Considering diverse needed conditions, so far many materials have been studied as materials of bipolar plate for the fuel cell. At the first, plate which was made from graphite flat board having channel is that manufacturing cost of channel is high and due to the high brittleness, it is hard to reduce the thickness of plate. On the case of using a metal like stainless steel, there are some disadvantages such as high material density, high manufacturing cost and corrosion.
To make a completion of disadvantages, we are researching on a carbon conductive polymer composite material. A carbon conductive polymer composite material has advantages like taking low-cost manufacturing and making light weight and reducing the manufacturing time. And due to using polymer fiber, higher ductilities is possible. On account of the fact that PEMFC is working on low temperature (approximately 80℃) comparing with other fuel cell plate, carbon conductive polymer composite material can be used for the plate.
On this study, the goals are of establishing the manufacturing process of carbon conductive polymer composite material which is used for PEMFC and examining of mechanical characteristics of carbon conductive polymer composite material having superior electrical conductivity according to the change of fillers and forming conditions. And compression molding technique was used for processing, and graphite powder and carbon fiber was used as fillers.
As a result of the research, through the optimization of molding conditions using compression molding technique I made carbon conductive polymer composite material for fuel cell plate having superior electrical conductivity which is up to 180 S/㎝. on the case of powder/epoxy composite material, according to the increasing forming pressure, electrical conductivity and bending strength were increased and optimal forming pressure was 1000~1500psi that carbon powder's degree of fineness was fully made. Maximum impact load and absorbing energy of carbon fiber reinforced composite material were better than those of graphite powder/epoxy composite material. This shows that degree of fineness was fully made and strength was increased.
