Abstract
A solid state fuel cell for oxidation of CH.sub.4 includes a solid state electrolyte that is preferably formed by YSZ (yttrium stabilized zirconium oxide). A surfactive metal oxide is applied onto the electrolyte followed by application of a thin layer of CeO.sub.2 -based ceramics serving as an anode. If desired, MgO can be added in order to improve the volume stability.
