CA 2657102

Disclosed herein is a fuel cell assembly that arranges a plurality of individual fuel cells into an array. The fuel cells are set into openings formed in a frame. The openings are arranged into the array, such as in columns and rows. A rear cover is sealingly attached to the frame, thereby defining a chamber between the frame and a base of the rear cover, where the chamber serves as a manifold. Optional supports extend from the base to the fuel cells. The void forms a fluid manifold for dispersing fuel for the fuel cells from a fuel reservoir to the fuel cells. Alternatively, the rear cover separates the interstitial space between the rear cover and the frame into compartments, which are fluidly interconnected by channels. The array may also include a functional element electrically connected to the fuel cells configured to transfer power an electronic device.

L'invention concerne un ensemble de piles à combustible qui dispose en un ensemble une pluralité de piles à combustible individuelles. Les piles à combustible sont installées dans des ouvertures formées dans un cadre. Les ouvertures sont disposées dans l'ensemble, par exemple en colonnes et en rangées. Un couvercle arrière est attaché de manière étanche au cadre, définissant ainsi une chambre entre le cadre et une base du couvercle arrière, la chambre servant de collecteur. Des supports facultatifs s'étendent de la base aux piles à combustible. Le vide forme un collecteur de fluide permettant de distribuer un combustible d'un réservoir de combustible aux piles à combustible. En variante, le couvercle arrière sépare l'espace interstitiel entre le couvercle arrière et le cadre en compartiments, raccordés fluidement par des canaux. L'ensemble peut également comprendre un élément fonctionnel connecté électriquement aux piles à combustible, lesquelles sont conçues pour transférer de l'électricité à un dispositif électronique.
