CATHODE FOR MOLTEN CARBONATE FUEL CELL AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: An air electrode for molten carbonate fuel cell is provided to improve performance of a fuel cell while stably operating cells for long term by reducing polarization resistance of an air electrode through a quick oxygen-reduction reaction rate. CONSTITUTION: An air electrode for molten carbonate fuel cell comprises a porous nickel base electrode, and a metal particle coating the electrode. At least a part of the metal particle is attached to the surface of the nickel particle. The metal particle is one or more selected from a group consisting of silver, gold, copper, platinum, and cobalt. A manufacturing method of the air electrode comprises: a step of preparing coating liquid by dispersing the metal particle into a solvent; and a step of spreading the metal particle-coated liquid on the surface of the porous nickel base electrode.
