“…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.

“…This is the first report using methanogenic bacteria in the shrimp pond sludge for the digestion of bagasse and molasses. Furthermore, the produced biogas was used as fuel for the test on SOFC in which direct internal reforming (DIR) technology (Staniforth and Kendall, 1998;Yentekakis, 2006;Janardhanan et al, 2007;Shiratori et al, 2008;Lanzini and Leone, 2010;Leone et al, 2012;Papadam et al, 2012;Lanzini et al, 2013) using a paper-structured catalyst (PSC; Fukahori et al, 2006;Shiratori et al, 2015;Shiratori and Sakamoto, 2016) was applied to achieve SOFC power generation by direct feed of the biogas without any fuel processing.…”

Fuel-flexible solid oxide fuel cell (SOFC) technologies are presently under study in a Vietnam-Japan international joint research project. The purpose of this project is to develop and demonstrate an SOFC-incorporated energy circulation system for the sustainable development of the Mekong Delta region. Lab-scale methane fermentation experiments in this study with a mixture of biomass feedstock collected in the Mekong Delta (shrimp pond sludge, bagasse, and molasses from sugar production) recorded biogas production yield over 400 L kgVS −1 with H 2 S concentration below 50 ppm level. This real biogas was directly supplied to an SOFC without any fuel processing such as desulfurization, methane enrichment and pre-reforming, and stable power generation was achieved by applying paper-structured catalyst (PSC) technology.

Solid Oxide Fuel Cell (SOFC) is typically operated at high temperature. Both electricity and heat are generated during operation. Therefore, SOFC can be efficiently designed to integrate the endothermic reformer with the cell for optimizing heat utilization, as called autothermal operation. However, the mismatch between rate of exothermic electrochemical reaction and endothermic reforming reaction is easily resulted in material cracking of that integrated structure. In order to overcome the thermal mismatch limitation, various approaches for autothermal SOFC configurations have been widely developed; these configurations can be classified into 2 main groups including direct internal reforming (as called DIR-SOFC) and indirect internal reforming (as called IIR-SOFC) operations. This review focuses on the technological progress of these various configurations. In detail, the thermal behavior inside each autothermal SOFC configuration is explored. The effect of different primary hydrocarbon fuels on temperature distribution in the autothermal SOFC structures is also indicted. In addition, the advantage and disadvantage on thermal stress reduction of each configuration are also discussed. The historical of this development would advantage for further system modification and scale up to desired power output
