PURPOSE:To improve the performance of the electrolytic cells of a high temperature electrolysis device and a high temperature solid electrolytic fuel device, and to improve the durability of a solid electrolyte itself by using electrolyte for which mixed conductivity is given to the surface of a negative electrode. CONSTITUTION:A solid electrolyte 1 is YSZ, and a surface active agent is added to a particle of 0.5mum to form a slurry, which is placed on a Teflon sheet, and after the slurry is dried naturally, it is backed in the atmosphere. Materials La(NO3)3.6H2O and Ce(NO3)3.6H2O are mixed together at the weight ratio of 1 to 3, to which water is added by 30% by weight ratio and a solution is provided. This solution is applied to one surface of the VSZ plate 1 and is baked to form a mixed conductivity thin film 4. A slurry for which 60wt.% of NiO and 40wt.% of YSZ are mixed together is screen-printed as a negative electrode on the thin film 4. A material LaMnO3 is provided in the same manner to provide a positive electrode. This electrode is baked to form a cell. |
