All rights reserved.Doped ceria is believed as the promising candidate for IT-SOFC electrolyte. Codoped strategy can increase the conductivity of single doped ceria at lower operating temperature. The purposes of this research were to synthesize and characterize several codoped ceria Ce1-x-yGdxMyO2-γ, M = Er, Dy, or Nd and 0.0 ≤ x,y ≤ 0.1. Solid state method was used due to it is a simple and suitable method for pilot scale. For the same total dopant concentration, the correlation between cation mean radii and the lattice parameter followed the Vegard’s rule. The activation energies of codoped ceria were lower than 1 eV and most of codoped ceria showed conductivities higher than 10-2 S.cm-1 at intermediate temperature range (500-800°C).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cerium oxides,Co-doped,Co-doped cerias,Dopant concentrations,Intermediate temperatures,IT-SOFCs,Operating temperature,Solid state method[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Cerium oxide,Codoped,IT-SOFC,Solid electrolyte[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
