A colloidal deposition without any binder was developed to prepare a dense La 0.8 Sr 0.2 Ga 0.85 Mg 0.15 O 3−δ (LSGM) film on porous NiO/YSZ substrates, using an incompletely crystallized LSGM powder as starting material. Both the dense LSGM film with a thickness of 15 μm and the required phase composition of the LSGM were achieved simultaneously by sintering at 1400°C for 6 h. The conductivity of the supported LSGM film attained 0.102 S/cm at 800°C, which was comparable with those of the self‐supported LSGM films. The maximum power density of the LSGM film cell was 480 at 800°C and 614 mW/cm 2 at 850°C, respectively.
