PROBLEM TO BE SOLVED: To provide unit cells of cylindrical solid electrolyte fuel cell and offer their manufacturing method, whereb is possible to suppress gas leakage in the inter-connector part even though inter-connector is of a type to admit easy permeation of gas. SOLUTION: Slurry of the same substance as a base pipe 11 is adsorbed to a predetermined place(s) on the peripheral surface of the base pipe 11 made of a porous material, and the pipe 11 is subjected to a provisional baking process, and thereby a low density layer 11a admitting gas permeation is formed in the above-mentioned place(s). Slurry constituting a fuel gas electrode 12 is applied to that peripheral surface portion of the pipe 11 excluding the specified place(s) and also a slurry constituting an electrolyte 13 is applied, and a slurry constituting an inter-connector 16 is applied to the predetermined place(s) on the peripheral surface of the pipe 11, followed by backing of the pipe 11, and a slurry constituting an oxidator gas electrode 14 is applied to the electrolyte 13 and left for a backing process, and thus cells are accomplished where a dense layer 11a is provided on the peripheral surface of the pipe 11 in contact with the inter-connector 16. |
