CATHODE MATERIAL FOR FUEL CELL, AND CATHODE FOR FUEL CELL AND SOLID OXIDE FUEL CELL INCLUDING THE MATERIAL

摘要

PURPOSE: A positive electrode material for a fuel cell is provided to maintain low electrode resistance at a low temperature of 800°C or less by reducing polarization resistance of a positive electrode in a solid oxide fuel cell. CONSTITUTION: A positive electrode material for a fuel cell comprises a first metal oxide which has a perovskite structure, and a second metal oxide with a spinel structure. The comprised amount of the first metal oxide and the second metal oxide are 60-99 weight% and 1-40 weight%, respectively. A positive electrode for a fuel cell comprises the positive electrode material. A solid oxide fuel cell comprises a positive electrode which comprises the positive electrode material, a negative electrode which is arranged to face with the positive electrode, and a solid oxide electrolyte arranged between the positive electrode and negative electrode.
