Research on SOFC of Composite Anode Material SrMoO<sub>3</sub>-YSZ Impregnated with Gd<sub>0.2</sub>Ce<sub>0.8</sub>O<sub>1.9</sub> by Hard Template Method

Abstract

Solid oxide fuel cell (SOFC) anodes made by SrMoO3 substituting for Ni of SOFC. Porous SrMoO3 and YSZ (8mol%Y2O3-ZrO2) were synthesized with activated carbon hard template by liquid phase method, and nanoparticles Gd0.2Ce0.8O1.9 (GDC) impregnated porous SrMoO3-YSZ with liquid phase immerse method, thus SOFC composite anode material was synthesized. SrMoO3-YSZ that impregnated with GDC by hard template method was treated as the anode, YSZ as the electrolyte while LSM (La0.8Sr0.2MnO3-d) as the cathode, so that the solid oxide fuel cell could be assembled. At 800°C, the highest power densities of cells with the anode of SrMoO3-YSZ impregnated by GDC and the cell anode of SrMoO3-YSZ were 190.44mW•cm-2 and 98.06 mW•cm-2 respectively as methane was the fuels.
