Abstract

Solid oxide fuel cells (SOFCs) with NiO-ScSZ and Ni_0.9Mg_0.1O-ScSZ-based anodes were operated by directly feeding a fuel mixture of CH₄, CO₂ and N₂ (CH₄ to CO₂ ratio of 3:2). Stable operation under constant current load (200 mA cm^-2) was achieved with a NiO-ScSZ type anode during 200 h operating hours at 900 °C. Less stable operation occurred with a Ni_0.9Mg_0.1O-ScSZ type anode. In the case of SOFC with Ni_0.9Mg_0.1O-ScSZ as the anode, the methane reforming activity was higher than that with NiO-ScSZ. This was explained by change in the microstructure promoting reforming reactions. However, the addition of MgO resulted in degradation of electrochemical performance due to increase in ohmic resistance of the anode material during operation.
