MoO3 nanorods/Fe2(MoO4)3 nanoparticles composite anode for solid oxide fuel cells.

MoO 3 nanorods/Fe 2 (MoO 4 ) 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 MoO 3 nanorods/Fe 2 (MoO 4 ) 3 nanoparticles composite anode and a composite cathode consisting of Sr 0.9 Ce 0.1 CoO 3− δ and Sm-doped ceria (SDC). The peak power densities reach 225, 50, 75 mW cm −2 at 900 °C in H 2 , CH 4 and C 3 H 8 , respectively. The cell shows excellent long-term stability at 850 °C. The preliminary results demonstrate that the MoO 3 nanorods/Fe 2 (MoO 4 ) 3 nanoparticles composite is a promising alternative anode for solid oxide fuel cells. [ABSTRACT FROM AUTHOR]
