Abstract
A first fixture of a transportable fixture apparatus incorporates a substantially porous first region adapted to receive one or more porous and/or non-porous first material layers, such as fuel cell layers, and to facilitate formation of a vacuum between the first fixture and the first material layers. A second fixture incorporates a substantially porous second region adapted to receive one or more porous and/or non-porous second material layers and to facilitate formation of a vacuum between the second fixture and the second material layers. A stop arrangement protrudes from one or both of the first and second fixtures, and is situated peripheral to the first and second material layers when the first and second fixtures are brought into contact. The stop arrangement defines a cavity adapted to effect compression of the first and second material layers when the first and second fixtures are brought into contact.
