The most important component in a fuel cell is a bipolar plate,
Due to different plate materials, bipolar plate can be divided into graphite bipolar plate, metal bipolar plate, and composite bipolar plate, wherein graphite bipolar plate is currently a major research direction.
bipolar graphite plate
A kind of the materials for the bipolar plate of proton-exchange membrane fuel cells (PEMFC) were fabricated
by the hot-pressure molding with graphite powders and phenol-formaldehyde (PF) resin powders. The factors including the PF resin content , the graphite particle size and curing temperature which affected the conductivity and bending strength of the composite were investigated. The results showed that the conductivity decreased and bending strength increased with the increasing of PF resin content ,that the conductivity and bending strength would increase firstly and then decreased with the increasing of graphite particle size ,and that the conductivity surged greatly and bending strength would increase firstly and then decrease with the increasing of curing temperature ,that the electrical conductivity and bending strength of the composite were 142S/ cm,61.6 MPa ,when the PF resin mass content ,graphite particle size and curving temperature were 15%,105μm and 240 ℃.
CFCCARBON has developed ultra-thin graphite bipolar plates, which greatly reduce the size and weight of the fuel cell stack.
Our materials are specially selected and qualified for fuel cell , which allows very high fuel cell performance with very competitive cost.
