“…For instance, the decoration of the Ni‐based anode against coking could be achieved by the addition of a small quantity of another metal on the surface of Ni particles . Among the various metal modifiers, Pd was demonstrated to be a useful promoter to enhance the coking resistance of Ni‐based anodes of SOFC operating on ethanol fuel . Babaei et al.…”

“…Babaei et al. found that the addition of Pd nanoparticles significantly promoted the electrocatalytic activity and coking resistance of Ni‐GDC anode for the electro‐oxidation reaction of methane fuel and particularly of methanol and ethanol fuels . It revealed that, different from what was observed in methane, there was no filament carbon formation in methanol and ethanol fuels, suggesting that the presence of hydroxide groups in the molecular structure of alcohols may facilitate the carbon removal from the anode surface.…”

Solid oxide fuel cells (SOFCs) are the most widely used fuel cells due to their excellent fuel flexibility, high efficiency and low emissions. Although the liquid fuels are easier to handle and transport than hydrogen, their direct use in SOFC leads to serious performance deterioration because of the coke formation on the traditional Ni‐based cermet anodes. In this review, the advances in the development of coking resistant anodes and the new liquid fuels such as oxygenated hydrocarbons to solve the problem of coke formation with Ni‐based anodes are summarized. It is concluded that Ni‐based cermets are still the most promising anode materials and some targeted modifications are needed to improve the coking resistance. Several strategies to improve the coking resistance of Ni‐based anodes are highlighted. The aim of this review is to provide some helpful guidance and potential directions for the future design of anodes for SOFCs utilizing liquid oxygenated hydrocarbon fuels directly.

“…In parallel, it has become evident that addition of metal nanoparticles to either oxide or composite (ceramic and metal, cermet) anodes can substantially enhance catalytic activity. Most such studies again address hydrocarbon utilization, [10][11][12][13] but enhancements are oen observed even for hydrogen electro-oxidation. 14,15 These parallel observations suggest an anode that combines a high surface-area, nanostructured ceria with metal nanoparticle catalysts will maximize active site densities of both types (i.e., both metal catalyzed and oxide catalyzed) and result in extremely high activity.…”

Metal nanoparticles are of significant importance for chemical and electrochemical transformations due to their high surface-to-volume ratio and possible unique catalytic properties. However, the poor thermal stability of nano-sized particles typically limits their use to low temperature conditions (<500 C).Furthermore, for electrocatalytic applications they must be placed in simultaneous contact with percolating ionic and electronic current transport pathways. Broader contextSolid oxide fuel cells (SOFCs) provide unparalleled fuel-to-electric conversion efficiency across power scales, from a few milliwatts to hundreds of megawatts. A key barrier to widespread SOFC deployment has been high cost, in part attributable to the high temperature of operation, typically in the 800-1000 C range.Lower temperature operation, in turn, has been hindered by poor electrocatalysis rates. Here we demonstrate SOFC anodes with unprecedented activity for both hydrogen and methane electro-oxidation at 600 C. The innovation lies in the use of nanostructured ceria in combination with ultra-low loadings (11 mg cm À2 ) of catalytic metals: Pt, Pd, Ni or Co. Despite the nanoscale features, the activity experiences negligible degradation over a continuous measurement period of 120 h. This work sets the stage for the adoption of high efficiency SOFCs for the cost-effective utilization of natural gas in electric power generation.

“…In recent works, these topics appear to be of increasing interest in SOFC research. On one hand there are a number of efforts interested in reducing carbon deposition in fuel cell anodes of various material compositions and different fuels, [41,42,43]. On the other hand research on carbon deposition and anode recirculation often go hand-in-hand, [44,45,46].…”
