PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid oxide fuel battery cell, by which a roughly uniform film thickness can be achieved even in the case of a porous supporting body with low dimensional accuracy.SOLUTION: A method for manufacturing a solid oxide fuel battery cell (16) in which power-generation elements are connected by interconnectors comprises: a support body formation step; a masking formation step for forming, on parts where no film needs to be formed, masking layers (104) in position relative to a jig (146) supporting a porous supporting body (97); a plane film formation step for forming first functional layers (98) differing from the porous supporting body in color on parts where the masking layer is not located on the porous supporting body by putting a slurry into contact from above the masking layers; a locating step for taking an image of the porous supporting body, and locating the position of an edge of the functional layer by image analysis; and a film formation step for forming interconnectors (102a) in position relative to the located position; and a sintering step for sintering the functional layers by heating.SELECTED DRAWING: Figure 12 【課題】多孔質支持体の寸法精度が低い場合でも概ね均一な膜厚を得ることができる固体酸化物形燃料電池セルの製造方法を提供する。【解決手段】本発明は、複数の発電素子をインターコネクタにより接続した固体酸化物形燃料電池セル(16)の製造方法であって、支持体形成工程と、成膜が不要な部分に多孔質支持体(97)を支持している治具(146)を基準として、マスキング層(104)を形成するマスキング形成工程と、多孔質支持体上に、マスキング層の上からスラリーを接触させることにより、マスキング層のない部分に多孔質支持体とは色が異なる第１の機能層(98)を形成する面成膜工程と、多孔質支持体を撮像し、画像解析により機能層の縁部の位置を特定する位置出し工程と、これにより特定された位置を基準として、インターコネクタ(102a)を形成する成膜工程と、機能層を加熱し、焼成する焼成工程と、を有することを特徴としている。【選択図】図１２
