GRAPHITE LAMINATE FUEL CELL PLATE

摘要

A laminated fuel cell plate (10) has a sheet metal layer (14) compression molded between two layers of expanded graphite (12, 16). The sheet metal lay er provides resilient support for making thinner plates. The sheet metal layer also functions as a permeability barrier, which allows the conductivity of t he expanded graphite layers to be enhanced. Features are molded into the graphi te layers for such purposes as alignment, sealing, and flow control.
