CA 2549555
(1) In a fuel cell stack structure wherein a stack is formed by stacking cells each of which is formed by sandwiching an MEA between two separators, an adhesive layer 33a is provided between the two separators sandwiching the MEA, without a constant thickness structure or pseudo constant thickness structure provided between the separators. (2) An adhesive layer 33b is provided between adjacent cells, without a bead gasket provided therebetween. (3) The adhesive layers 33a, 33b have a Young's modulus of 100 MPa or less.
(1) L'invention concerne une structure d'empilement de piles à combustible, obtenue par l'empilement de piles formées chacune par la mise en sandwich d'un MEA entre deux séparateurs ; une couche adhésive (33a), prévue entre les deux séparateurs prenant en sandwich le MEA, rend superflue toute structure d'épaisseur constante ou pseudo constante entre lesdits séparateurs. (2) Une couche adhésive (33b), prévue entre des piles adjacentes, rend superflue toute garniture d'étanchéité entre celles-ci. (3) Les couches adhésives (33a, 33b) présentent un module de Young égal ou inférieur à 100 MPa.
