APPARATUS AND METHOD FOR AUTOMATICALLY STACKING FUEL CELL MATERIAL LAYERS

Stacking porous and non-porous material layers involves applying vacuum to a first porous layer to stabilize same relative to a support structure. The support structure and/or a non-porous layer are moved to establish contact between the non-porous layer and the first porous layer. The first porous...

Zusammenfassung:	Stacking porous and non-porous material layers involves applying vacuum to a first porous layer to stabilize same relative to a support structure. The support structure and/or a non-porous layer are moved to establish contact between the non-porous layer and the first porous layer. The first porous and non-porous layers define a sub-assembly. While applying vacuum to the sub-assembly, one or both of the support structure and a second layer are moved to establish contact between the second layer and the non-porous layer. Vacuum applied to the sub-assembly maintains positional stability of the sub-assembly layers relative to the support structure while the second layer is moved into contact with the non-porous layer. Vacuum is subsequently removed to facilitate transporting of the material layer stack. Material layers of a fuel cell, including first and second fluid transport layers and a membrane, are well suited for automated stacking.
