Abstract:
1. A method for manufacturing a composite separator for a polymer electrolyte membrane fuel cell, the method comprising: providing a carbon fiber reinforced composite material in the form of prepreg including a plurality of holes and graphite foils having the same size as the carbon fiber reinforced composite material; stacking the graphite foils on both sides of the carbon fiber reinforced composite material and forming air/hydrogen/coolant supply manifolds on both ends thereof; forming channels on an outer surface of each graphite foil by applying a high temperature and high pressure mold for channel formation; and allowing a connecting portion to be formed in each hole of the carbon fiber reinforced composite material as a portion of the graphite foils is filled into the holes by the high temperature and high pressure applied during the formation of the channels, wherein the graphite foils stacked on both sides of the carbon fiber reinforced composite material are conductively connected to each other.
