Abstract: Expanded graphite–polyimide composites for fuel cells containing from 0 to 23 wt% expanded graphite were produced by direct compression molding after pre-mixing the binder and filler. The percolation threshold in this system was determined to be 2.5%, while the corrosion current was 3 × 10⁻² μA cm⁻², and the composites were thermally stable up to 400 °C.

Keywords: bipolar plates, conductive polymer composites, expanded graphite, polyimide, fuel cell, percolation threshold.
