Abstract

The present work investigates the performance and degradation mechanisms of a Ni-based anode supported Solid Oxides Fuel Cells (SOFC) operating at 800 and 900°C on direct internal reforming of dry and wet natural gas. The catalytic properties of the anode support were first studied to determine safe conditions under which a dry conversion of the methane can occur directly within the fuel cell. A full electrochemical characterization of complete cells followed to preliminarily assess their resistance towards carbon formation when operating on direct dry-reforming. Impedance spectra have been taken every step of continuous operation to monitor the trend over the time of the different polarization contributions.
