Title (EN) SEAL STRUCTURE OF A FUEL CELL
(FR) STRUCTURE D'ETANCHEITE D'UNE PILE A COMBUSTIBLE
Abstract: front page image
(EN)A seal structure of a fuel cell includes an interrupted back-up disposed at at least one of a connecting gas passage and a connecting coolant passage. The back-up located on one side of a separator and a portion of a seal line located on the other side of the separator are disposed such that the back-up and the portion of the seal line are overlapped with each other in a fuel cell stacking direction. The interrupted back-up may be formed in the seal or in the separator.
(FR)L'invention concerne une structure d'étanchéité d'une pile à combustible, cette structure comprenant un renfort discontinu disposé au niveau d'un passage de gaz de liaison et/ou d'un passage de liquide de refroidissement de liaison. Le renfort situé d'un côté d'un séparateur et une partie d'une ligne d'étanchéité située de l'autre côté du séparateur sont disposés de telle sorte que le renfort et ladite partie se chevauchent dans une direction d'empilement de piles à combustible. Le renfort discontinu peut être formé dans le dispositif d'étanchéité ou dans le séparateur.
