A novel multilayer aqueous tape casting method for anode-supported planar solid oxide fuel cell

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.…”

“…Therefore, governing the cosintering behavior by the heat treatment was an effective method [32,33]. As shown in Fig.…”

Graded porous solid oxide fuel cells fabricated by multilayer tape casting and co-firing progress

“…The power density at 800 °C is more than twofold that for a similar cell Ni/Ni-YSZ/YSZ/LSCF fabricated by a deposition and co-sintering process in a previous report [23]. These power outputs are also higher than that of the same cell with LSM-SSZ cathode, specifically, 800, 550, and 370 mW•cm −2 at the corresponding temperatures [24].

Preparation and Characterization of Palladium Nanoparticles Supported on Nickel Hexacyanoferrate for Fuel Cell Application

“…[1][2][3] Although supported Pd NPs catalysts have excellent electrocatalytic activity in oxygen reduction reactions (ORR), they suffer from high temperature and complicated fabrication processes. [4][5][6][7] Therefore, it is of primary importance to fabricate low-cost and readily synthesized support materials for precious metals in fuel cells renewable energy field. Accordingly, recent researches and commercial developments of fuel cells have predominant aims at introducing new class of electrodes fabricated by cost-effective and environmentally-friendly processes.…”
