Abstract
A fuel cell separator containing conductive material and epoxy resin is provided. In the fuel cell, the epoxy resin is made of solid epoxy resin whose epoxy equivalent weight is 300-500. Further, according to another fuel cell separator, raw materials containing not lower than 60 weight % of conductive material and 34-40 weight % of resin material are kneaded, and adjusted to have a flow index of 5-20%. A kneaded compound is compression-molded so that a fuel cell separator is obtained.
