CATHODE COMPOSITION CONTAINING FLUORINE FOR CARBON DIOXIDE DECOMPOSITION, SOLID OXIDE ELECTROLYSIS CELL FOR CARBON DIOXIDE DECOMPOSITION AND MANUFACTURING METHOD FOR THE CATHODE COMPOSITION

摘要

An object of the present invention is to provide a cathode composition doped with fluorine for a solid oxide electrolytic cell that electrolyzes carbon dioxide to generate carbon monoxide with high efficiency and high performance. A first aspect of the present invention for solving the above problems is to provide a cathode composition of a solid oxide electrolytic cell for decomposing carbon dioxide, including a compound of the following [Formula 1]. [Formula 1] A 2-x BO 4-y-δ F y (Wherein, A includes at least one element selected from the lanthanide group or alkaline earth metal, and B includes at least one element selected from among transition metals and rare earth metals. x and y are positive numbers between 0 and 0.5, and δ is 0 and 1 It is a value that makes the compound of [Formula 1] electrically neutral)
