The present invention relates to a fuel-cell cell production method, and the present invention comprises: a step of forming a first electrode layer having a dense structure by using an oxide; a step of forming an electrolyte layer on the first electrode layer; a step of reducing the first electrode layer so as to make same porous; and a step of forming a second electrode layer on the electrolyte layer. When the present invention is employed, there is the advantage that a porous electrode can be produced by forming a thin-film electrolyte layer on the flat surface of the first electrode layer having a dense structure without pores, such that pinholes are prevented from being formed in the thin-film electrolyte layer, and by reducing the first electrode layer by means of a hydrogen atmosphere. |
