INVESTIGATION OF MOLDING PARAMETERS ON GRAPHITE/EPOXY COMPOSITE-BASED BIPOLAR PLATES

In order to obtain a material suitable for manufacturing bipolar plates for PEM Fuel Cells the effect of molding parameters (pressure, temperature and time), relative to a graphite/epoxy composite of fixed composition, were studied and modeled by means of a two-level full factorial Design Of Experiment approach. In-plane conductivity and mechanical strength were the dependent variables.
