PROBLEM TO BE SOLVED: To provide a method for producing a separator for a fuel cell, which is inexpensive, has good dimensional accuracy, and has no problem in separator characteristics such as electric characteristics, mechanical strength, gas impermeability, and liquid swellability. And a fuel cell using the fuel cell separator obtained by the method. SOLUTION: A fuel cell characterized in that components including expanded graphite powder and a molding resin are uniformly mixed, a tablet is molded, and then a main molding is performed at a temperature and pressure higher than the temperature at the time of tablet molding. Manufacturing method of separator for A fuel cell separator obtained by the above method and a fuel cell comprising the separator. |
