For the solid‐oxide fuel cells (SOFCs), nickel–yttrium‐stabilized zirconia (Ni–YSZ) cermet anodes operating with complex liquid hydrocarbon fuels display severe carbon formation on the Ni surface and sulfur poisoning. In this present study, we fabricate molybdenum dioxide (MoO 2 )‐based anodes with an optimum microporous structure that leads to a maximum power density over 3 W cm −2 at 750 °C under the direct feeding of n ‐dodecane fuel mixture. The cell resisted the carbon (coke) formation for over 24 h of continuous cell testing and was also resistant to deactivation with 500 ppm of sulfur in the fuel stream.
