Graphite/phenolic resin (PF) composite bipolar plates used for polymer electrolyte membrane fuel cells (PEMFCs) were prepared by a compression molding process. The contact resistance between the composite plates and carbon paper were measured with a four-probe method. The influences of contacting pressure

PF content and compression molding parameters on the contact resistance were investigated.The results show that contacting pressure and PF content had a great influence on contact resistance. The contact resistance decreased with the increase of contacting pressure and increased with increasing PF content evidently. The compression pressure and temperature had a smaller influence on contact resistance compared with contacting pressure and PF content. The contact resistance increases slightly with increasing compression pressure. The compression time and temperature had no effect on contact resistance.
