A method and composition is disclosed for making conductive flow field separator plates having reduced resistivity, lower weight and lower cost. The plates are made by blending from about 0.5 wt% to about 40 wt%, preferably from about 1 wt% to about 30 wt%, most preferably from about 5 wt% to about 20 wt%, of the liquid crystal polymer; from about 0.5 wt% to about 40 wt%, preferably from about 1 wt% to about 30 wt%, most preferably from about 5 wt% to about 20 wt% of the poly(styrene-co-maleic anhydride); and from about 20 wt% to about 99 wt%, preferably from about 60 wt% to about 98 wt%, most preferably from about 70 wt% to about 90 wt% of the conductive filler. The blend is then moulded to form the conductive flow field separator plates. |
