Abstract

This work investigates the catalytic properties of different solid oxide fuel cell (SOFC) Ni-based anodestoward the dry reforming of CH4. The analysis is carried out in a tubular quartz micro-reactor. A massspectrometer is used to analyze the outlet gas composition and thus to evaluate the methane conversionrate. Temperature Programmed Oxidation (TPO) experiments were also performed on the anode samplesto calculate the amount of deposited carbon.Ni based anodes differing in term of microstructure, with both yttria stabilized zirconia and gadoliniadoped-ceria, were tested. The investigated catalytic properties were related to the anode microstructureby measuring the specific surface area of the different samples and by means of morphological ob-servations.It is found that the conversion rate of methane is strongly dependent on the specific surface area ofthe anode.
