摘要：
This invention provides an electrolyte sheet for solid oxide fuel cells, characterized in: being formed by a doctor blade method or an extrusion molding method; being a scandia partially stabilized zirconia sheet, wherein 4 mol % to 6 mol % scandia is doped in a solid zirconia; a crystal structure thereof has a polycrystalline structure having a main body of tetragonal and including monoclinic phase, wherein a ratio of monoclinic phase (M), calculated by below described formula (1) from a diffraction peak intensity using X-ray diffraction, is 1% to 80%; and a Weibull modulus (m) thereof is not less than 10: a ratio of monoclinic phase(M:%)=[{monoclinic(1,1,1)+monoclinic(−1,1,1)}/{tetragonal and cubic(1,1,1)+monoclinic(1,1,1)+monoclinic(−1,1,1)}]×100 (1).
