Abstract

The performance of polymer exchange membrane fuel cell (PEMFC) is depends to the bipolar plate. In this research, the alternatives material for bipolar plate that is graphite-epoxy composite has been study. Different ratio of graphite (G) and carbon black (CB) polymer exchange membrane fuel cell has been mixed with epoxy to fabricate the conductive composite bipolar plate. The composition of fillers: binder is fixed 80:20 and the percentage of CB has been varying from 5% up to 30% from total percentage of fillers. The material will be pre-mixing in the ball mill machine. The conductive composite will be fabricated by using hot compressing molding. Properties of the bipolar plate such as electrical conductivity, flexural strength, hardness and density will be measured. The result from the tests will be analyzed whether the properties of conductive composite were achieved and meted the DOE requirement. From the experiment that has been conducted, the critical loading of CB content in the composite is 20% and the present of carbon black in the composite improved the properties of graphite- epoxy composite such as electrical conductivity, flexural strength, density and hardness.
