Abstract

See full text

An apparatus and method provide for singulating thin and substantially porous material layers arranged in a stack. A pick head is positioned above the stack of material layers. An adhesive tape is stabilized against the pick head through use of a vacuum between the adhesive tape and the pick head. Contact is effected between the stabilized adhesive tape and the top material layer. The pick head is moved to move the top material layer from the stack to a predetermined location. While at the predetermined location, the adhesive tape is detached from the top material layer. The singulation apparatus and method are particularly well suited for destacking individual porous fluid transport layers (FTLs) from a magazine of FTLs during automated fuel cell assembly.
