| Abstract: | In the present work we describe a Solid Oxide Fuel Cell (SOFC) that comprises a Ni/GDC cermet anode, doped with a potentially commercially viable concentration of gold nano-particles. Specifically, gold was applied prior to anode sintering via the deposition–precipitation method. This procedure resulted in a SOFC that allowed carbon tolerant operation at T = 850 °C under fuel rich internal steam reforming of methane, with a stable power density of 0.41 W cm−2 at 810 mV for over 200 h. |
