“…No obvious coke formation was found on the surface of the composite anode after operating the SOFC with glycerol fuel. Similarly, this anode was also used in syngas or dry methanol fueled SOFCs achieving high power outputs and no significant coke formation . This study may bring a new route to prepare ultrafine metal nanoparticles by using perovskite oxides with K 2 NiF 4 ‐type structures as the intermediates.…”

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.

“…However, also naphthalene and benzene are used. Only few works can be found with primary tar (eg, methanol, ethanol, acetic acid, and hydroxyacetone), and they are mostly focused on direct utilization and not on primary tar as biosyngas contaminants . These compounds are called tar despite they generally have a molecular weight lower than that of benzene.…”

Integrated biomass gasifier solid oxide fuel cell systems are an alternative to fossil‐fuel‐based combined heat and power generators. However, biosyngas contaminants represent a bottleneck for small‐scale systems. In this work, we present the results of experiments on the effects of H2S, HCl, and acetic acid as model primary tar on Ni‐GDC SOFC. First, the effects of 17‐128 g/Nm3 dry basis acetic acid were studied. On a second cell, 0.8 and 1.3 ppm(v) H2S were added to the simulated biosyngas anode flow. After a full recovery, the cell was exposed to 42 g/Nm3 acetic acid and 0.8 ppm(v) H2S. On a third cell, 3.4, 20, and 50 ppm(v) HCl were tested and, after a recovery period, 42 g/Nm3 acetic acid and HCl were added. Even 0.8 ppm(v) H2S caused an immediate voltage drop. H2S affected CH4 reforming and water‐gas shift reaction. Differently, even 50 ppm(v) HCl appeared not to significantly affect these reactions. Acetic acid increased the cell voltage but caused carbon deposition at the cell inlet. The voltage increase seemed not to be affected by H2S or HCl, and no acetic acid was measured at the cell outlet, indicating that these contaminants do not affect the primary tar conversion.

“…Ceramic anodes such as La 4 Sr nÀ4 Ti n O 3nþ2 were also investigated for power generation with internal reforming of hydrocarbon fuels [13]. Several researchers tried direct utilization of hydrocarbon fuels such as methanol [14,15], ethanol [16,17], propane [18,19], n-butane [20e22], n-decane [23], n-dodecane [24], toluene [25], biogas [26] and so on in SOFCs. However, it is insufficient to investigate the O 2À ionic conductors such as zirconia and ceria in an anode when the goal is to improve the durability against the carbon deposition in the heavy hydrocarbon fuels.…”
