【 摘 要 】

The important part of fuel cell is the gas diffusion layer who made from carbon based material porous and conductive. The main goal of this research is to obtain carbon material from sugarcane bagasse with hydrothermal carbonization and chemical-physics activation. There were two step methods in this research. The first step was sample preparation which consisted of prepare the materials, hydrothermal carbonization and chemical-physics activation. The second one was analyze character of carbon using EDS, SEM, XRD, and LCR meter. The amount of carbon in sugarcane bagasse-carbon was about 85%-91.47% with pore morphology that already form. The degree of crystallinity of sugarcane bagasse carbon was about 13.06%-20.89%, leaving the remain as the amorphous phase. Electrical conductivity was about 5.36 x 10-2Sm-1- 1.11 Sm-1. Sugarcane bagasse-carbon has porous characteristic with electrical conductivity property as semiconductor. Sugarcane bagasse-carbon with hydrothermal carbonization potentially can be used as based material for fuel cell if only time of hydrothermal carbonization hold is increased.
