Patent number: 10693151Abstract: This invention relates to a bipolar plate for a fuel cell having a controlled structure of carbon materials and a method of manufacturing the same, the method including obtaining a masterbatch by mixing a first carbon material powder having a size ranging from 0.1 to 200 ?m with a polymer resin, forming a masterbatch powder by crushing the masterbatch, preparing a conductive composition by mixing the masterbatch powder with a second carbon material powder having a size ranging from 300 ?m to 1 mm, and manufacturing a bipolar plate by subjecting the conductive composition to compression molding. Thereby, carbon materials in a powder phase having different sizes can be uniformly dispersed via a masterbatch to thus shorten a conductive path, thereby decreasing electrical resistivity, and furthermore, dispersion in the polymer resin can be improved, thereby increasing flexural strength.Type: GrantFiled: April 2, 2018Date of Patent: June 23, 2020Assignee: Morgan Co., Ltd.Inventors: Jong Seok Woo, Mun Hee Lee, Hong Beom Ju, Kwang Sang Park, Sung Hoon Park

Publication number: 20200196435Abstract: The present invention relates to a method of manufacturing a multi-structural high-heat-dissipation part having the controlled packing density of a carbon material and to a multi-structural high-heat-dissipation part manufactured thereby, the method including preparing a mixture by mixing a binder pitch with a carbon material including a first carbon material powder and a second carbon material powder having a smaller diameter than the diameter of the first carbon material powder, forming a compact from the mixture using a hot-forming process, and producing a graphitized pitch/carbon material compact by subjecting the compact to graphitization through heat treatment and cooling. Thereby, the packing density of the carbon material can be improved through bimodal distribution using pieces of carbon material having different diameters, thus increasing thermal conductivity in in-plane and through-plane directions and strength.Type: ApplicationFiled: September 25, 2019Publication date: June 18, 2020Inventors: Jong Seok Woo, Mun Hee Lee, Byung Choon Kim, Kwang Sang Park, Sung Hoon Park
