In the last decade, numerous investigations have been devoted to the preparation of polypropylene–multiwalled carbon nanotubes (PP/MWCNT) nanocomposites having enhanced properties, and in particular, high electrical conductivities (> 1 S cm−1). The present work establishes that the highest electrical conductivity in PP/MWCNT nanocomposites is limited by the amount of nanofiller content which can...
Polymer electrolyte membrane fuel cells (PEMFCs) have the potential to play a major role as energy sources for transportation and portable applications because they feature high power density at relatively low operating temperatures. Bipolar plates are a key component of PEMFCs in terms of cost and weight. To date, many different materials for bipolar plates have been investigated and an alternative...
