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