2018 ABSTRACT Bipolar plates significantly
contribute to the development of the polymer electrolyte membrane
(PEM)
fuel cells technology due to their ability to produce high electrical
conductivity based on the type of materials used. Mismatching
of inappropriate materials and manufacture may lead to the inferior
performance of PEM
fuel cells. Hence, material development was determined
crucial to balance the overall performance of PEM fuels including the mechanical properties
and electrical conductivity of the materials. Studies on conductive
polymer composites (CPCs) offered filler with orientation
in terms of filler with aspect ratio and shape as an alternative
method to enhance the overall performance of the bipolar plate.
Filler orientations permit an excellent conductivity network formation
while controlling the filler alignment based on required applications.
This paper reviewed various studies of filler orientations including
materials used and methods of manufacture of CPC
materials for the effective development of bipolar
plate. The technique to orientate the filler was highlight in
terms of materials processing and its effects on the materials
performance. Keywords: Conductive polymer
