Nanostructured　anodes　generate　massive　reaction　sites　to　oxidize　fuels　in　solid　oxide　fuel　cells　(SOFCs);　however,　the　nonexistence　of　a　practically　viable　approach　for　the　construction　of　nanostructures　and　the　retention　of　these　nanostructures　under　the　harsh　operating　conditions　of　SOFCs　poses　a　significant　challenge.　Herein,　a　simple　procedure　is　reported　for　the　construction　of　a　nanostructured　Ni–Gd-doped　CeO2　anode　based　on　the　direct　assembly　of　pre-formed　nanocomposite　powder　with　strong　metal–oxide　interaction.　The　directly　assembled　anode　forms　heterointerfaces　with　the　electrolyte　owing　to　the　electrochemical　polarization　current　and　exhibits　excellent　structural　robustness　against　thermal　ripening.　An　electrolyte-supported　cell　with　the　directly　assembled　anode　produces　a　peak　power　density　of　0.73 W　cm−2　at　800 °C,　while　maintaining　stability　for　100 h,　which　is　in　contrast　to　the　drastic　degradation　of　the　cermet　anode　prepared　using　the　conventional　method.　These　findings　provide　clarity　on　the　design　and　construction　of　durable　nanostructured　anodes　and　other　electrodes　for　SOFCs.　©　2023　Wiley-VCH　GmbH.
