A novel CoFeZrAl-oxide (CFZA) consisted of FeAl2O4, Co3O4 and ZrO2 was prepared by an auto ignition process, displaying a typical morphology of nanorods. The corresponding fuel cell was constructed by using CFZA as the ion-conducting membrane, incorporated between two layers of Ni0.8Co0.15Al0.05Li-oxide pasted on nickel foam (Ni-NCAL), which was used as both electrodes and current collectors. The fuel cell presented an open circuit voltage of 1.07 V and maximum power density of 631 mW/cm(2) at 600 degrees C. The reduction of FeAl2O4 to oxygen-deficient FeAl2O4 (delta) under H-2 condition contributed to the ionic conduction, then the ionic conductor FeAl2O4 (-) (delta) composited with insulator ZrO2 to further enhance the ionic conductivity due to composite effect.
