PROBLEM TO BE SOLVED : To reduce a steam amount mixed into a fuel, improve a cell output voltage by reducing interface resistance, and reduce deposition of carbon formed in a fuel electrode to the utmost. SOLUTION : The fuel cell is constituted of a dense solid electrolyte, and a porous fuel electrode and a porous air electrode formed on both surfaces of the electrolyte. A mixed body of fine particles of the CeO2 series electrolyte materials into which a rare-earth element is added or fine particles of ZrO2 series electrolyte materials into which the rare-earth element or the rare-earth elements plus TiO2 is added and Ni series micro-particles is added to the surface of particles constituting the skeleton of a porous body of the fuel electrode which is composed of a cermet of metal and CeO2 series or ZrO2 series electrolyte materials.
