ELECTROCONDUCTIVE RESIN COMPOSITION, FUEL CELL SEPARATOR MADE OF SAID ELECTROCONDUCTIVE RESIN COMPOSITION, PROCESS FOR PRODUCTION OF SAID FUEL CELL SEPARATOR, AND SOLID POLYMER TYPE FUEL CELL USING SAID FUEL CELL SEPARATOR

摘要

The present invention provides: an electroconductive resin composition comprising:(A) a liquid crystal polyester resin capable of forming an anisotropic melt phase, in an amount of 100 parts by weight,(B) a carbodiimide compound in an amount of 0.01 to 30 parts by weight,(C) an electroconductive carbon powder in an amount of 50 to 3,000 parts by weight, and(D) a filler in an amount of 0 to 10,000 parts by weight; a fuel cell separator made of the above electroconductive resin composition; a process for producing the above fuel cell separator; and a solid polymer type fuel cell using the above fuel cell separator. The electroconductive resin composition alleviates the problems of the prior art, can be mass-produced, and is superior in high temperature resistance and hydrolysis resistance.
