Abstract:
Among many fuel cells, low-temperature fuel cells (PEMFC, DMFC) are attracting much attention for home and mobile power sources due to their attractive advantages such as high power density, low operating temperature, convenient fuel supply, and long life. A bipolar plate, one of the core materials that are composed of stacks by connecting multiple unit cells, provides electrical connection between cells as a support for a fuel cell structure. Due to the characteristic structure, the Department of Energy (DOE) has special requirements for bipolar plates, the most important of which are excellent electrical conductivity and high mechanical strength. Among various carbon materials, CNT refers to a fibrous nano-carbon material with a rolled graphene sheet. It has excellent dimensional stability, mechanical strength, electrical properties, etc. Its importance is emerging as a high-tech material. Therefore, in this study, to improve the properties of the graphite bipolar plate for fuel cells, optimum process conditions were selected using graphite of various particle sizes. Mechanical and electrical and chemical properties were evaluated. when the content of CNT increased, the mechanical properties of CNT and nm-sized CNTs increased by matrix function between μm-sized graphite particles. This study also shows that when the CNT content exceeds 7wt%, overall mechanical properties such as density, hardness, and flexural strength decrease. In addition, as a result of the analysis of the overall mechanical properties, the wet manufacturing process has excellent properties in common compared to the dry manufacturing process.
