Fuel cell stack fastening device
专利汇可以提供Fuel cell stack fastening device专利检索，专利查询，专利分析的服务。并且PURPOSE:To decrease height and weight of a cell stack by extruding fastening pieces from the upper and lower end plates of a cell stack and compressing both fastening plates with nuts threadedly engaging to a coupling rod through the coupling rod and spring. CONSTITUTION:Fastening pieces 9 are extruded from each corner of the upper and lower end plates of a cell stack, and a blind hole is installed in each fastening piece. A belleville 6 and a washer 7 are mounted at each end of a coupling rod 5 extruded in the blind hole 11 and a nut 8 is fastened to elastically compress a cell stack 1. A removable cover 13 is arranged so that the inside of the blind hole 11 are not seen. A window 14 is installed in the side wall of the upper blind hole 10 to turn the nut 8 from the outside and the compression degree of the cell stack is suitably adjusted. Height and weight of the cell stack are decreased by eliminating the installation of additional fastening pieces and washers on the end plate.，下面是Fuel cell stack fastening device专利的具体信息内容。
