Abstract

See full text

An electrolyte sheet for solid oxide fuel batteries with mechanical strength characteristics is proposed. These characteristics may include a high and stable average value of strength, Weibull coefficient, and a high adhesion to an electrode formed on a surface thereof and hence inhibits the electrode from interfacial separation from the electrolyte sheet. The electrolyte sheet for solid oxide fuel batteries is characterized by having a plurality of concaves and/or convexes on at least one surface thereof, the concaves and convexes having base faces which are circular or elliptic or are a rounded polygon in which the vertexes have a curved shape with a curvature radius of 0.1 μm or larger and/or the concaves and convexes having a three-dimensional shape which is semispherical or semiellipsoidal or is a polyhedron in which the vertexes and the edges have a curved cross-sectional shape having a curvature radius of 0.1 μm or larger.
