Neofytidis, M. Athanasiou, S. Neophytides, D. Niakolas] The present work refers to the short communication of a first series of results on how Au and/or Mo addition can affect the stability of modified Ni/GDC anodes for the reaction of internal CH4 steam reforming, in the presence of H2S. Specifically, it is shown that Ni/GDC is stable in the presence of 10ppm H2S, but only in the case where 100 vol% of H2 is the anode feed. In the case where CH4 and H2O (diluted in helium carrier gas) comprise the anode feed, then at ratios equal to S/C=2 or S/C=0.13 the performance of Ni/GDC shows severe degradation, while the Au-Mo-Ni/GDC anode has the best and most stable electrocatalytic behavior. Finally, there is a first attempt to investigate the effect of the electrocatalyst's loading on sulfur tolerance.
