A perovskite-type Nd0.75Sr0.25Co0.8Fe0.2O3−δ cathode for advanced solid oxide fuel cells†
Abstract
Perovskite-type Nd0.75Sr0.25Co0.8Fe0.2O3−δ (NSCF) has shown excellent oxygen reduction reaction (ORR) properties (an area specific polarization resistance of 0.1 Ω cm2 at 700 °C) as a composite cathode (30 wt% La0.8Sr0.2Ga0.8Mg0.2O3−δ (LSGM)) with remarkable chemical stability under CO2. The mechanism for the ORR was established employing pO2 and temperature dependent studies.
