Abstract: PURPOSE: Electrolyte membrane for solid oxide fuel cell is provided not to cause the electrical short even in manufacturing electrolyte in thickness of hundreds nanometers, and to work in lower temperature than the existing solid fuel cell. CONSTITUTION: Electrolyte membrane for solid oxide fuel cell comprises at least two deposition layers. The average crystal grain size of those two or more than two deposition layers above are 10-100nm each, and each average size of grain is different. Among those deposition layers above, the size of the deposition layer adjacent to anode is 5-50nm, the average size of grain of the deposition layer adjacent to cathode is 50-100nm. The average size difference of grain of the deposition layer adjacent to anode and the deposition layer adjacent to anode is 10-95nm.
