Anode morphology and performance of micro-tubular solid oxide fuel cells made by aqueous electrophoretic deposition

► Consecutive aqueous EPD plus single-step co-sintering was employed to make anode-supported micro-tubular SOFC. ► Suspension behavior of the 8YSZ-NiO composite slurry is dominated by NiO. ► Deposition rate increases with current density and solid loading but decreases with surfactant concentration. ► Porosity decreases with increasing deposition rate. ► The highest power density was obtained for the anode containing 70 wt% NiO.
