| 摘要 |
The present invention provides a fuel cell separator containing an electroconductive resin composition, wherein the electroconductive resin composition is produced from a mixture containing: a thermosetting resin containing an epoxy resin; a curing agent; a curing accelerator; and a carbon material containing an expanded graphite, wherein the electroconductive resin composition has an elution characteristic so that a dipping water after dipping the electroconductive resin composition for 500 hours at 90° C., in which the volume of the dipping water is 1 cm<SUP>3 </SUP>with respect to the weight of the electroconductive resin composition of 5.1 g, has an electroconductivity of 50 muS/cm or less.
