PROBLEM TO BE SOLVED: To solve the problem that the bonding strength between an air pole, the electrolyte and a collector is not enough and that the polarization resistance and the contact resistance of the interface is increased so as to hinder the power generating performance of a fuel cell itself in co-sintering. SOLUTION: This manufacturing method of a cylindrical fuel cell is provided with a process for manufacturing a cylindrical molding as an air layer 1, which is made of the air pole forming powder, a process for calcining the cylindrical molding at 900-1400 deg.C, a process for winding a sheet-shaped molding as a solid electrolyte layer 2, which is made of the solid electrolyte forming powder, and a sheet-shaped collector layer 4 as a collector layer 4, which is made of the collector forming powder, around the surface of the calcined cylindrical molding for lamination. A process for co-sintering the cylindrical laminated body at 1300-1700 deg.C in the oxidizing atmosphere is provided. |
