“…Therefore, the biogas fuelling these generators must be deeply cleaned. Sasaki et al [132] showed the progressive reduction in cell voltage of a SOFC by 10 ppm v siloxane (D5) in 3%-humidified H 2 at 800 1C, 900 1C and 1000 1C. The Open Circuit Voltage (OCV) dropped from 1 V to below 0.5 V in less than 30 h and degradation was faster at lower operating temperatures.…”

“…The vast literature refers and focusses on systems, which are fed with H 2 S in H 2 -containing fuels. They studied the deactivation mechanisms and materials application Zha et al, 2007;Li T. S. et al, 2009;Li et al, 2010;Hagen, 2009, 2010;Xu et al, 2010;Li and Wang, 2011a,b), summarized in several studies and reviews (Sasaki et al, 2006(Sasaki et al, , 2011Trembly et al, 2006;Gong et al, 2007;Goodenough and Huang, 2007;Sun and Stimming, 2007;Rasmussen and Hagen, 2009;Yang et al, 2010;Cheng et al, 2011;Hagen et al, 2011;Kromp et al, 2012;Hagen, 2013;Wang et al, 2013;Weber et al, 2013;Hauch et al, 2014). The effect of a sulfur-containing fuel is examined on the performance and durability of SOFCs through the variation of several factors, such as the: (i) operating temperature, (ii) applied current/voltage load, (iii) time on stream, (iv) H 2 S concentration and to a lesser extent the concentration of H 2 and H 2 O, and (v) the anodes materials.…”

HIGHLIGHTS• The kinetics of CH 4 steam reforming and partial oxidation are determined by the oxidation rate of CH x adsorbed species • The modification of the Ni/YSZ and Ni/GDC with Au and/or Au-Mo results in differentiated structures of atomically dispersed Au and/or Au-Mo at the surface and the bulk of the Ni particles.• At lean S/C NiAu/YSZ selectively oxidizes electrochemically the catalytically produced H 2 and CO, while NiAu/GDC is selective to the direct partial electrochemical oxidation of CH 4 to CO and H 2.• The modified electrodes show significant tolerance to C formation.• Au-Mo modification enhances the intrinsic sulfur tolerance properties of Ni/GDC.The presented work is a short review of the research attempts from our group with collaborators, during the last 15 years, which had as main objective to study and improve the electrocatalytic performance of Ni-based electrode materials for the CH 4 Internal steam Reforming process (ISR.) in Solid Oxide Fuel Cells (SOFCs). In particular, NiO/YSZ and NiO/GDC anode powders were modified with Au and/or Mo nano-particles via different preparation methods. These efforts resulted in anode materials with high tolerance and improved electrocatalytic activity under both carbon forming and sulfur poisoning conditions. The most important findings are being reviewed and critical findings are being highlighted 50 as to stress the key differences in the electrocatalytic performance between Ni/YSZ and Ni/GDC. The possible effects of Au and/or Mo addition on the physicochemical and strucutral properties of the cermets are thoroughly discussed as well as active functional layers in the form of anode SOFC electrodes.

“…Sasaki et al [42] studied theoretically the reactivity of with H 2 S nickel using thermochemically calculation software, FactSage v5.2 Thermafact Ltd (Montreal, Canada). They analysed stability diagrams of CeHeOeNieS system at 600 and 800 C assuming the H 2 S concentrations of 5 and 100 ppm(v) in the fuel.…”
