“…Therefore, the oxygen ions from the bulk SDC can effectively react with CO or quickly oxidize some carbon formed in the anode layer. Yun et al suggested that with the SDC available at the anode, carbon accumulation can be reduced by its subsequent oxidation (C þ O 2À / CO þ 2e À ) by oxygen ions within the anode [21]. Thus, the SDC in the Ni-SDC anode cermet may have promoted carbon removal within the anode and reduce the risk of cell failure due to carbon deposition.…”

“…The typical NiO-YSZ anode with excellent catalytic properties and good electrical conductivity is deactivated during operation because of its sensitivity to carbon build-up from in complete oxidation of methane, which can be improved through the substitute of ceria-based oxidation catalysts (e.g. SDC) [7][8][9][10][11][12]. Recently, some new microstructure for NiO-SDC anodes were investigated as alternative anode materials for direct use with methane fuels, such as surface modification of NiO-SDC anode by impregnation [9][10][11].…”

Recently, some new microstructure for NiO-SDC anodes were investigated as alternative anode materials for direct use with methane fuels, such as surface modification of NiO-SDC anode by impregnation [9][10][11]. This results have indicated that the adjustment of NiO-SDC anodes are very effective in suppressing catalytic carbon formation by blocking methane from approaching the nickel, which is catalytically active towards methane pyrolysis [13][14][15][16].…”

A robust NiO-Sm0.2Ce0.8O1.9 anode for direct-methane solid oxide fuel cell, Materials Research Bulletin http://dx.doi.org/10. 1016/j.materresbull.2015.06.042 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript.

Graphical abstractHighlights  Robust NiO-SDC anode is synthesized by co-assembly for direct-methane SOFC. The cell performance was improved by 40%-45% with the new NiO-SDC anode. No significant degradation of the cell performance was observed after 60 hours. The double-pore NiO-SDC anode with higher TPB is promising for SOFC. AbstractIn order to directly use methane without a reforming process, NiO-Sm 0.2 Ce 0.8 O 1.9 (NiO-SDC) nanocomposite anode are successfully synthesized via a one-pot, surfactant-assisted co-assembly approach for direct-methane solid oxide fuel cells.Both NiO with cubic phase and SDC with fluorite phase are obtained at 550°C. Both 2 NiO nanoparticles and SDC nanoparticles are highly monodispersed in size with nearly spherical shapes. Based on the as-synthesized NiO-SDC, two kinds of single cells with different micro/macro-porous structure are successfully fabricated. As a result, the cell performance was improved by 40%-45% with the new double-pore NiO-SDC anode relative to the cell performance with the conventional NiO-SDC anode due to a wider triple-phase-boundary (TPB) area. In addition, no significant degradation of the cell performance was observed after 60 hours, which means an increasing of long term stability. Therefore, the as-synthesized NiO-SDC nanocomposite is a promising anode for direct-methane solid oxide fuel cells.
