SOLID ELECTROLYTIC PLATE IN FLAT SOLID ELECTROLYTIC FUEL BATTERY AND FLAT SOLID ELECTROLYTIC FUEL BATTERY USING THE PLATE

摘要

PROBLEM TO BE SOLVED: To form a porous layer being rigid and always of same quality on the surface of a solid electrolytic plate. SOLUTION: When this fuel battery forms a cathode on one side and an anode on the other side with a solid electrolytic plate being sandwiched, a solid electrolytic plate 1 is made of a solid electrolytic layer 10 and a porous layer 11 formed with the same material as this layer. Here, the size of the pore of the porous layer 11 is formed by 0.01 to 50μm and the volume rate occupied in the porous layer 11 is formed by 10 to 80%.
