For these purposes, anode materials based on double perovskite structure, A2BB’O 6, were synthesized and studied. In this work, double perovskite compounds, Sr2Mg1-xMnxMoO6-δ (SMMMO) with 0≤×≤1, were synthesized by means of solid state reaction technique at 1350°C. Crystal structures were determined using X-rays diffractometer and analyzed with the RIETICA program, by employing Le Bail method. The oxides materials showed to adopt monoclinic structure with space group of P21/n. For SMMO with higher x, the lattice parameters and the unit-cell volume become smaller. SEM (Scanning Microscope Electron) image, which gave the morphology of SMMMO showed that grains size was increased with the increasing of x. Meanwhile, the DC measurement for electrical conductivity as function of temperature revealed that the conductivity increases with the increasing of x. © 2008 American Institute of Physics.[/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][/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]Double perovskite,SMMO,SOFC,X-ray diffraction[/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]https://doi.org/10.1063/1.2906056[/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]
