N2 - Electrical polymer composites for molding of bipolar plate are easily fabricated. In this study, PPS filled with 50wt% carbon fiber (CF) and PPS mixed with 50wt% CF + 20wt% Graphite (GP) were used for injection molding of a bipolar plate to study the associated fiber orientation and distribution and their effects on surface conductivity under various molding conditions. The flat plates were both convectional injection molded (CIM) and injection compression molded (ICM). In-plane conductivity (IPC) and through-plane resistance (TPR) of the bipolar plates was measured. Under proper molding conditions, TPR and IPC can be improved by 54% and 48%, respectively, in CIM, whereas TPR was improved by 70% and IPC improved by 184% in 1CM. IPC can reach 1 56S/cm when molded by ICM.
