を可能とした。The method for manufacturing a cylindrical sintered solid oxide fuel cell according to the present invention is as shown in FIG. 1 when a cylindrical sintered solid oxide fuel cell is manufactured by a sintering method. At the initial stage of the process, an electrolyte sheet (green sheet) 9 before firing is attached to the electrode support tube 2 in a green state and then sintered, and then a film of electrolyte slurry is superposed on the surface of the electrolyte sheet 9. It is possible to apply the densely formed electrolyte membrane 11 as shown in FIG. 3 without variation.

る。That is, the electrolyte membrane obtained by the method of the present invention is a denser electrolyte membrane than the conventional one, as shown in FIG. 3 (B) which is an enlarged view of FIG. 3 (A). This is because the conventional film forming method cannot eliminate the variation that occurs in the dipping step, but in the present invention, the electrolyte sheet 9 is used as the base of the membrane and the electrode support tube 2 is attached and then sintered. This is because, since the thickness of the base is at least uniform, the variation unlike the conventional case does not occur.

なる。Further, as shown in FIG. 3, the minute cracks 10 generated during the sintering of the electrolyte sheet film are formed on the sintered film of the electrolyte sheet 9 in the same manner as in the prior art to form a film with the electrolyte slurry. At this time, since the electrolyte particles enter the minute cracks 10 having a small resistance by being pulled by the suction pump 8 and block the space, as a result, a sufficiently dense electrolyte film 11 having no variation is formed. It becomes possible.

This is different from the conventional manufacturing method in that it is baked after being attached to the electrode support tube 9 in this state.
