Abstract

The cathode efficiency for intermediate temperature solid oxide fuel cells is largely limited by the catalytic activity for oxygen reduction reaction. Here by, we design and synthesize CuCo₂O₄ decorated Er_0.4Bi_1.6O₃ cathode by means of a simple gelation method and then screen-print it on scandium-stabilized zirconia electrolyte cell followed by a relatively lower temperature sintering process. The decoration of CuCo₂O₄ adequately enhances the electro-catalytic activity of the composite cathode for the ORR. In addition, Er_0.4Bi_1.6O₃ matrix also reduces the sintering temperature (from 1000 °C to 850 °C) compared to the pristine CuCo₂O₄ electrode. The CuCo₂O₄-decorated-Er_0.4Bi_1.6O₃ composite cathode demonstrates a lower polarization resistance (0.016 Ω cm² at 800 °C) in air, exhibiting an 87% decrease in comparison to the primary CuCo₂O₄ cathode.
