Abstract

PURPOSE:To manufacture a separator for fuel cells with long life and relatively higher electric conductivity by heating and press-molding a paste mixture of fluororesin powder and graphite fine powder. CONSTITUTION:Fluororesin and graphite fine powder are mixed in an adequate proportion, and the mixture is dispersed in water to prepare a paste. The paste is heated at 280-380 deg.C, and press-molded to form a sheet separator. Ribbed substrates 19 are constitured by combining an electrode 2 and a rib 4, and an electrode 3 and rib 5 separately, and unit cell is constituted by pairing the ribbed substrates 19 through an above mentioned separator 18 in which grooves 7 of each substrate is opposed each other, and a fuel cell is constituted by laminating the unit cells. The separator 18 is manufactured easily at low cost, the thin thickness of the separator reduces the heat loss due to ohmic drop, and the thermal efficiency of a cell can be improved.
