PROBLEM TO BE SOLVED: To obtain a highly efficient solid high polymer molecule fuel cell having a high gas sealing nature and an outstanding anti-impact nature, in which neither a cracking nor a fracture is generated in assembly, by using one part or all of a fuel cell separator, while enabling to mass-produce efficient ly the quality fuel cell separator which has high elasticity, high conductivity, and outstanding gas impermeability. SOLUTION: In the fuel cell separator which has a gas supply slot at one side or both sides formed with a composite for fuel cell separator composed of a conductive carbon powder and a binding material as principal components, the characteristics of the fuel cell separator and its manufacturing method, and the solid high polymer molecule fuel cell are that a total occupied area of the conductive carbon powder which has the maximum length of the long axis direction in the perpendicular section of the above fuel cell separator of 70 μm or more, and the maximum length of the short axis direction of 30 μm or more, is 50% or more of the area of the perpendicular section. |
