Abstract:
The innovation process describes the process and results for fabrication of a magnetron sputter deposited fully dense electrolyte layer (8YSZ/GDC/LSGM) embedded in a high performance membrane electrolyte assembly (MEA) (Unit Cell) of Solid Oxide Fuel Cell. A single cell with airtight electrolyte layer (8YSZ/GDC/LSGM) is prepared via thin film technique of magnetron sputter deposition, combined with SOFC-MEA processing methods (such as tape casting, lamination, vacuum hot pressing, screen printing, spin coating, and plasma spray coating) and sintering optimization conditions. The gas permeability of the electrolyte layer is below 1×10−6 L/cm2/sec and the open circuit voltage/power density of the single cell performance test exceeds 1.0 V and 500 mW/cm2.
