1. the manufacturing approach of separator for fuel battery, it is that the powder of carbon dust and thermosetting resin is made the method for separator for fuel battery with the mixture of given mixed as raw meal, the method is characterized in that,Said thermosetting resin is a phenol resin,Said method has compression forming operation and resin solidification operation;

  • In the said compression forming operation;

    Drop into said raw meal and cold moudling is the profiled sheeting of partition shape to mould;

    In the said resin solidification operation, be heated to the temperature more than the resin solidification temperature of said thermosetting resin at the said profiled sheeting that non-pressurised state will be compressed moulding through said compression forming operation after the said compression forming operation;

    And in said compression forming operation, apply the pressure more than or equal to 100MPa to said profiled sheeting, application time is 5~

    10 seconds.
