Abstract

MoO3 nanorods/Fe2(MoO4)3 nanoparticles composite has been prepared by a hydrothermal method combined with an in situ diffusion growth process. Single cells based on 300 μm LSGM electrolyte have been fabricated with the MoO3 nanorods/Fe2(MoO4)3 nanoparticles composite anode and a composite cathode consisting of Sr0.9Ce0.1CoO3−δ and Sm-doped ceria (SDC). The peak power densities reach 225, 50, 75 mW cm−2 at 900 °C in H2, CH4 and C3H8, respectively. The cell shows excellent long-term stability at 850 °C. The preliminary results demonstrate that the MoO3 nanorods/Fe2(MoO4)3 nanoparticles composite is a promising alternative anode for solid oxide fuel cells.
