Patent

CA 2654503

A fuel cell 10 is provided with a cell laminated body 22 in which a plurality of cells 21 are laminated, an end plate 12 arranged outside the cell laminated body 22 in a laminating direction; and a spring module 23 which is arranged between the cell laminated body 22 and the end plate 12 so as to adjust a compressive load to the cell laminated body 22. The spring module 23 is provided with coil springs 53 which are arranged between an upper plate 51 and a lower plate 52 so as to separate the upper plate 51 and the lower plate 52 from each other by an elastic force. The spring module 23 is provided with a plurality of load display sections 61 having display shafts 62 which are fixed to the lower plate 52, inserted into through holes 63 of the upper plate 51 and protrude from the outer surface of the upper plate 51 on an end plate 12 side.

L'invention concerne une batterie à combustible (10) qui comporte un corps stratifié de cellule (22) formé par stratification d'une pluralité de cellules (21) ; une plaque d'extrémité (12) disposée à l'extérieur du corps stratifié de cellule (22) dans la direction de stratification ; et un module de ressort (23), qui est disposé entre le corps stratifié de cellule (22) et la plaque d'extrémité (12) et ajuste une charge de compression au corps stratifié de cellule (22). Le module de ressort (23) comporte un ressort hélicoïdal (53), qui est disposé entre une plaque supérieure (51) et une plaque inférieure (52) et sépare la plaque supérieure (51) de la plaque inférieure (52) l'une de l'autre par une force élastique. Le module de ressort (23) comporte une pluralité de sections d'affichage de charge (61) ayant des arbres d'affichage (62) qui sont fixés à la plaque inférieure (52), introduits à travers un trou traversant (63) de la plaque supérieure (51) et font saillie à l'extérieur de la plaque d'extrémité (12) de la plaque supérieure (51).
