“…Due to environmental, health, safety, and economic reasons, aqueous-based tape casting method using water as a solvent is adopted to replace the traditional organic-based tape casting method [15]. Despite these advantages, several critical challenges should be overcome which include slow drying rate of the tape, high crack sensitivity, low strength of water-soluble binders, and the agglomeration of powders due to hydrogen bonding [16][17][18]. Also, ceramic powder as main constituent of slurry plays an important role in suspension composition.…”

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. Microstructures and mechanical properties such as flexural modulus, bending strength, and microhardness of tapes sintered at 1,300–1,500 °C have been evaluated. Indentation fracture toughness was also determined by the method of Palmqvist cracks at different applied loads for tapes sintered at 1,500 °C. Grain size measurements showed that excessive grain growth occurred during sintering despite using 10GDC nanopowders as the starting material. However, mechanical properties of sintered tapes improved by increasing sintering temperature and the results are comparable with those reported for 10GDC in literature.

“…On the other hand, Cell 3 with a double-layered cathode showed a larger OCV and a higher maximum density of 0.71 W/cm 2 , which is rather good performance in this LSCF-GDC/GDC/NiO-GDC system. 19,25,26 These results seem to be related to the microstructure development of cathode layers during the heating stage, since these three cells here have the same anode and electrolyte sheets.

“…The first point is to developed new electrolyte material with higher ionic conductivity and the second is to decrease the electrolyte thickness, developing the electrode-supported SOFC [4,5]. GDC electrolyte has an ionic conductivity higher than of yittria stabilized zirconia (YSZ) and a thermal expansion coefficient much closer to that of the Ni-cermet and commercial ferrite stainless interconnects compared to YSZ, making the GDC a very good candidate to electrolyte material [6].…”

Studies have been developed in last decades in order to produce NiO-based material to be used as anode in solid oxide fuel cell (SOFC). Aqueous-based tape casting was used to produce NiO-GDC substrates with smooth and homogeneous surfaces and good flexibility. Physical and mechanical properties were obtained in green tapes sintered at temperatures ranging from 1200 to 1400 ͦ C. The tapes sintered in 1400 ͦ C showed the best density and porosity values and mechanical strength between 7 and 25 MPa. SEM micrographs show a dense material with cracks and pores. The sintered material shows the presence of nickel oxide and gadolinium cerium oxide.
