A fuel cell stack is provided in which a plurality of single cells each including a membrane electrode assembly are stacked in a stacking direction. The fuel cell stack includes a plurality of electrical insulation members each connected to an outer peripheral portion of a corresponding one of the membrane electrode assemblies. The fuel cell stack further includes a first displacement absorbing member disposed between each insulation member and an adjacent insulation member. L'invention porte sur un assemblage de piles à combustible dans lequel une pluralité de piles individuelles comprenant chacune un ensemble membrane-électrode sont empilées suivant une direction d'empilement. L'assemblage de piles à combustible comprend une pluralité d'éléments d'isolation électrique reliés chacun à une partie périphérique externe d'un élément correspondant des ensembles membrane-électrode. L'assemblage de piles à combustible comprend en outre un premier élément absorbant les déplacements, disposé entre chaque élément d'isolation et un élément d'isolation adjacent.
