NON-PUNCTURING FUEL CELL GAS DIFFUSION LAYER

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...

Zusammenfassung:	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.
