Polymer exchange membrane fuel cell (PEMFC) is an electrical energy-generating device that is renewable and environmentally friendly. However, the price of components in PEMFC is still relatively expensive and more studies are needed on making cheaper components in terms of methods and raw materials. In this research, the fabrication of gas diffusion layer (GDL) which is a component of PEMFC made from ramie fiber was investigated. The processes of preparing GDL in this research were divided into two parts: the process of making carbon from ramie fiber through pyrolysis process and fabrication of composite from carbon ramie fiber and urea formaldehyde resin (UFR) by hot press method. The carbon results from the process of pyrolysis of degummed ramie fiber with variations in pyrolysis temperature of 500 °C, 900 °C, 1100 °C and 1300 °C yield electrical conductivity values of 8.7 × 10−7 S/cm, 0.84 S/cm, 3.72 S/cm and 4.6 S/cm, respectively. The electrical conductivity of carbon ramie fiber was increased by degumming and increasing pyrolysis temperature. The 1300 °C carbon composite with a hydrophobic coating 10 wt.% FEP has an electrical conductivity of 0.25 S/cm and a water droplet angle of 133° (hydrophobic). Composites of carbon ramie fiber have potential as GDL in PEMFC.
