| 摘要 |
The present invention provides a method of producing a fuel cell separator in which at least a portion of a premolded article composed of a thermosetting resin and a carbon material, or a thermoplastic resin and a carbon material is provided with hydrophilicity, including the steps of: (1) treating the premolded article for enhancing affinity with a solution of a radically polymerizable monomer having a hydrophilic group and/or a functional group which can be converted into a hydrophilic group; (2) coating the solution of the radically polymerizable monomer having a hydrophilic group and/or a functional group which can be converted into a hydrophilic group, on the treated surface; (3) irradiating the treated surface with ionizing radiation; and (4) cleaning the fuel cell separator obtained through steps 1 to 3; wherein steps 1 to 4 are sequentially carried out, or step 1, step 3, step 2, and step 4 are sequentially carried out. |
