of the biomass for solving the problem of biofuel production, and it can be used not only for biodiesel production but also for bioethanol production. Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources
extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder. Most commonly used solvent is Chloroform. After end of this extraction process, the solvent should be separated from water or other impurities and recycled to extraction system because most of solvent is expensive.

of fossil fuel. Fuel cell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development is still slight. To develop fuel cell technique as the core industry, we have to construct effective infrastructures from extraction to supply. So, in this project, our te
