A FUEL CELL WITH BONDING LAYER OF FUNCTIONALLY GRADIENT MATERIAL AND THE METHOD FOR MANUFACTURING A FUEL CELL WITH BONDING LAYER OF FUNCTIONALLY GRADIENT MATERIAL

摘要

PURPOSE: A fuel cell is provided to improve fuel supply efficiency by using an adhesive consisting of a mixture of Ni/YSZ and metal in order to support a unit cell by a metal plate without using an adhesive like slurry. CONSTITUTION: A fuel cell using a bonding layer of functionally gradient material comprises a metallic plate(10), a fuel electrode(31), and a bonding layer(20) bonding the metallic plate and the fuel electrode. The bonding layer is a functionally gradient material consisting of a metal material, and a material forming the fuel electrode. The functionally gradient material has higher content of the metal material toward the metal plate. The metal material comprises Fe. The material forming the fuel electrode is Ni/YSZ. Content of the metal material in the functionally gradient material is reduced from the metal plate toward the fuel electrode from 80 weight% to 20 weight%.
