[Objective] To reduce the amount of water vapor mixed into the fuel, to reduce the interfacial resistance, to improve the cell output voltage, and to reduce the deposition of carbon generated in the fuel electrode as much as possible. [Configuration] The fuel electrode of a fuel cell composed of a dense solid electrolyte, a porous fuel electrode and an air electrode provided on both sides thereof is formed from a cermet of a metal and a CeO 2 -based or ZrO 2 -based electrolyte material. Fine particles of a CeO 2 based electrolyte material to which rare earth elements are added, or fine particles of a ZrO 2 based electrolyte material to which rare earth elements or rare earth elements and TiO 2 are added, and Ni based fine particles And a mixture thereof was added. |
