Mechanical properties of Gd-CeO2 electrolyte for SOFC prepared by aqueous tape casting
Mechanical properties of gadolinium-doped ceria (Ce0.9Gd0.1O1.95, 10GDC) green tape prepared by aqueous-based tape casting process were characterized by tensile test and shear punch test (SPT). SPT was found to be a useful method for characterizing mechanical properties of green tapes. Microstructur...
