Preferred Features: The electrolyte is made from tetragonal zirconia polycrystals, scandium doped cubic stabilized zirconium oxide, lanthanum-strontium-gallium-magnesium oxide having a perovskite structure, gadolinium oxide doped cerium oxide, BiCuVOx or BiErOx. The anode is made from metallic or oxide ion conducting materials or a mixed-conducting material having catalytically active components.",
