A device for assembling a banded fuel cell stack with at least one custom-fit band comprises a frame, a base to support the stack while assembling, a press plate that is movable toward and away from the base to compress the stack under a constant force, band folding means to fold the band around the compressed stack such that the ends of the band overlap and welding means for welding the overlapped ends of the band. A method for assembling the banded fuel cell stack with at least one custom-fit band is also described. The device can be used to fit a plurality of compression bands around the assembled stack.

L'invention concerne un empilement de cellules de pile à combustible rubané, comportant au moins une bande ajustable selon l'usage, qui comprend un cadre, une base pour soutenir l'empilement pendant le montage, une plaque de compression pouvant être déplacée en direction de la base et loin de la base, afin de comprimer l'empilement sous une force constante, des moyens de pliage de bande, pour enrouler la bande autour de l'empilement comprimé, de sorte que les extrémités de ladite bande se chevauchent, ainsi que des moyens de soudage pour souder les extrémités superposées de la bande. L'invention concerne un procédé permettant d'assembler l'empilement de cellules de pile à combustible rubané avec au moins une bande ajustable selon l'usage. Le dispositif peut s'utiliser pour ajuster une pluralité de bandes de compression autour de l'empilement assemblé.
