Abstract

See full text

This precursor sheet for a fuel cell separator comprises a conductive substrate sheet, a dense layer including first graphite particles, and a conduction layer including second graphite particles, wherein the dense layer and the conduction layer include a resin, the first graphite particles have a volume resistivity of 20 mΩ·cm or greater and a bulk density of 1.7 g/cm3 or greater when compressed at 30 MPa, and the second graphite particles have a volume resistivity of less than 20 mΩ·cm and a bulk density of 1.5 g/cm3 or greater when compressed at 30 MPa. This precursor sheet for a fuel cell separator provides a fuel cell separator that has excellent shapability and good mechanical strength, conductivity, and gas impermeability.
