ELECTRODE FOR SOLID-OXIDE FUEL CELL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide an electrode and an electrode/electrolyte layered product for a solid-oxide type fuel cell, having remarkably increased three-phase boundary face lengths and being less subjected to thermal distorsion. SOLUTION: This electrode is made up by depositing particles 2 made of an electron-conductive material and/or an oxide ion mixed conductive material on surfaces of a skeleton 1 made up of a sintered porous body of three- dimensional network structure made of an oxide ion conductive material and/or an oxide ion mixed conductive material. This electrode is manufactured by forming a foamed sheet by sheet-molding from water slurry mixed with a water- insoluble organic solvent as a foaming agent, forming the skeleton 1 by sintering the foamed sheet, impregnating the skeleton with a slurry containing the particles 2, and joining the particles to each other by sintering them.
