Expanded and nano-structured carbonaceous graphite for high performance anisotropic fuel cell polymer composites

We disclose a novel high pressure design, non-destructive structural analysis and fabrication of bipolar plate composites (BPC) that are highly conductive yet mechanically flexible. Here we report the highest electrical conductivity of 221 S cm−1 of a BPC by tailoring graphitic structure of carbon nanomaterials and their functional attributes through enhancement of in-plane conductivity as well as mechanical strength; another advanced BPC also …
