Long-term Testing and Analysis of a ScSZ / LaSrCuFe Cell
Jürgen Wackerl,백동현,Torsten Markus 한국세라믹학회 2008 한국세라믹학회지 Vol.45 No.12
An electrolyte supported SOFC cell was tested at 800oC in air for 3600 h with an applied current density of 200 mA/cm² to examine possible cathode degradation issues. A scandium- stabilized zirconia (ScSZ) with additional manganese doping (ScSZ: Mn) was used as electrolyte. A strontium and copper-doped lanthanum ferrite (LaSrCuFe) and platinum were used as cathode and quasi-anode material, respectively. The DC resistance was logged over the complete testing period. Additionally, impedance spectroscopy was used from time to time to track changes of the cell in-situ. Post-test analysis of the cell using methods like scanning electron microscopy imaging and other electrochemical testing methods allow the identification of different degradation sources. The results indicate a promising combination of electrolyte and cathode material in terms of chemical compatibility and electrical performance.
