dc.description.abstract | Herein, we developed a Mn1.3Co1.3Cu0.4O4 (MCCO) spinel for use as a new ORR catalyst for intermediate temperature solid oxide fuel cell (SOFC) applications. The addition of Cu to the (Mn,Co)(3)O-4 spinel effectively promoted the oxidation states of Mn ions, which were mostly positioned at octahedral sites. This effect facilitated small polaron hopping with a narrow band gap, resulting in high electrical conductivity of MCCO. An SOFC employing the MCCO-Sc0.1Zr0.89Ce0.01O1.95 composite cathode yielded extraordinarily high power-output values of 1.92 and 1.38 W cm(-2), at 800 and 700 degrees C, respectively. To the best of our knowledge, this result indicates the best performance among all SOFCs with any spinel-based cathodes to date. | - |
