Abstract:
1. A method for producing a sheet molding compound composition for use as a fuel cell flow field plate or bipolar plate material, said method comprising: (a) providing a continuous sheet of a substrate material; (b) feeding a resin mixture to a surface of said substrate material sheet, said resin mixture comprising a thermoset resin and a conductive filler; (c) providing a continuous sheet of flexible graphite onto said resin mixture in such way that said resin mixture forms a core layer sandwiched between said substrate material sheet and said flexible graphite sheet to obtain a laminated structure; and (d) compressing said laminated structure to obtain said sheet molding compound composition which is collected on a winding device, the sheet molding compound having a conductivity greater than 100 S/cm.
