Abstract[English]
The invention is related to a fuel cell stack (100) for a fuel cell system (200) comprising multiple fuel cells (110) stacked upon each other along a stack direction (SD), wherein the fuel cells (110) are enclosed by end plates (10), wherein the end plates (10) are mechanically connected with each other by connection straps (120) extending along the stack direction (SD) on different sides of the fuel cells (110), wherein the connection straps (120) consist of fibre reinforced matrix material and are wound around connection lugs (122) connected to connection pins (60) of the end plates (10), wherein the end plates (10) are electrically insulating and the contact area between the end plates (10) and the fuel cells (110) is free from an insulating plate.[French]
L'invention concerne un empilement de piles à combustible (100) pour un système de pile à combustible (200) comprenant de multiples piles à combustible (110) empilées les unes sur les autres le long d'une direction d'empilement (SD), les piles à combustible (110) étant enfermées par des plaques d'extrémité (10), les plaques d'extrémité (10) étant reliées mécaniquement les unes aux autres par des sangles de liaison (120) s'étendant le long de la direction d'empilement (SD) sur différents côtés des piles à combustible (110), les sangles de liaison (120) étant constituées d'un matériau de matrice renforcé par des fibres et étant enroulées autour de pattes de liaison (122) reliées à des broches de liaison (60) des plaques d'extrémité (10), les plaques d'extrémité (10) étant électriquement isolantes et la zone de contact entre les plaques d'extrémité (10) et les piles à combustible (110) étant dépourvue d'une plaque isolante.
