Abstract

The invention relates to a method for producing a composition comprising the steps of: melt-blending a fluorinated polymer, preferably a polyvinylidene fluoride polymer, with a first conductive filler so as to obtain a conductive fluorinated polymer; grinding to powder said conductive fluorinated polymer; mixing the powder of conductive fluorinated polymer with a second conductive filler. The invention also relates to a composition comprising a second conductive filler and particles of conductive fluorinated polymer, wherein the particles of conductive fluorinated polymer comprise a fluorinated polymer matrix in which a first conductive filler is dispersed The invention also relates to a method for producing a bipolar plate and to a bipolar plate.
