dc.description.abstract | Developing electrocatalysts with enhanced catalytic activities in oxygen reduction reactions (ORRs) and oxygen evolution reactions (OERs) is crucial for achieving high-performance solid oxide electrochemical cells (SOCs) at reduced temperatures. Herein, a nanostructured spinel Mn1.3Co1.3Cu0.4O4 (MCCO)-based bifunctional oxygen electrode is developed for the ORR and OER using an infiltration process. A uniform distribution and percolated network of MCCO on a Sc-stabilized ZrO2 (ScSZ) backbone without agglomeration is achieved by controlling the polymeric agent and catalyst loading. SOCs with the nanostructured MCCO-ScSZ electrode exhibited superior electrochemical performance of similar to 2.2 W/cm(2) in the fuel cell mode and similar to 1.4 A/cm(2) at 1.3 V in the electrolysis mode at 750 degrees C. To date, these results show the best performance for SOCs using spinel-based oxygen electrodes. Thus, our findings demonstrate that the nanoengineered MCCO catalyst has enormous potential as a bifunctional oxygen electrode for high-performance reversible SOCs at reduced temperatures. | - |
