Phenol Formaldehyde Resin /Graphite Composite Bipolar Plate Prepared by Pressure Molding

A kind of low-cost PF resin/graphite composite was obtained by hot pressure molding.Mechanical properties and conducting properties of the composite were tested and analyzed.The results show that PF resin content mainly influence composite properties.With PF resin content less than 20%,the composite had fairly good conducting property.As curing pressure and curing temperature increased,the bending strength could be improved,but the conducting property would be reduced apparently.Moderate curing pressure and curing temperature were beneficial to composite properties.
