に開示きれている。(b) Conventional technology Without directly attaching a manifold to the battery stack, frames that are in contact with each circumferential surface of the stack are elastically connected via a sealing material, and the stack is tightened from the outer periphery. A method of attaching a manifold through two sealing materials is disclosed in Japanese Patent Laid-Open No. 5S-197-3Y9 filed by the present applicant.

。With this method, the mounting collar of the manifold can be bolted to the frame around the entire circumference, and the sealing performance between the two is significantly improved. However, if the manifolds for each reaction gas are installed parallel to the frame Although both sides of the body are tightened by the connecting members, the intermediate partition of the frame cannot be tightened, so the shielding and sealing properties between the intermediate partition and the battery stack surface are insufficient, especially at the center of the height. There was a risk that a small gap would be created due to insufficient pressure, and there was a risk of cross leakage of both gases. In order to prevent this, the applicant of the present application proposed various methods, but none of them could be said to be perfect.
