A fuel cell separator is produced by forming a fuel cell separator resin composition including, as essential components, (A) an epoxy resin; (B) a curing agent; (C) a curing accelerator; and (D) a carbon material, in which the content of the (D) is 50 to 85% by mass based on the total amount of the composition, in which the (D) includes high crystalline artificial graphite having an average particle size of 100 µm or more and less than 150 µm in an amount of 5 to 100% by mass based on the total amount of the (D), and in which the content of the (C) is 0.1 to 20 parts by weight per 100 parts by weight of the (B). The resin composition is excellent in electric conductivity and fluidity and contains little impurities, and can provide a fuel cell separator which is excellent in electric conductivity and dimensional accuracy, and has no fear of causing deterioration in performance of a solid electrolyte.
一种燃料电池隔膜是通过形成一种燃料电池隔膜树脂组合物而制成的,该组合物的主要成分包括:(A) 环氧树脂;(B) 固化剂;(C) 固化促进剂;和 (D) 碳材料,其中 (D) 的含量为组合物总量的 50% 至 85%(按重量计),其中 (D) 包括平均粒径大于等于 100 微米且小于 150 微米的高结晶人造石墨,其含量为 (D) 总量的 5% 至 100%(按重量计),其中 (C) 的含量为 0.1 至 20 份(按重量计),每 100 份(按重量计)(B)。该树脂组合物具有优异的导电性和流动性,且杂质含量极少,可提供导电性和尺寸精度优异的燃料电池隔膜,且不会导致固体电解质性能下降。
