う問題がある。The thickness of the thermoplastic resin molding is 0.2 mm
It is desirable that the range is up to 2.0 mm. If the thickness of the thermoplastic resin molded product is less than 0.2 mm, it is brittle and easily cracked, which makes it difficult to handle. Further, particularly when used for a fuel cell separator, if the thickness exceeds 2 mm, the separator becomes thick and the fuel cell becomes large.

(Weight ratio) is good. If the proportion of the thermoplastic resin is less than 5, the proportion of the thermoplastic resin is small and molding becomes difficult. If the proportion of the thermoplastic resin exceeds 50, the proportion of the conductive agent is small, resulting in poor conductivity.
