METHOD FOR MANUFACTURING A UNIT CELL OF A SOLID OXIDE FUEL CELL

摘要

The present invention relates to a method for manufacturing unit cells of a solid oxide fuel cell through a process of attaching a fuel electrode reaction layer/electrolyte layer film assembly, manufactured using a tape casting method, onto a fuel electrode support (sintered body) which consists of the unit cells of the solid oxide fuel cell and which is manufactured using a tape casting method, a pressure method, a discharge plasma method, or the like. The method for manufacturing the unit cells of the solid oxide fuel cell comprises the steps of: forming a pre-sintered body of the fuel electrode support; manufacturing a fuel electrode reaction layer sheet; manufacturing an electrolyte layer sheet; manufacturing a film assembly by stacking, into layers, the fuel electrode reaction layer sheet and the electrolyte layer sheet; providing a binder to the pre-sintered body; combining the film assembly with the pre-sintered body provided with the binder; laminating the combined body of the pre-sintered body and the film assembly; co-sintering the laminated combined body; forming an air electrode layer on the electrolyte layer in the co-sintered body; and sintering the resultant structure.
