Application as a Solid Oxide Fuel Cell Cathode

研究领域：SOFC燃料电池 方法：IV特性和交流阻抗 范围1MHz - 0.1Hz
The feasibility of using the thin film technology in utilizing lanthanum strontium manganite (LSM) for a solid oxide fuel cell
(SOFC) cathode in a low-temperature regime is investigated in this study. Thin film LSM cathodes were fabricated using pulsed
laser deposition (PLD) on anode-supported SOFCs with yttria-stabilized zirconia (YSZ) electrolytes. Although cells with a 1 mthick
LSM cathode showed poor low-temperature cell performance compared to that of a cell with a bulk-processed cathode due
to the lack of a triple-phase boundary length, the cell with 200 nm-thick gadolinia-doped ceria (GDC) inserted between the LSM
and YSZ showed enhanced performance and more stable operation characteristics in a comparison of a cell without a GDC layer.
We postulate that the GDC layer likely improved the cathode adhesion, therefore contributing to the improvement of the cell performance instead of serving as an interfacial reaction buffer.
