Latest Patents

Jee Sung Yi's latest patents include a thermoplastic prepreg intermediate material for fuel cell separation plates and a method for manufacturing this thermoplastic prepreg. The intermediate material comprises a hydrophobic thermoplastic resin film and a fiber base. The film has a degree of crystallization ranging from 1 to 20%, a thickness between 3 to 50 µm, and contains an electroconductive material of 1 to 20 wt. %. This innovative design allows for the production of a thin and lightweight fuel cell separation membrane that exhibits excellent durability. The method for preparing the thermoplastic prepreg involves laminating a thermoplastic resin film on a matrix fiber and heating it to a temperature above the melting point of the film. This process ensures uniform impregnation of the matrix fiber, resulting in a product with increased rigidity and reduced thickness.
