Thermoplastic prepreg intermediate material for fuel cell separation plate and method for manufacturing thermoplastic prepreg for fuel cell separation plate by using same

A method for manufacturing a thermoplastic prepreg for a fuel cell separation plate, comprising:

• laminating a hydrophobic thermoplastic resin film, of which (i) a degree of crystallization is 1 to 20%, (ii) a thickness is 3 to 50 pm and (iii) a content of an electroconductive material is 1 to 20 wt. %, on at least one surface of a fiber base to prepare a thermoplastic prepreg intermediate material for a fuel cell separation plate;
• and
• pressurizing the prepared thermoplastic prepreg intermediate material for a fuel cell separation plate at a temperature higher than a melting point of the hydrophobic thermoplastic resin film,
• wherein the thermoplastic prepreg intermediate material consists of the hydrophobic thermoplastic resin film laminated on at least one surface of the fiber base, and wherein the laminated hydrophobic thermoplastic resin film is a single layer.
