HIGH IONIC CONDUCTIVE CERIA ELECTROLYTE FOR INTERMEDIATE-TEMPERATURE SOLID OXIDE FUEL CELLS

摘要

The present invention relates to a ceria electrolyte for a solid oxide fuel cell and, more specifically, to a ceria electrolyte for a solid oxide fuel cell. The ceria electrolyte (CeO_2) is stable by substituting oxides and ytterbium oxide (Yb_2O_3) selected from gadolinium oxide (Gd_2O_3) or samarium oxide (Sm_2O_3). In addition, the ytterbium oxide (Yb_2O_3) is substituted by 2 to 4 mol%.
