dc.description.abstract | Fe- and Cu-doped SmBaCo2O5+delta (FC-SBCO)-Ce0.9Gd0.1O1.95 (CGO) composites with various CGO contents (0-40 wt.%) are investigated as new cathode materials for intermediate-temperature solid oxide fuel cells (IT-SOFCs) based on a Ce0.9Gd0.1O1.95 electrolyte. The effect of CGO incorporation on the thermal expansion coefficient (TEC), electrochemical properties and thermal stability of the FC-SBCO-CGO composites is investigated. A composite cathode of 30 wt.% CGO-70 wt.% FC-SBCO (CS30-70) coated on a Ce0.9Gd0.1O1.95 electrolyte shows the lowest area specific resistance (ASR), i.e., 0.049 Omega cm(2) at 700 degrees C. The TEC of the CS30-70 cathode is 14.1 x 10(-6) degrees C-1 up to 900 degrees C, which is a lower value than that of the FC-SBCO (16.6 x 10(-6) degrees C-1) counterpart. Long-term thermal stability and thermal cycle tests of the CS30-70 cathode are performed. Stable ARS values are observed during both type of test. An electrolyte-supported (300-mu m thick) single-cell configuration of CS30-70/CGO/Ni-CGO delivers a maximum power density of 535 mW cm(-2) at 700 degrees C. The unique composite composition of CS30-70 demonstrates improved electrochemical performance and good thermal stability for IT-SOFCs. (C) 2010 Elsevier B.V. All rights reserved. | - |
