Zusammenfassung:To provide a solid oxide fuel cell with improved durability while obtaining sufficient electricity generating performance. The present invention is a method for manufacturing solid oxide fuel cells (16) in which electricity generating elements (16a) are connected by an interconnector (102), including: a support body forming step (S1); surface deposition steps (S4, S9) for forming in sequence a first and second functional layer on a porous support body; an outermost layer deposition step (S13) for forming an outermost functional layer (101) in which slurry in liquid droplet form is continuously jetted to form dots, and an outermost functional layer is formed by the agglomeration of dots to be thicker than a first functional layer (98); and a sintering step (S14) for sintering functional layers; wherein in the outermost functional layer, traces of agglomerated dots remain and ring-shaped cracks surrounding each dot trace are formed by the sintering process.
