Abstract

PURPOSE:To unify fastening force in a airtight structure formed between manifolds and a stacked cell by fastening with a fastening band by inserting a fastening wedge between manifolds. CONSTITUTION:A stacked cell 1, a manifold 4, and a manifold 4' are temporarily fastened with a fastening band 9 combined with a pin 10, a fastening bolt 11, and a spring 12 through a gasket 5. After positioning, a fastening wedge 6 which is also used to prevent the movement of manifold is inserted between the manifold 4 and the manifold 4', and the cell and manifolds are fastened with the fastening band 9, pin 10, fastening bolt 11, and spring 12. Thereby, fastening force in airtight structure formed between manifolds and the stacked cell is unified.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は燃料電池に係り、特に、マニホールドと積層電
池間の気密構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a fuel cell, and particularly to an airtight structure between a manifold and a stacked battery.

〔発明の背景〕[Background of the invention]

燃料電池はガスの給排気により反応してエネルギを発生
するため、積層電池とマニホールド間よりの漏れを完全
に遮断する必要がある。Since fuel cells generate energy by reacting with gas supply and exhaust, it is necessary to completely block leakage between the stacked battery and the manifold.

漏れる欠点があった。In the conventional structure, as shown in Fig. 1, the stacked battery 1 and the manifolds 4 and 4' are tightened with a tightening band 9 via a gasket 5, so the manifold 4 and the manifold 1 are in a straight line, and the tightening force is different from each other. There was a drawback that the manifolds 4, 4' did not work uniformly and gas leaked from between the stacked battery 1 and the manifolds 4, 4'.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、締付力を均一化したマニホールドと積
層電池間の気密構造を提供するにある。An object of the present invention is to provide an airtight structure between a manifold and a laminated battery in which the tightening force is made uniform.

After temporarily tightening and positioning the combination of tightening bolts 11 and springs 12, insert the manifold movement prevention/tightening wedge 6 between the manifold 4 and manifold 4' as shown in Figures 4 and 5. By inserting and tightening with the tightening band 9, pin 10, tightening bolt 11, and spring 12, the stacked battery 1, manifold 4, and manifold 4' are integrated, so gas leakage can be prevented. In the manifold movement prevention and tightening wedge 6, the groove 7 is used for inserting the stacked battery tightening rod 3, and the groove 8 is used for guiding the tightening band 9.
