Research on SOFC of Composite Anode Material SrMoO₃-YSZ Impregnated with Gd_0.2Ce_0.8O_1.9 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 Gd_0.2Ce_0.8O_1.9 (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 (La_0.8Sr_0.2MnO_3-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.
