Accordingly, the sealing member can be formed as a sealant layer extending along the circumference of the first mounting portion 21 and the second mounting portion 31 .

[0060] In other words, the air duct 60 can be a ceramic tube. After the symmetrical solid oxide fuel cell 200 is laid between the first end plate 20 and the third end plate 30, ceramic glue is applied to seal the connection between the air duct 60 and the first end plate 20 and the matching position between the symmetrical solid oxide fuel cell 200 and the first mounting portion 21 and the second mounting portion 31 to ensure the seal between the air inlet 23 and the air outlet 24.
