抄録

The electric power produced by a Ni/Gd-doped ceria (GDC) anode-supported solid oxide fuel cell with a GDC electrolyte (40 µm thick) and a (La_0.8Sr_0.2)(Co_0.8Fe_0.2)O₃ (LSCF) cathode using a 3 vol % H₂O-containing H₂ fuel was measured. The addition of 10 or 50 mass % GDC powder (Ce_0.8Gd_0.2O_1.9) to the LSCF cathode reduced the power density from 320 mW/cm² in the case of no GDC to 137 or 122 mW/cm², respectively. The added GDC particles blocked the conduction path between LSFC particles. The as-prepared LSCF powder was ball-milled using α-Al₂O₃ balls. The milling decreased the charge transfer resistance at the cathode and increased the power density of the fuel cell.
