The present disclosure provides a stable ceramic anode for a solid oxide fuel cell (SOFC) and a method for producing and using the same. In particular, anodes for solid oxide fuel cells disclosed herein can be operated at a significantly lower temperature than conventional SOFCs, and allow thermal and anode gas cycling under transient conditions. More significantly, anodes described in the present disclosure have a significantly higher long-term operability compared to a similar anode having a higher amount of electrocatalyst. In one particular embodiment, the stable ceramic anodes comprise (i) strontium-iron-cobalt-molybdenum oxide (SFCM) material; (ii) a first ion-conductor composition comprising an oxide of cerium or cerium that is doped with a rare-earth metal; and (iii) nanoparticles of an electrocatalyst comprising (a) a second ion-conductor and (b) nickel, a nickel alloy, or a combination thereof. The amount of electrocatalyst in said stable ceramic anode is less than 10 wt %.
