PURPOSE:To improve the gas impermeability, electric conductivity, and mechanical strength of a carbon plate such as a carbon thin plate for a fuel cell separator. CONSTITUTION:A binder carbonizable or able to be graphitized such as phenol resin is impregnated into a fiber able to be made a carbon fiber such as a novolak type phenol resin fiber, and is dried and ground to prepare a milled fiber prepreg. The milled fiber prepreg is pressurized and heated to be formed in a plate state, and is carbonization-or graphitization-treated to obtain a carbon plate. |
