Beschreibung
Zusammenfassung:	A cutting apparatus for use with a platen die station is employed for cutting relatively thin planar material layers, such as thin material layers used in the construction of fuel cells. The cutting apparatus includes a die having a substantially planar first surface and a substantially planar second surface. A cutting surface and at least one bearer surface respectively protrude from the first surface of the die. A height of the bearer surface is substantially equal to a height of the cutting surface, such that the bearer surface prevents damage to the cutting surface when the cutting surface and bearer surface are moved to contact an anvil surface of the platen die station. One or more layers of a compliant material, such as polyethylene or polypropylene, may be situated in contact with the second surface of the die to add compliance to the cutting apparatus.
