Graphite laminate fuel cell plate

摘要

A laminated fuel cell plate has a sheet metal layer compression molded between two layers of expanded graphite. The sheet metal layer provides resilient support for making thinner plates. The sheet metal layer also functions as a permeability barrier, which allows the conductivity of the expanded graphite layers to be enhanced. Features are molded into the graphite layers for such purposes as alignment, sealing, and flow control.
