The ASCs were successfully prepared by using fish oil as pore former.
The Pmax of the cell using pore former could reach 0.754 W cm−2 at 850 °C.
The P0.7V is about 1.6 times that of the pristine cell at 750 °C.
Rc values of the pristine cell are about 2.34 times that of the above cell at 850 °C.
The cell showed a low degradation under constant current discharge.
