Abstract
The present invention relates to new compositions for bipolar plates and processes for manufacturing said compositions. More particularly, the invention relates to a process for manufacturing a composition, comprising the following steps:—mixing a thermoplastic polymer in the molten state with a first conductive filler in order to obtain a conductive thermoplastic polymer,—grinding said conductive thermoplastic polymer in order to reduce it to powder;—mixing the conductive thermoplastic polymer powder with a second conductive filler.”
Claims15
A process for manufacturing a composition, comprising the following steps:
- mixing a molten thermoplastic fluoropolymer with a first conductive filler so as to obtain a conductive fluoropolymer;
- milling said conductive fluoropolymer to reduce it to powder;
- mixing the conductive fluoropolymer powder with a second conductive filler.
A composition comprising a second conductive filler and particles of a conductive fluoropolymer, characterized in that the particles of the conductive fluoropolymer comprise a fluoropolymer matrix in which a first conductive filler is dispersed.
