Ammonia effects on the electrochemical and structural properties for SOFC cathodes |
| 초록 |
Commercialization of solid oxide fuel cell (SOFC) requires excellent electrode materials and easy manufacturing. Among the various SOFC fabrication methods, infiltration technology is advantageous to enhance the electrochemical performance by forming nano-sized particles. However, it takes a long time to satisfy the efficient loading of the electrode materials. To resolve this problem, herein, a highly concentrated precursor solution is prepared by adding ammonia as a chelate agent. The addition of ammonia realizes a highly concentrated precursor solution by increasing the solubility of the precursor compared to the typical precursor solution using only citric acid. Furthermore, we investigated the effect of ammonia on the electrode microstructure, phase, electrochemical performance, and fabrication procedure. |
