ABSTRACT:
A cartridge and a method for handling thin film membranes using a cartridge are disclosed. The cartridge may be used to handle any thin-film material, but is particularly useful in handling the thin membrane materials used in fabricating Membrane Electrode Assemblies (MEA) for fuel cells. In one aspect, the cartridge includes cavities positioned at opposite ends of a frame. The cavities and associated mounting arrangements are adapted to accept spools for dispensing membrane material and drawing it across the frame. The cartridge also includes a removable cover having an aperture through which the membrane material may be accessed and, for example, cut to a desired shape. Aspects also include methods and apparatus for advancing the membrane in the cartridge. Aspects of the present invention provide improved methods and devices that facilitate the handling and assembly of thin film membranes into membrane-containing devices, such as, fuel cells.
