  • DEVICE FOR ASSEMBLING A BANDED FUEL CELL STACK
    Publication number: 20080271311
    Abstract: 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.
