSZ anode fabrica...

Gd0.2Ce0.8O1.9 (GDC) nanoparticles were introduced by wet impregnation to complete the Ni-free GDC infiltrated SrMoO3–YSZ anode fabrication. The effects of SrMoO3 on the electrode conductivity and GDC infiltration on the catalytic activity were examined. A pronounced performance improvement was observed both on wet H2 and CH4 oxidation for the 56 wt.% GDC infiltrated SrMoO3–YSZ. In particular, the polarization resistance decreased from 8 Ω cm2 to 0.5 Ω cm2 under wet H2 (3% H2O) at 800 °C with the introduction of GDC. Under wet CH4 at 900 °C, a maximum power density of 160 mW cm−2 was obtained and no carbon deposition was observed on the anode. It was found that the addition of H2O in the anode caused an increase of electrode ohmic resistance and a decrease of open circuit voltage. Redox cycling stability was investigated and only a slight drop in cell performance was observed after 5 cycles. These results suggest that GDC infiltrated SrMoO3–YSZ is a promising anode material for solid oxide fuel cells. 2013-07-16T06:16:02Z 2019-12-06T19:36:24Z 2013-07-16T06:16:02Z 2019-12-06T19:36:24Z 2012 2012 Journal Article Xiao, P., Ge, X., Zhang, L., Lee, J.-M., Wang, J.-Y., & Wang, X.
