The present invention is a method of manufacturing fuel cells (16), including a support body-forming step (S1) for forming a porous support body (97), a film deposition step for laminating functional layers constituting electricity generating elements on a support body; and a sintering step (S14, S16) for sintering the support body on which functional layers are formed; whereby the film deposition step includes surface deposition steps (S5, S11), in which a masking layer is formed in parts not requiring film deposition, and electricity generating elements first functional layers are simultaneously formed, and a dot deposition step (S15), in which slurry dots are formed by placing a slurry into a liquid droplet state and jetting it, and a second functional layer is formed by the agglomeration of these dots.
摘要:
A solid oxide fuel cell scatters MgO over a grain boundary of an LSGM which is a solid electrolyte layer. Ni components that diffuse from a fuel electrode formed on the other side of an LDC from the LSGM are trapped by the scattered MgO particles and are suppressed from diffusing towards an air electrode in the electrolyte layer.
