Solid　oxide　fuel　cells　(SOFCs)　are　the　most　efficient　energy　conversion　technology　to　convert　the　chemical　energy　of　fuels　like　hydrogen,　natural　gas,　etc.　to　electricity.　However,　one　of　the　limiting　factors　in　the　commercial　viability　of　SOFCs　technologies　is　the　time-consuming　and　high-cost　multiple　cell　fabrication　processes.　Here,　we　report　the　development　of　a　facile　procedure　for　the　preparation　of　an　electrolyte-supported　cell　with　a　Ni-Gd0.1Ce0.9O1.95　composite　anode　and　a　La0.6Sr0.4Co0.2Fe0.8O3-δ　cathode,　and　the　fabrication　procedure　of　the　electrodes　decreases　from　four　steps　of　screen-printing　and　sintering　of　conventional　cell　preparation　processes　to　two　steps　of　screen-printing　using　a　direct　assembly　approach　without　the　high-temperature　sintering　steps.　The　most　important　observation　is　the　simultaneous　formation　of　the　electrode/electrolyte　interfaces　of　both　the　anode　and　cathode　by　in　situ　passing　a　current　through　the　directly　assembled　cells　at　800　℃.　The　power　density　of　the　directly　assembled　cell　reaches　0.41　W　cm−2　at　a　voltage　of　0.7　V　and　800　℃,　close　to　0.46　W　cm−2　of　the　sintered　cell.　The　directly　assembled　cell　shows　comparable　operational　stability　to　the　sintered　cell　at　800　℃　for　100　h.　This　work　sheds　light　on　the　facile　fabrication　of　electrolyte-supported　cells　with　substantially　simplified　preparation　procedures　and　reduced　costs.　©　2022
