发明名称 Composition and method for making fuel cell collector plates with improved properties
摘要 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 10 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.
