Bac2 Conductive Composites

Schematic indication of bipolar plates in simplified PEM fuel cells. The bipolar plates and end plates (ElectroPhen ) were designed by Bac 2 Conductive Composites Inc. (http //www.bac2. co.nk/fuel-cell-appHcations/ (accessed Dec. 2008).)...

Furthermore, intrinsically conducting polymers (ICPs) such as polyanilines (PANI), polypyrroles, and polyphenylenes have been used as part of conductive composites on account of their much higher conductivity than other polymers. They are often mixed with other polymers as investigated by Taipalus (2001) and Totsra and Friedrich (2004). On the other hand Dweiri (2007) have found the addition of PANI to a composite of PP/carbon black/graphite for bipolar plates to be unsuitable for processing due to the poor thermal stability of PANI. The company Bac2 is currently the only manufacturer to use a patented electrically conductive polymer called ElectroPhen in their composite bipolar plates. 

Bac2 Ltd Formed in 2002 to develop commercial-scale electrically conductive polymer composites. Manufactures composite carbon bipolar plates using their patented Electrophen polymer.
