Solid　oxide　electrolysis　cell　as　an　energy　conversion　device,　has　attracted　much　attention　in　recent　years　due　to　its　high　efficiency　and　capacity.　In　this　work,　we　prepare　the　metal　oxide　materials,　Ce0.9(NixCu1-x)0.1O2-d　(x　=　0-1),　and　alloy　Ni/Cu　nanoparticles　are　exsolved　from　the　CeO2　surface　after　treatment　in　an　H2/Ar　reducing　atmosphere,　which　is　formed　the　metal-oxide　interfaces.　The　current　density　reaches　0.51　A　cm-2　at　700　&　DEG;C,　1.0　V　and　the　ethane　conversion　rate　is　38.9%　with　the　ethylene　yield　of　24.9%,　and　it　demonstrates　outstanding　stability　even　after　being　operated　continuously　for　a　period　of　one　hundred　hours.　The　material　with　in-situ　precipitation　metal-oxide　interface　shows　significantly　enhanced　ethane　electrolytic　activity,　which　is　also　confirmed　by　density　functional　theory.　This　work　demonstrates　the　potential　application　of　electrochemical　ethane　oxidative　dehydrogenation.
