SEPARATOR FOR FUEL CELL AND MANUFACTURE METHOD FOR THE SAME |
摘要 |
To provide a separator for a fuel cell made of graphite excellent in mechanical strength and gas impermeability as well as electric characteristic properties, a separator for a fuel cell is produced from a molded body produced by filling a graphite powder 21 whose surface is coated with resin 20 in a molding die and by pressure-molding the powder. Such a molded body is provided with excellent mechanical strength of 40 MPa of bending strength or higher, 10 x 10-8 cc .cndot. cm/cm2 .cndot. sec .cndot. atm of gas permeability or lower, and electric property of 10 x 10-3 .OMEGA. .cndot. cm of the volume resistance or lower even if the content of resin is decreased to as low as 1 0 to 24 wt.%. |
