Fabrication and evaluation of anode and thin Y2O3-stabilized ZrO2 film by co-tape casting and co-firing technique

Fabrication and characterization of Ni-SSZ gradient anodes/SSZ electrolyte for anode-supported SOFCs by tape casting and co-sintering technique

“…The difference in ohmic resistance (0.079 U cm 2 at 800 C) was probably due to the value of the cath-ode ohmic resistance, and the contact resistance between the current collector and electrode surfaces [40]. As shown in Table 3, the results were comparable with many other anode-supported SOFCs [6,14].R p of cell with graded Ni-SSZ anode was lower than that of non-gradient Ni- [33] 0.17 Le [14] 0.135 Zhou [6] 0 [33] 0.62 Le [14] 0.31 Zhou [6] 0.272 i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 4 0 ( 2 0 1 5 ) 8 4 3 3 e8 4 4 1 SSZ anode, because the cell with graded Ni-SSZ anode had lower anodic gas diffusion polarization resistance (R 4 ), the result indicated graded Ni-SSZ anode structure improved the performance of cell. The cathodic electrochemical polarization resistance (R 1 ) was higher than anodic electrochemical polarization resistance (R 2 ).…”

“…The single cell with graded Ni-SSZ anode showed better performance than that of cell with non-gradient Ni-SSZ anode. The results were also higher than many other anode-supported SOFCs [6,14,33,40], and was attributed to the fact that the anode layers with continuous porosity gradient provided rich fuel gas channels and electrochemical active TPBs.…”

“…The electrolyte must be dense enough after sintered at a high temperature, the anode must possess enough pores which can be attained by adding pore former for diffusion of fuel gas [13]. Recently, many researchers have reported that co-sintering process is a useful method for manufacturing anode-supported electrolyte film [14,15]. The whole structure of Ni-YSZ anode substrate/YSZ electrolyte could be attained by the one-step co-sintering at 1400 C for 5 h. The co-sintering technique is the simultaneous fabrication of electrolyte and supporting anode, which could increase productivity and reduce fabrication cost [16,17].…”

Fabrication and characterisation of a large-area solid oxide fuel cell based on dual tape cast YSZ electrode skeleton supported YSZ electrolytes with vanadate and ferrite perovskite-impregnated anodes and cathodes

“…Two layers of green tape containing YSZ and 65 wt % and 85 wt. % graphite (compared to the weight of YSZ) were cast sequentially on the top of the ysz green tape with 1-hour interval for drying [22].Two co-cast green tapes were laminated together ( Figure 1 (a)) to produce a tri-layer green tape for YSZ wafer. The green tapes were fired at 1400 o C for 5 hours on a zirconia plate to prepare the scaffold for impregnation (Figure 1 (b)).…”
