Copper cobalt spinel as a high performance cathode for intermediate temperature solid oxide fuel cells

CuCo 2 O 4 spinel prepared via an EDTA-citric acid process was studied as a candidate solid oxide fuel cell (SOFC) cathode material at intermediate temperatures (IT). CuCo 2 O 4 cathodes were measured using thermal gravimetric analysis, X-ray diffraction and scanning electron microscopy. AC impedanc...

description CuCo 2 O 4 spinel prepared via an EDTA-citric acid process was studied as a candidate solid oxide fuel cell (SOFC) cathode material at intermediate temperatures (IT). CuCo 2 O 4 cathodes were measured using thermal gravimetric analysis, X-ray diffraction and scanning electron microscopy. AC impedance spectroscopy and DC polarization measurements were used to study the electrode performance. The obtained value of the polarization resistances at 800 °C was 0.12 Ω cm 2 with a maximum power density of 972 mW cm −2 . CuCo 2 O 4 spinel prepared via an EDTA-citric acid process was studied as a candidate solid oxide fuel cell (SOFC) cathode material at intermediate temperatures (IT).
