Electrochemical and Microstructural Chacteristics of LSCF-GDC Composite Cathodes for Intermediate-Temperature Solid Oxide Fuel Cells |
| 초록 |
Intermediate temperature operation (ranging from 550 to 700℃) has attracted the wide-spread attention in solid oxide fuel cells. The intermediate temperature solid oxide fuel cells (IT-SOFCs) have been exploited using a ceria-based electrolyte as the basis components. The technical success depends on the optimized cell performance where the key components of electrodes and electrolytes should be developed. La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) has been reported to exhibit mixed conduction unlike that of La1-xSrxMnO3(LSM). The particular feature of LSCF is combined with the Gd2O3-Doped Ceria(GDC) which functions as a cathode composite for IT-SOFCs. The electrode polarizations are characterized at the intermediate temperature ranging from 500℃ to 700℃. The optimized information is discussed in terms of electrochemical performance and microstructural features. |
