PURPOSE:To obtain a paste type electrolyte body having no deformation and elusion of the electrolyte body, high electrolyte holding ability, good corrosion resistance and long stability by using an electrolyte body prepared by hot press- molding metal oxide fibers whose surfaces are covered with lithium, lithium aluminate fine powder, and electrolyte. CONSTITUTION:Lithium aluminate fine powder is mixed with alumina fibers whose surfaces are covered with lithium, and solvent is added and they are kneaded and dried. 60wt% electrolyte is added to 40wt% above lithium aluminate containing alumina fibers, and they are kneaded and press-molded with a hot press to form a paste type electrolyte body. An air electrode 4 and a fuel electrode 5 are faced with the electrolyte body 3 interposed. An oxidizing gas chamber 6 and a metal current collector 7 are arranged on air electrode side, and a fuel gas chamber 8 and a metal current collector 9 are on fuel electrode side. A molten salt fuel electrode formed by this process provides high performance and power generation for a long time. |
