NON-PUNCTURING FUEL CELL GAS DIFFUSION LAYER

According to the invention， the sheet 9 of carbon fiber paper is advanced from the first roll on the spindle 11 through the roller 14 around to the second roll around the spindle 15. Bending the sheet of carbon fiber paper around the roller 14 causes fibers vulnerable to entanglement to protrude outwardly from the surface， and these fibers are by razor-sharp blades 17 attached to the stop points 18. Shaved. In an alternative， a carbon fiber element 20， such as a fuel cell diffusion layer， can be secured within the bow jig 22， and a razor-sharp blade 31 rotates along the surface of the element to cut any protruding fibers Can be. A sheet of fiber carbon paper (9) is advanced from a first roll on a spindle (11) around a roller (14) to a second roll around a spindle (15). Bending of the sheet of fiber carbon paper around the roller (14) causes fibers that are prone to disentangle to protrude outwardly from the surface and are shaved off by a razor-sharp edge (17) affixed to a stationary point (18). Alternatively， carbon fiber elements， such as a fuel cell gas diffusion layer (20) may be fixed in an arcuate jig (22) and a razor-sharp edge (31) may revolve along the surface of the element to cut off any protruding fibers.

本发明中，编号为9的碳纤维纸（carbon fiber paper）片从主轴（spindle）11上的第一料卷送出，经辊轮（roller）14绕行后，收卷至主轴15上的第二料卷。将该碳纤维纸片在辊轮14处弯折，可使易缠结的纤维从表面向外突出，随后由安装在固定点18上的剃刀式锋利刀片（razor-sharp blade）17将这些纤维剃除。作为替代方案，可将碳纤维构件（如燃料电池气体扩散层（fuel cell gas diffusion layer）20）固定在弓形夹具（bow jig）22内，通过沿构件表面旋转的剃刀式锋利刀片31，切断所有突出的纤维。
